Opis:

Miocene alluvial/fluvial-lacustrine deposits composed of three lignite successions (Lower, Middle, and Upper) are exposed in Soma coalfield located near the northern Aegean Sea coastline of the Western Anatolia. The total thickness of the coal successions is about 900 m, and they rest unconformably on the Mesozoic carbonate/siliciclastic basement rocks. Recognised lithofacies of coal successions have been arranged to fourteen facies assemblages and interpreted as environments.Lower Coal succession was deposited in an alluvial fan to plain and perennial forest mire system resulting in a subbituminous lignitic coal, in average 20 m thick. Freshwater carbonate-dominated Middle Coal succession, having lignite beds ranging from 0.5 to 2.5 m, was formed in floodplain environment, including shallow freshwater carbonate lakes and/or ponds, and frequently drying poor forest mires of an anastomosed river system. Volcanism-induced Upper Coal succession was deposited in fluvial channel, floodplain, and probably in allochthonous peat mires of a braided river system that rapidly got buried and/or eroded by volcaniclastic apron deposits, and culminated by large carbonate-dominated perennial shallow lakes.The Miocene coal successions were probably deposited in the fault-controlled karst-based palaeovalleys and lowlands of the intramountain palaeomorphology that were patterned by the Early Tertiary collision of the Eurasia and Anatolian plates. The coal successions was faulted by the extensionally tectonic regime and covered with Plio-Quaternary deposits.

Integrated sedimentological and palaeontological study of borehole cores through plat orm siliciclastic deposits of the southernmost part of Brunovistulicum (S Moravia) shows convincing evidence for the Cambrian age of a considerable portion organic-walled microfossils of Late Proterozoic (Ediacaran) age have been found in a sample from the Menín-1 borehole. Thirty genera characteristic of the Ediacaran have been recognized. Part, though, of the siliciclastic succession of S Brunovistulicum is Devonian in age. The platform deposits studied are consid red to have the same source area but the degree of maturity of the Devonian clastics rocks is generally higher than that of the older strata. Facies analysis indicates a predominance of deltaic settings (braided and fan del tas); similar sedimentary environments are suggested for both the Ediacaran/Cambrian and Devonian successions.

Opis:

The Middle Miocene (Badenian) gypsum sequence was investigated by means of facies analysis on the Miechów Upland in the environs of Racławice, about 40 km northeast of Cracow. The region lies at the northwestern margin of the Carpathian Foredeep and has been omitted in detailed investigations until now. Five gypsum facies were distinguished: giant gypsum intergrowths, grass-like gypsum, palisade gypsum, sabre gypsum and microcrystalline gypsum. Except for the palisade gypsum, the other facies were described from the adjacent Nida area. The vertical arrangement of the facies is generally the same along entire northern margin of the Carpathian Foredeep. The studied sequence is reduced in thickness (up to 30 m) in comparison to the Nida area (up to 50 m). The lower part of the section, composed of the giant gypsum intergrowths and grass-like gypsum, is distinctively reduced. It is often replaced by a thin layer of palisade gypsum. The microcrystalline gypsum and the sabre gypsum are the most common facies. The giant gypsum intergrowths and the grass-like gypsum occur in the northern part of the Racławice area, while the palisade gypsum dominates in the southern part. The gypsum basin of the Miechów Upland developed in a similar way as the basin of the Nida area, but was shallower and its brines underwent more often dilution. The basin-floor morphology probably showed a variety of features.read in the deeper waters of the northwestern Proto-Caribbean basin.
Badeńskie osady ewaporatowe zapadliska przedkarpackiego wzbudzają coraz większe zainteresowanie dzięki rozwojowi analizy facjalnej. Utwory gipsowe Wyżyny Miechowskiej w południowej Polsce były omijane w dotychczasowych szczegółowych analizach ze względu na brak dużych odsłonięć w tym rejonie. W niniejszej pracy przedstawione są pierwsze wyniki analizy facjalnej gipsów okolic Racławic w południowej częoeci Wyżyny Miechowskiej, 40 km na północny-wschód od Krakowa (Fig. 1). W pracy porównano profil gipsowy badanego obszaru z dobrze rozpoznanym profilem gipsów nadnidziańskich. Osady ewaporatowe Wyżyny Miechowskiej są podoecielone przez utwory dolnego lub środkowego badenu, do których należą piaski heterosteginowe oraz warstwy baranowskie (Fig. 2; Krach, 1947; Radwański, 1968). Gipsy mogą również leżeć bezpośrednio na górnokredowym podłożu (Radwański, 1968). Osady ewaporatowe są przykryte przez utwory górnego badenu lub sarmatu lub przez utwory czwartorzędowe (Osmólski, 1972; Woiński, 1991). Badaniami objęto 10 następujących odsłonięć: Kowary, Małoszów, Pałecznica, Podgaje, Głupczów, Racławice-źródło, Racławice-góra Widnica, Kooeciejów, Kowalówka i Działoszyce (Fig. 3). Wyróżnionych zostało pięć facji gipsowych: gipsy szklicowe, gipsy trawiaste, gipsy palisadowe, gipsy szablaste i gipsy mikrokrystaliczne (sensu Bąbel, 1999a, oprócz gipsów palisadowych). Gipsy szklicowe i trawiaste występują na badanym obszarze jedynie w postaci niewielkich bloków i rumoszy (Głupczów, Kooeciejów, Kowalówka, Działoszyce) dlatego nie zostały one dokładnie scharakteryzowane. Gipsy palisadowe, gipsy szablaste i gipsy mikrokrystaliczne są odsłonięte stosunkowo dobrze (Fig. 4). Gipsy palisadowe, po raz pierwszy opisane szczegółowo w niniejszej pracy, a stwierdzone już przez Bąbla (1987, Pl. 7, Fig. 2; 1990, Phot. 3-5, 16) są zbudowane z kryształów gipsu osiągających do 0.7 m długości, podobnych do kryształów szklicowych (Fig. 5). Kryształy palisadowe mają kształt zbliżony do prostopadłościanów i nie tworzą zrostów. Częste są ślady rozpuszczania. Gipsy palisadowe tworzyły się w podobnych warunkach jak gipsy szklicowe (Bąbel, 1999a; Kasprzyk, 1999; Peryt, 1996). Narastały one na dnie płytkiego basenu ewaporatowego w postaci zwartych pokryw. Krystalizacja gipsu była często przerywana epizodami dopływu wysłodzonych wód, które częściowo rozpuszczały powsta ły gips. Gipsy szablaste zbudowane są z długich, zakrzywionych kryształów gipsu, przypominających szable (Fig. 6; Bąbel, 1999a; Kasprzyk, 1999; Peryt, 1996 etc.). Warstwa gipsów szablastych dzieli się na dwie części, dolną i górną, o różnym wykształceniu. W dolnej części przestrzenie pomiędzy kryształami szablastymi (do 0,5 m długości) wypełnione są przez chaotycznie ułożone, drobne kryształy o pałeczkowatym pokroju. Struktura ta przypomina gipsy szkieletowe sensu Kasprzyk (1993). W górnej części przestrzenie pomiędzy kryształami szablastymi (do 1,18 m długooeci) wypełnia gips mikrokrystaliczny. Sedymentacja gipsów szablastych przebiegała identycznie jak na Ponidziu (Bąbel, 1999a; Kasprzyk 1993, 1999). Kryształy narastały na dnie basenu w solance o rozwarstwieniu gęstościowym. Pod koniec sedymentacji zasolenie wzrosło na tyle, iż doszło do krystalizacji gipsu w toni wodnej. Gipsy mikrokrystaliczne są zbudowane z bardzo drobnych kryształów gipsu (do 0,05 mm, Kwiatkowski, 1972; Niemczyk, 1988; Kubica, 1992; Bąbel, 1999a). Najczęstszymi strukturami sedymentacyjnymi są: płaska laminacja, laminacja falista, powierzchnie rozmycia, brekcje, mikrouskoki i mikrofałdy (Fig. 7). Ślady po kryształach halitu występują rzadko. Gipsy mikrokrystaliczne powstały z osadzenia na dnie basenu kryształów wytrąconych w toni wodnej lub redeponowanych (Pawlikowski, 1982; Bąbel, 1999a; Kasprzyk, 1999). Do nasycenia solanki względem halitu dochodziło epizodycznie. Gipsy mikrokrystaliczne zostały częściowo diagenetycznie przekształcone w gipsy porfiroblastyczne (Bąbel, 1992). Gipsy szablaste i mikrokrystaliczne są najbardziej rozprzestrzenione i występują na całym badanym obszarze (Fig. 8). Gipsy palisadowe dominują na południu badanego terenu, pomiędzy Kowarami i Głupczowem, podczas gdy gipsy szklicowe i trawiaste występują głównie na północ od Głupczowa (Fig. 8). Pionowa sukcesja gipsów Wyżyny Miechowskiej jest stała, identyczna jak w całym północnym obrzeżeniu zapadliska przedkarpackiego (Fig. 9). Całkowita miąższooeć sekwencji gipsów rzadko osiąga 30 m, czyli jest o ok. 20 m mniejsza niż na Ponidziu (Fig. 10). Szczególnie zredukowana jest dolna część profilu obejmująca gipsy szklicowe i trawiaste, które często zastąpione są jedną cienką warstwą gipsów palisadowych (Fig. 10). Przebieg sedymentacji gipsów nie odbiegał znacząco od sedymentacji gipsów Ponidzia. Basen Wyżyny Miechowskiej był prawdopodobnie płytszy i miał bardzo urozmaiconą morfologię dna. Często dochodziło również do rozcieńczania wód basenu przez wody z lądu.

Opis:

Sedimentary features of the Cambrian-age succession transected in seven borehole cores sited in the Podlasie region document vertical and lateral variations of shallow-marine sedimentary facies, deposited at the rifted western margin of the Baltica Palaeocontinent. The boreholes are distributed along two lines of cross-section (E–W and NE–SW) running roughly perpendicular to the margin of the palaeocontinent. The easternmost borehole represents a proximal setting located on a relatively stable, shallow basement in the east; the remaining boreholes document conditions of deposition in the subsiding shallow-marine basin, extending towards the SW. Fourteen sedimentary facies defined on the basis of their lithological and sedimentary features are interpreted in terms of the sedimentary environments they represent. Strata deposited upon the stable craton in the east document a stratigraphically condensed succession of proximal facies, 240 m thick, whereas a sequence three times thicker is positioned distally, 170 km to the west. Facies associations in the proximal section represent the lower to upper shoreface in the lower part of the section and evolve upwards to the intermediate shoreface. Facies complexes in the remaining, intermediate and distal areas form a symmetrical megasequence, composed of a positive (i.e., fining-upwards – FU) transgressive sequence, overlain by a negative (coarsening-upwards – CU) regressive sequence. The vertical arrangement of the sedimentary subenvironments during the transgression indicates a tidally influenced shoreline followed by oscillations between the swash zone, the upper, intermediate and lower shoreface, and the offshore. The symmetry of the megasequences and the rhythmic pattern of the component facies complexes indicate that the intensity of supply in the terrigenous material and the efficiency of its reworking and redistribution within the basin were similar during the transgression and the regression. The facies types and variations within the basal part of the succession reflect syndepositional movements of tectonic blocks parallel to the rifted basin margin. Differences in total thickness and facies associations between the two lines of cross-section approximately perpendicular to the basin margin indicate that sedimentation was also influenced by a synsedimentary hinge fault, extending in a WSW–ENE direction.

Opis:

An apparent contradiction between structural and sedimentological indications commonly used for discrimination of the overturned and non-overturned beds during geological mapping was found at Parsovice, a site situated in the easternmost part of the European Variscides. An outcrop of folded Lower Carboniferous siliciclastic rocks of the "Culm fades" lies on the NE margin of the Bohemian Massif, in the SE part of the Malenik Block (Moravia, Czech Republic). Flute casts in the steep overturned limb of a tectonic fold demonstrate the normal stratigraphic polarity of the bed. At the same site, a slump-related isoclinal fold was found. The apparent contradiction between structural (relation of cleavage and bedding) and sedimentological (flute casts on bed soles) indications is explained by a combination of successive phases of slump- and tectonically-related folding.

The deposits of the Niżniów Formation, exposed around Niżniów, mainly on the banks of Dnister River, accumulated in the most proximal, marginal position of the latest Jurassic-earliest Cretaceous epicontinental basin on the SW margin of the East European Platform. The Niżniów Formation directly onlaps a Palaeozoic substrate and consists of transgressive cliff-derived conglomerates, and sandstones and marls which pass laterally into shallow marine carbonates: mainly biomicrites, oncomicrites, and pelmicrites with an abundant benthic fauna dominated by nerineid gastropods. The thickness of the formation in the area studied ranges from 0 to more than 20 metres and was controlled bymorphology of the pre-transgression substrate (mainly built of Devonian clastic rocks), synsedimentary fault tectonics and pre-mid-Albian erosion. The age of the Niżniów Formation can be determined, on the evidence of benthic foraminifers encountered in thin sections, as most probably late Tithonian-early Berriasian.

Phymatellid demosponges are common fossils in the Campanian deposits of central Europe. In Poland, the Campanian phymatellids were known mostly from the opoka facies of the Miechów Synclinorium (southern Poland), where they occur mainly in the characteristic horizons of siliceous nodules in the lower Campanian opoka succession. Similarly preserved early Campanian phymatellids were identified in a redeposited lithistid assemblage in the Neogene gravels, exposed in the Bełchatów Lignite Mine (Mogilno-Łódź Synclinorium, central Poland). Rare phymatellids were noted for the first time in the upper Campanian gaize of the Miechów Synclinorium. The taxonomic descriptions of 16 phymatellid species presented here, including one new species, Kalpinella fragilis, completes existing knowledge of the taxonomic diversity of these sponges in the Late Cretaceous basins of central Europe. The present study also supplements the data on the stratigraphic ranges and spatial distribution of these species. The palaeoecology of Cretaceous phymatellids is discussed on the basis of their occurrence in the various facies.

Opis:

A Wenlock to Ludlow terrigenous-carbonate succession in the Vidukle core in Central Lithuania represents a deep shelf environment with a general upwards-shallowing trend, interrupted by brief deepening episodes. The carbon isotope trend, based on 115 whole-rock analyses, shows three main excursions: (1) a major excursion (δ13 C values reach 3.2‰) in the lower Wenlock, (2) low shifts (1.3‰ and 1.6‰) at two levels in the upper most Wenlock Siesartis Formation corresponding to the Monograptus ludensis Biozone, (3) the most prominent excursion (δ13 C values reach 8.2‰) occurs in the upper Ludlow Mituva Fm. The upper Ludlow excursion is dated by the last occurrences of Polygnathoides siluricus below the main shift and the appearance of Ozarkodina wimani and O. crispa above the excursion. The excursion stratigraphically coincides with the Lau oceanic Event and is correlated with the mid-Ludfordian Neocucullograptus kozlowskii-Bohemograptus bohemicus tenuis Biozone. Changes in the carbon isotope trend are in general harmony with some aspects of the rock (CaO, terrigenous component) and fossil content of the section. The data presented are consistent with an arid climate model for the Ludfordian isotope event.

Opis:

The depositional history and facies heterogeneity of the epigenetically dolomitized Middle Triassic carbonates of southern Poland are poorly recognized, and existing concepts of fluid circulation entirely overlook the primary lithology as a factor controlling fluid flow. This study reconstructs the consecutive phases of Kraków-Silesia Sub-basin history in the Anisian and highlights their influence on the development of the so-called “ore-bearing dolomite”. Extensive fieldwork and microfacies analyses were carried out in order to decipher the original depositional fabric of the ore-bearing dolomites. As a rule, epigenetic dolomitization affected a horizon of porous strata, 35 m thick and resting directly on impermeable, wavy-nodular clay-rich calcilutites of the Gogolin Formation, which represent the interval of deepest and fully marine (offshore) sedimentation. The sedimentary succession of the porous strata is bipartite. The lower part (Olkusz Beds) is composed of Balanoglossites and Thalassinoides micritic firmgrounds and peloidal packstones-grainstones, representing shoreface-foreshore facies assemblages, whereas the upper part (Diplopora Beds) consists of dolocretes, rhizolites, cryptalgal laminites, peloidal packstones-grainstones and bioturbated fine-grained dolostones, formed in a system of tidal flats and lagoons. These two parts are separated by a subaerial disconformity, which marks a sequence boundary. During emersion, the underlying deposits were subjected to meteoric diagenesis, which led to the development of moldic porosity. This combination of depositional history and diagenetic alteration determined the routes of initial migration of dolomitizing solutions on the one hand, and the location of cavern formation on the other. Owing to progressive dissolution, small caverns were changed into large karstic forms, in which the ore minerals precipitated ultimately. These findings emphasize the importance of sedimentological analysis to the understanding of the evolution of the Kraków-Silesia ore province.

Opis:

The study area is located in Aydýncýk (ÝÇEL) area where Early Cambrian rocks are represented by the Hüdai Formation. The formation represents three different parts in the vertical sequence which has a thickness of approximately 830 metres. The basal part of the formation consists of a rhytmic alternation of horizontal laminated sandstone, ripple trough cross-laminated sandstone, mixed sandstone-shale, and rarely metashales. The middle part comprises dominantly metashales. The upper part is made up by an alternation of horizontal laminated sandstone, mixed sandstone-shale and rarely metashales. Vertical variations in the formation is caused by marine transgressious and regressious, and by fluctuations in sediment supply. Lower to middle parts of the formation characterize a fining-upward sequence, and middle to upper parts display a coarsening-upward sequence. In the Hüdai Formation, four lithofacies are recognized based on lithology and sedimentary structures. These are (1) horizontal laminated sandstone (predominantly quartzarenite) indicating deposition from tidal currents during the high velocity phases of tidal cycles; (2) ripple cross-laminated sandstone (predominantly quartzwacke) deposited in lower part of intertidal (sand-flat) environment; (3) mixed sandstone-shale revealing deposition in mid-intertidal flat environment; and (4) shale (or metashale) deposited mainly in upper intertidal (mudflat) environment.

Opis:

The Triassic Fatricum basin studied in the Belanské Tatry Mts. (Slovakia) was a relatively stable and restricted platform area influenced by eustatic and climatic fluctuations. During the early Triassic the platform was influenced by continental clastic sedimentation intermittent with shallow marine transgressions when carbonate sediments formed. Common occurrence of carbonized plat debris suggests relatively humid climatic conditions dominating during this interval (Werfenian facies). Significant climate aridisation was concurrent with the beginning of the Middle Triassic transgression as indicated by evaporitic fabrics common within the entire Middle Triassic carbonate succession. The Middle Triassic has been divided into several lithofacies complexes reflecting the interplays between the eustatic and climatic fluctuations. The lower Middle Triassic complex (lower-middle Anisian?) displays dominance of calcareous sediments indicating free communication with the open ocean. The subsequent intervals are rather uniform facies assemblage composed by dolomites and evaporites formed in a restricted and stagnant basin. The basin has been strongly influenced by subtropical storms, particularly common in the late Anisian. Transgression pulse in the early Ladinian involved growth of microbial colonies building thrombolitic biostromes. Final shallowing by the end of Ladinian led to replacement of carbonate sediments by continental clastics of the Carpathian Keuper. These sediments, mostly of alluvial nature, comprise plant debris what suggests climate pluvialisation in Carnian times.

Opis:

A generalized workflow of scientific process requires data to be obtained, reprocessed, integrated, optionally transformed, modelled and finally interpreted in order to understand the underlying process. This procedure is affected by both objective and subjective uncertainties. In parallel with the development of geostatistics, the role of uncertainty has been widely investigated in geosciences. This has led to the introduction of new concepts, taken for example from thermodynamics, such as entropy. Predicting the subsurface is an especially thankless effort, as data are driven from spatially highly limited direct sources. The following paper provides an review of various applications of the Shannon entropy theorem in geoscience. Information entropy, initially proposed by Shannon (1948) provides an objective measure of overall system uncertainty. Significant concern has been focused on the application of Shannon entropy to provide an objective measure of joint system uncertainty and visualization of its spatial distribution. The area of extensively drilled Eocene amber-bearing deposits located in the Lubelskie voivodeship was selected as a case study to investigate the quality of prediction stochastic lithofacies models. The importance of adding secondary variables to a stochastic model is also reviewed here. Adding new data and rerunning the simulation allows assessment of its impact on the predictability of a stochastic model. The most important conclusion from the study is that the deposition of amber-bearing lithofacies occurred mostly in the northern part of the area investigated, as shown also by ongoing exploitation of the deposit.

Opis:

Upper Silurian and Lower Devonian shelf deposits in West Bulgaria are exposed in three main Alpine tectonic units: the West Balkan Unit, the Lyubash Monocline and the Morava Unit. The West Balkan and Lyubash units consist of siliciclastic deposits: black graptolitic shales, banded pale shales and black siltstones. The Ludlow, Pridoli, Lochkovian, Pragian and Emsian were recognized on the basis of graptolite and tentaculite faunas. In the Morava Unit, the Ludlow black shales are progressively replaced by clayey limestones and nodular and micritic limestones in the Pridoli and Early Devonian. Newly obtained conodonts show the presence of the siluricus, eosteinhornensis, woschmidti, postwoschmidti, delta-pesavis, sulcatus, dehiscens and gronbergi zones. Petrographic study of the Morava Unit shows an increasing carbonate content and shallowing conditions upwards. The biostratigraphical correlation and facies interpretation reveal the coeval existence of two different depositional environments within the same shelf basin as well as a gradual shift in proximal direction.

Opis:

The Flow Zone Index, FZI, applied to order relations between the effective porosity and permeability of the Rotliegend sandstones in the Polish part of the Southern Permian Basin turns out to be a useful and effective factor to evaluate ability of media flow in a rock formation. A dataset of over 2000 samples from 78 wells was analysed. Based only on porosity and permeability, FZI includes all non-parameterized features of rocks as tortuosity and diameters of porous channels, volume of trapped parts of capillary roads, specific surface of pore space, and others. When FZI increases, the ability of fluid to move through the porous space increases. In most cases, the Rotliegend sandstones reveal FZI in the range of 0.5-2.0. The highest FZI, ca. 100, is related to fractured part of the studied formation. The combination of FZI and facies information from several wells in the study area (over 1200 samples) showed a good correlation. On the basis of FZI we can divide a set of samples of the Rotliegend sandstone into groups of defined fluid flow abilities and relate them to facies. Also, we show the way of estimation of the reliable values of permeability in full geological log of a borehole on the basis of FZI, and the total porosity determined from well logging interpretation.

Opis:

Three broad lithofacies – bioturbated packstone- to rudstone, calcareous sandstone and cross-bedded rudstone to packstone are recognized within the Jajiya Member. The facies architecture and stalking pattern suggests deposition related to TST, HST and TST events punctuated by MFZ events in sequence stratigraphic terms. The 11.4 m thick sequence represents two fining upward and three coarsening upward cycles representing bar-bank depositional settings. The framework constituents of these facies were mainly controlled by the depositional conditions through space and time and have greatly influenced their diagenetic evolution. The main diagenetic features observed within the facies include compaction, early cementation and porosity reduction, micritization and neomorphism representing early or syn-depositional and post-depositional changes. Two phases of early mechanical compaction have largely governed porosity development in these facies. However, cementation, micritization and neomorphism have also contributed significantly in this respect. Evidence suggests that marine phreatic and fresh water phreatic environments dominated the diagenetic evolution of these facies. Calcite cementation was first formed, followed by iron oxide, while silica cementation occurred probably at a late stage.

Opis:

This study reports on the occurrence of tektite clasts with a markedly different degree of abrasion in two different fluvial facies of the Pleistocene deposits of the Nysa Kłodzka river near Paczków, SW Poland. The question addressed by the study is whether the redeposited and differently abraded tektite glass clasts derive from different distances/sources, or whether their differing degree of abrasion relates to their different host sediment as the medium of river bedload transport. Laboratory tumbling experiments are used to estimate the progress of tektite abrasion with the distance travelled within a bedload sediment of the corresponding grain-size composition. The study concludes that there is a direct relationship between the abrasion degree of tektites and their host sediment facies, but it is not simple and straight forward, as a range of specific factors comes potentially into play. Their role is discussed and is recommended to be taken into account in an abrasion experiment design and in the interpretation of experimental results. The study suggests that the tektite clasts found near Paczków were transported over a distance of about 2-4 km and were derived from denudation of the nearby Bardzkie Mts.

Opis:

3D seismic data and wireline logs from thirteen boreholes were used to establish a sequence stratigraphic analysis of Miocene depositional systems of the Otu Field in the onshore area of the Niger Delta. The subsurface facies of the field revealed three sequences that are bounded by four sequence boundaries (SBs) which are interpreted as erosional unconformities with three maximum flooding surfaces (MFSs). Sequences delineated are composed of lowstand systems tracts (LST), falling stage systems tracts (FSST), transgressive systems tracts (TST) and highstand systems tracts (HST) revealing depositional systems deposited during different phases of base level changes. Deposits identified within the LSTs are fluvial channel sands while TSTs capped the LST facies. HSTs are composed of coarsening and shallowing upwards intervals including deltaic fluvial sands. The sequences were deposited in transitional to shallow marine environments. A seismic geomorphological study carried out on all the SBs and MFS 3 shows a relationship between depositional environments, channel type and direction of palaeo-flow in relation to faults. The reservoirs of the LST and HST and seals from marine shale of the TST and HST could form stratigraphic traps for hydrocarbon accumulation in the Otu Field. This study has integrated 3D seismic and borehole log data to develop a sequence stratigraphic framework that would be a profitable means to guide hydrocarbon exploration and production strategies.

Opis:

We review the three regional anastomosing fluvial systems, both ancient and modern. The dinosaur-bearing upper Triassic succession in Krasiejów (S Poland) is composed of siltstones and claystones that are divided into three facies associations. One of the fluvial associations is characterized by features typical of a low-energy anastomosing river system in a tropical semiarid climate, interpreted as the result of accumulation in deep, wide and low-sinuosity palaeochannels with pronounced vertical accretion. Deposition from suspension predominated in flows of very low stream power. The upper Neogene muddy succession in a tectonically active area (Kleczew Graben, central Poland) includes a great number of fluvial palaeochannels filled with sand and/or mud. These ribbon-shaped fluvial bodies are deep and wide, and represent channels showing very lim ited lateral migration. They were filled mostly under low-energy condi tions, and their mapped course shows an “anabranching” pattern in plan view. The palaeochannels are transitional from sand- to mud-dominated. The Holocene upper Narew River (NE Poland) represents a modern anastomosing fluvial system. The interconnected channels form an anabranching pattern. The channels are straight to slightly sinuous, relatively deep and wide. Interchannel, low-lying “islands” are covered by peat-forming plants. Despite the low stream power, in-channel deposition is dominated by sand transported as bedload. The channel banks are stabilised by vegetation, which effectively prevents their lateral migration.

Opis:

This paper provides a synthetic sedimentological overview of themiddle Frasnian carbonate platform of Belgium and associated carbonate mounds. Carbonate mounds started usually in a relatively deep, quiet subphotic environment with a crinoid-coral-sponge assemblage, then reached the fair-weather wave base and the euphotic zone with an algal-microbial facies. The upper parts of themounds are characterised by lateral facies differentiation with the algal-microbial facies protecting a central sedimentation area with a dendroid stromatoporoids facies and fenestral limestone. The lateral facies reflect different kinds of input of reworked mound material in the proximal area, from transported fine-grained sediment to coarse-grained fossil debris. On the platform, environments range from the outer zone (crinoidal facies) to stromatoporoid-dominated biostromes and to the lagoonal area of the inner zones (subtidal facies with Amphipora floatstone, algal packstone, intertidal mudstone and laminated peloidal packstone and palaeosols). These facies are stacked in metre-scale shallowing-upward cycles. The larger scale sequential organisation corresponds to transgressions and regressions, whose cycles are responsible for differentiating a lower open-marine biostrome dominated unit from an upper lagoonal unit. The last regression- transgression cycle, responsible for the platform-scale development of lagoonal facies, can be correlated with an atoll-stage evolution of the carbonate mounds belonging to the Lion Member.

Opis:

The Lower - lowermost Upper Jurassic (up to Oxfordian) sedimentary succession of the Jaisalmer Basin on the Rajasthan Shelf is characterized by gradual lateral and rapid temporal facies variations, the existence of condensed sequences in certain horizons, and rich and highly diverse faunal contents. Lithostratigraphically, these Jurassic rocks of the basin have been grouped into the Lathi and Jaisalmer formations and the lower part of the Baisakhi Formation. The facies consist of (i) cross-bedded medium- to coarse-grained sandstone, (ii) cross-bedded to thinly laminated silt to fine-grained sandstone, (iii) silty marl, (iv) calcareous mud- to grainstone and sandy rudstone, (v) thinly laminated carbonaceous shale and (vi) conglomerate. These represent fluvial, floodplain, lacustrine, protected marginal marine, and shoreface to shelf environments. There are several marker units, which allow the making of intrabasinal lithostratigraphic correlations; however, a lack of knowledge of the detailed stratigraphic successions within individual lithostratigraphic units makes difficult a precise intra-basinal stratigraphic correlation. The present review provides a summary of the lithostratigraphy established by previous workers on the Lower - lowermost Upper Jurassic (up to Oxfordian) rocks of the Jaisalmer Basin, incorporating additional data, with a detailed stratigraphic succession within each lithostratigraphic unit, and more faunal elements recently.

Opis:

Middle Triassic deposits in the Velebit Mts. of the External Dinarides in Croatia show strong differentiation of sedimentary environments and facies. In the area of Donje Pazarište, a 90 metre thick section includes six different facies, each with its specific genetic characteristics (Flysch-like Facies; Carbonate Shale Facies; Pyroclastic Density Current Facies; Platy Limestone with Pyroclastics Facies; Limestone Breccia Facies and Slumped Limestones with Pyroclastics and Chert Facies). In the same area, in the nearby Top of Donje Pazarište section, a Pyroclastic Flow Facies was defined, and this was also recognized ~15 km to south-east, in the area of Brušane Village, in the foothills of Vinac. Throughout the area and section investigated, the effects of intense tectonic and volcanic activity can be traced. The pronounced differences in the facies determined facies are interpreted as consequences of syntectonic and volcanically influenced sedimentation in a graben/half-graben depositional system.

Opis:

Detailed lithostratigraphic data from a borehole in the Abrămuţ Basin, located in the northwestern part of Romania, has revealed the presence of turbiditic deposits containing several layers with tuff/tuffaceous materials in the lower Badenian. The age of these deposits is determined by the presence of the foraminifera Praeorbulina glomerosa and Orbulina suturalis. Detailed quantitative and qualitative X-ray diffraction data (XRD) on 10 different tuff layers situated at depths between 2450 and 2640 m show a mineralogical association comprising analcime, quartz, volcanic glass, smectite, mica, calcite, K-feldspar, glass and minor quantity of chlorite and albite. The presence of analcime suggests that the albite isograd for the interval studied has been never reached and the maximum temperatures have been lower than c. 125degrees C since the early Badenian.

The last Weichselian glacial advance into the western Baltic depression, the so-called "Young Baltic" glacier advance is described. In the southern Baltic depression, ice masses flowed westwards and fanned out in the western Baltic region where they terminated along the end moraines of the East Jutland advance (Denmark), Sehberg advance (Schleswig-Holstein) and Mecklenburg advance (Mecklenburg-Vorpommern). The westward ice advance is likely due to the rapid melting of Norwegian and Swedish ice masses which had previously blocked the more easterly ice masses from draining to the west and north-west. The deposition of a purely eastern-sourced debris facies by a Baltic ice stream in the far west might be the result of ice/bed separation during flow.

Opis:

Badenian evaporites of the Carpathian Foredeep Basin represent the lower part of the NN6 zone and are underlain and overlain by deep-water deposits. Halite and associated deposits in the central part of the Badenian evaporite basin show the same facies successions and marker beds can be traced across and between individual basins. Characteristic marker beds made it possible to correlate various facies zones of the marginal Ca-sulfate platform. These marker beds seem to reflect events that may be related to sudden and widespread changes in water chemistry, which in turn imply major changes in basin hydrology. The onset of the evaporitic deposition in the Carpathian Foredeep was clearly diachronous and the evaporites deposited in the basin centre preceded the beginning of evaporite sedimentation in the marginal basin, however, depositional history in the marginal basin and the basin center was the same. Sedimentological and geochemical data indicate recycling of evaporites throughout most of the evaporite deposition.

Opis:

The Bravaisberget Formation of southern Spitsbergen (the youngest formation of the Sassendalen Group; Middle Triassic–Carnian) comprises a succession of organic-rich and sandy phosphogenic deposits that developed in a marginal part of the Svalbard basin, in response to a high biological productivity event in the Barents Shelf. The basin margin was bounded on the southwest by the elevated structure of the Sørkapp-Hornsund High. North of the high, the subsiding shelf bottom stretched from southern to western Spitsbergen. The organic-rich, fine-grained sedimentation that gave rise to the formation of the Passhatten Member extended southward after the Anisian transgression; it reached the topmost part of the Sørkapp -Hornsund High during the maximum flooding of the basin in the early Ladinian. The sudden appearance of deltaic deposits of the Karentoppen Member directly after the maximum flooding was a consequence of short-lived tectonic activity of the Sørkapp -Hornsund High and the adjacent land area. Reworking and redistribution of the deltaic sediments during the Ladinian brought about the formation of shallow-marine clastic facies of the Somovbreen Member. Decreasing depositional rates close to the Middle-Late Triassic boundary led to a regional hiatus and the formation of a condensed phosphorite horizon at the top of the Somovbreen Member. The sedimentation of the Bravaisberget Formation ended in the early Carnian. The youngest siliciclastic and spiculitic sediments of the Van Keulenfjorden Member were deposited in southern and western Spitsbergen in shallow- to marginal-marine environments.

Opis:

Twenty groundwater samples were collected and then examined for physical (pH, EC, TDS) and chemical (Na+, K+, Ca2+, Mg2+, HCO3−, Cl−, SO42−, NO3) parameters, followed by multivariate statistics to determine the current state of groundwater quality and to assess the suitability of these resources for drinking and irrigation purposes in the Baser Sakhra area localized in Eastern of Algeria. The analysis carried out showed that the cations trend in most of the groundwater samples is on the order of Ca2+˃Na+˃Mg2+˃K+ and the anions trend is on the order of HCO3-˃SO42-˃Cl-. Stabler diagram demonstrated the predominance of Ca2+- HCO3- hydro-chemical facies (80%). Moreover, the parameters, such as sodium adsorption ratio, percentage sodium, residual sodium carbonate, permeability index, Kelly’s ratio, potential salinity, and magnesium hazard were evaluated for the suitability of groundwater for irrigation. The values obtained in this investigation concluded that most of the groundwater samples are suitable for irrigation. From the other approach, the Water Quality Index (WQI) for drinking was also used in the current study. WQI ranged from 72.46 to 506.426, indicating that 40% of the samples were suitable for drinking however, 60% of them belong to the poor to unsuitable category of drinking water in terms of physicochemical properties, according to the World Health Organization norms.

Opis:

New conodont data provide further constraints on the occurrence of the Devonian-Carboniferous boundary in the Kule section through the carbonate Novchomok Formation (Kitab Reserve, Uzbekistan). The stratigraphically condensed section includes the interval from the uppermost Famennian Pseudopolygnathus granulosus–lowermost Protognathodus kockeli zones to the middle Tournaisian Siphonodella crenulata Zone. In addition to revision of earlier published taxonomic and biostratigraphic data, two previously unreported taxa are described: Polygnathus sp. n. A and a peculiar form probably representing a new genus (gen. et sp. indet.). The biofacies analysis documents a succession of polygnathid, siphonodellid-polygnathid, polygnathid-siphonodellid to polygnathid-bispathodid, and again polygnathid-siphonodellid biofacies. The generic composition of the samples and relative abundance of Polygnathus purus reflect deep marine environments of the continental slope and rise.

Opis:

A diverse fauna of helcionelloid molluscs, hyoliths, and other small shelly fossils is described from limestone layers within the Forteau Formation of the Bonne Bay region in western Newfoundland. The fauna is dominated by internal moulds of various molluscs and tubular problematica, but also includes hyolith opercula, echinoderm ossicles, and other calcareous small shelly fossils preserved by phosphatisation. Originally organophosphatic shells are comparatively rare, but are represented by brachiopods, hyolithelminths, and tommotiids. The fauna is similar to other late Early Cambrian faunas from slope and outer shelf settings along the eastern margin of Laurentia and may be of middle Dyeran age. The similarity of these faunas indicates that at least by the late Early Cambrian, a distinctive and laterally continuous outer shelf fauna had evolved. The Forteau Formation also shares elements with faunas from other Early Cambrian provinces, strengthening ties between Laurentia and Australia, China, and Europe during the late Early Cambrian. Two new taxa of problematic fossil organisms are described, the conical Clavitella curvata gen. et sp. nov. and the wedge−shaped Sphenopteron boomerang gen. et sp. nov.

Opis:

This sedimentological study was based on well cores from the Polish and Ukrainian parts of the Carpa- thian Foredeep. It revealed general heterogeneity of facies in the middle Miocene of the sedimentary succession in the basin. Fourteen sedimentary facies were distinguished and their origin was interpreted: massive, non-graded sandstones; normal-graded, massive sandstones, with and without a stratified uppermost part; hydroplastically deformed sandstones; planar-parallel-stratified sandstones; trough-cross-stratified sandstones; ripple-cross-lami- nated sandstones; heterolithic deposits, composed of thinly interlayered sandstone and mudstone; massive and laminated mudstones; and basal gypsum/anhydrite evaporites, often intercalated with mudstone. Four main modalities of vertical facies organization were recognized and attributed to the following environments: (1) the mid-late Badenian, shoal-water, evaporitic environment that preceded the latest Badenian–early Sarmatian, main phase of foredeep development; (2) a littoral, tidal environment of the inner parts of storm-influenced, coastal bays and tidal flats or possibly spit-sheltered lagoons; (3) a wave-dominated, littoral, sandy environment, considered to be shoreface, extended by waves, in front of advancing deltas; and (4) a neritic to subneritic, muddy, offshore slope, characterized by frequent incursions of tempestite and turbidite sand. The study contributed to a better understanding of the mid-Miocene depositional systems in the basin, with significant implications for ongoing hydrocarbon exploration. Interpretations of the origins of potential reservoir sandstones provided important information on their possible stratigraphic distribution in the basin fill. The potential, economic importance of stratigraphic hydrocarbon traps underscored the urgent need for a full-scale facies analysis and fully cored wells in strategic parts of the basin.

Opis:

This study from the Sremski Karlovci clay pit in northern Serbia sheds new light on the physicochemical conditions, ecology and evolution of the Paludina Lake – the Pliocene successor of the late Miocene giant Lake Pannon hosted by the Pannonian Basin. The multidisciplinary study combines sedimentology, sequence stratigraphy, biostratigraphy, palaeontology, palaeobotany, coal petrology, organic geochemistry and magnetic mineralogy. The sedimentary succession studied represents the lake margin at the foot of the Fruška Gora ridge. Sedimentary facies reveal minor and major lake-level changes, including a forced regression with fluvial valley incision in the succession middle part and the ultimate emergence and covering of the lake floor by Pleistocene loess. Mollusc and ostracod fauna indicates an oligohaline shallow cool-water environment, no deeper than 5–6 m, with an active inflow of spring water. The lake local depth during transgression maxima did not exceed 20 m. Palynological and geochemical analyses indicate a rich and diversified assemblage of gymnosperm plants with a contribution of angiosperms, weeds and microbial biomass in the peat-forming suboxic to oxic coastal swamp environment. Maceral analysis of organic matter shows a prevalence of huminite, accompanied richly by inertinite in lignite and by liptinite in clay. The Pleistocene shift to terrestrial semiarid environment resulted in oxidizing groundwater conditions, with the reddening of sediments around a fluctuating groundwater table and the diagenetic transformation of bacteria-derived greigite into magnetite. In regional stratigraphy, the occurrence of Viviparus neumayri Brusina in the lower half of the succession indicates the Lower Paludina Beds of Dacian Stage (early Zanclean age). Other gastropods and certain ostracodes indicate transition to the Middle Paludina Beds of lower Romanian Stage (late Zanclean–early Piacenzian). The upper half of the succession lacks age-diagnostic fossils and is considered to represent Middle Paludina Beds with a possible relic of Upper Paludina Beds at the top.

Opis:

Limestones designated the Štramberk-type are the most common carbonate exotic clasts (exotics) embedded in the uppermost Jurassic–Miocene flysch deposits of the Polish Outer Carpathians. About 80% of stratigraphically determinable carbonate exotics from the Silesian, Sub-Silesian and Skole units (nappes) are of Tithonian (mostly)–Berriasian (sporadically Valanginian) age. A study of these exotics revealed eight main facies types: coral-microbial boundstones (FT 1), microencruster-microbial-cement boundstones (FT 2), microbial and microbial-sponge boundstones (FT 3), detrital limestones (FT 4), foraminiferal-algal limestones (FT 5), peloidalbioclastic limestones (FT 6), ooid grainstones (FT 7), and mudstones-wackestones with calpionellids (FT 8). Štramberk-type limestones in Poland and the better known Štramberk Limestone in the Czech Republic are remnants of lost carbonate platforms, collectively designated the Štramberk Carbonate Platform. Narrow platforms were developed on intra-basinal, structural highs (some of them are generalized as the Silesian Ridge), with their morphology determined by Late Jurassic synsedimentary tectonics. An attempt was made to reconstruct the facies distribution on the Tithonian–earliest Cretaceous carbonate platform. In the inner platform, coral-microbial patch-reefs (FT 1) grew, while the upper slope of the platform was the depositional setting for the microencruster-microbial-cement boundstones (FT 2). Microbial and microbial-sponge boundstones (FT 3), analogous to the Oxfordian–Kimmeridgian boundstones of the northern Tethyan shelf (also present among exotics), were developed in a deeper setting. In the inner, open part of the platform, foraminiferal-algal limestones (FT 5) and peloidal-bioclastic limestones (FT 6) were deposited. Poorly sorted, detrital limestones (FT 4), including clastsupported breccias, were formed mainly in a peri-reefal environment and on the margin of the platform, in a high-energy setting. Ooid grainstones (FT 7), rarely represented in the exotics, were formed on the platform margin. Mudstones-wackestones with calpionellids (FT 8) were deposited in a deeper part of the platform slope and/or in a basinal setting. In tectonic grabens, between ridges with attached carbonate platforms, sedimentation of the pelagic (analogous to FT 8) and allodapic (“pre-flysch”) Cieszyn Limestone Formation took place. The most common facies are FT 4 and FT 1. Sedimentation on the Štramberk Carbonate Platform terminated in the earliest Cretaceous, when the platform was destroyed and drowned. It is recorded in a few exotics as thin, neptunian dykes (and large dykes in the Štramberk Limestone), filled with dark, deep-water limestones. Reefal facies of the Štramberk Carbonate Platform share similarities in several respects (e.g., the presence of the microencrustermicrobial-cement boundstones) with reefs of other intra-Tethyan carbonate platforms, but clearly differ from palaeogeographically close reefs and coral-bearing facies of the epicontinental Tethyan shelf (e.g., coeval limestones from the subsurface of the Carpathian Foredeep and the Lublin Upland in Poland; the Ernstbrunn Limestone in Austria and Czech Republic). Corals in the Štramberk Limestone and Štramberk-type limestones are the world’s most diverse coral assemblages of the Jurassic–Cretaceous transition. The intra-basinal ridge (ridges), traditionally called the Silesian Cordillera, which evolved through time from an emerged part of the Upper Silesian Massif to an accretionary prism, formed the most important provenance area for carbonate exotic clasts in the flysch of the Silesian Series. They are especially common in the Lower Cretaceous Hradiště Formation and the Upper Cretaceous–Paleocene Istebna Formation. The Baška-Inwałd 204 M. HOFFMANN Et Al. In the Polish Outer Carpathians, shallow-water carbonate sedimentation is recorded only by carbonate clasts, redeposited bioclasts, and very rare, small, unrooted, poorly exposed klippen. Clasts of limestones are exotic to the dominant siliciclastic, uppermost Jurassic–Miocene flysch deposits. They were derived from extrabasinal and intra-basinal source areas of the Carpathian rocks, which periodically emerged and were destroyed. Such rocks were described as “exotic” since the 19th century (“exotischen Graniten”, “exotische Blöcke”; Morlot, 1847; Hohenegger, 1861). In the general geological literature, the term “exotic clasts” is usually used (Flügel, 2010, p. 172), whereas in the Polish geological literature, the term “exotics” (Polish “egzotyki” including also carbonate exotics), is also commonly applied. On the basis of fossils, facies and microfacies, these clasts (pebbles, rarely blocks) are mostly described as Devonian–Carboniferous (Malik, 1978, 1979; Burtan et al., 1983; Tomaś et al., 2004) and Upper Jurassic–lowermost Cretaceous (the present paper and references therein), more rarely Middle Jurassic (Książkiewicz, 1935, 1956a; Barczyk, 1998; Olszewska and Wieczorek, 2001), Early Cretaceous (Oszczypko et al., 1992, 2006, 2020; Krobicki et al., 2005), Late Cretaceous (Książkiewicz, 1956a; Gasiński, 1998) and Palaeogene in age (Leszczyński, 1978; Rajchel and Myszkowska, 1998; Leszczyński et al., 2012; Minor-Wróblewska, 2017). At the beginning of these studies, the focus was on small, unrooted klippen, namely the Andrychów Klippen (called also Klippes) near Wadowice (Zeuschner, 1849; Hohenegger, 1861; Uhlig, 1904; Książkiewicz, 1935, 1971b; Nowak, 1976; Gasiński, 1998; Olszewska and Wieczorek, 2001), and in Kruhel Wielki, near Przemyśl (Niedźwiedzki, 1876; Wójcik, 1907, 1913, 1914; Bukowy and Geroch, 1956; Morycowa, 1988; Olszewska et al., 2009), now poorly exposed. Subsequently, exotic pebbles, much more common and providing data on more facies, were studied more frequently. The first attempt to describe exotics, including crystalline rocks, was presented by Nowak (1927). Jurassic–Cretaceous carbonate exotics at Bachowice, containing facies unknown at other localities in the Polish Outer Carpathians, were described by Książkiewicz (1956a). The preliminary results of studies, which encompassed the entire spectrum of carbonate exotics from the western part of the Polish Outer Carpathians, were presented by Burtan et al. (1984). Malik (1978, 1979) described both Palaeozoic and Mesozoic carbonate clasts in the Hradiště Sandstone of the Silesian Unit, but other studies were mostly concerned with the Štramberk-type limestones from selected outcrops. The studies of these limestones, if concerned with exotics at many localities, were focused on their fossil content (e.g., Kołodziej, 2003a; Bucur et al., 2005; Ivanova and Kołodziej, 2010; Kowal-Kasprzyk, 2014, 2018) or presented only the preliminary results of facies studies (e.g., Hoffmann and Kołodziej, 2008; Hoffmann et al., 2008). Carbonate platforms, the existence of which was deciphered from detrital carbonate components, are called lost carbonate platforms (e.g., Belka et al., 1996; Flügel, 2010; Kukoč et al., 2012). Clasts and other shallowwater components are, metaphorically, witnesses to lost carbonate factories (the term is taken from Coletti et al., 2015). Analyses of the age and lithology of exotic clasts have been applied in the reconstruction of the provenance areas of the clasts and their palaeogeography and the development of the sedimentary sequences of the Polish Outer Carpathians (e.g., Książkiewicz, 1956b, 1962, 1965; Unrug, 1968; Oszczypko, 1975; Oszczypko et al., 1992, 2006; Hoffmann, 2001; Krobicki, 2004; Słomka et al., 2004; Malata et al., 2006; Poprawa and Malata, 2006; Poprawa et al., 2006a, b; Strzeboński et al., 2017; Kowal-Kasprzyk et al., 2020). Štramberk-type limestones are most common among the exotics. It is a field term that refers to limestones, mostly beige in colour, that are supposed to be the age and facies equivalents of the Tithonian–lower Berriasian Štramberk Limestone in Moravia (Czech Republic; Eliáš and Eliášová, 1984; Picha et al., 2006). The Štramberk Limestone and the Štramberk-type limestones of both countries were deposited on platforms, attached to the intrabasinal ridges and margins of the basin of the Outer Carpathians. These platforms are collectively termed the Štramberk Carbonate Platform. The terms “Štramberk Limestone” and “Štramberk-type limestones” have been widely used in the area of the former Austro-Hungarian Empire for the field description of shallow-water limestones of assumed Late Jurassic age, usually occurring within flysch deposits of the Outer Carpathians. Upper Jurassic–lowermost Cretaceous shallow-water limestones in Romania (commonly forming mountains or ridges, e.g., Pleş et al., 2013, 2016), in Bulgaria and Serbia (Tchoumatchenco et al., 2006), and Ukraine (Krajewski and Schlagintweit, 2018), and in Turkey (Masse et al., 2015) sometimes are referred to as the Štramberk-type limestones as well. In the Austrian-German literature similar limestones in the Alps are known as the Plassen Limestone (e.g., Steiger and Wurm, 1980; Schlagintweit et al., 2005). Biostratigraphic studies revealed that some carbonate clasts, accounting for several percent of the exotics and commonly Ridge and the Sub-Silesian Ridge were the source areas for clasts from the Silesian and Sub-Silesian units (e.g., in the Hradiště Formation), while the Northern (Marginal) Ridge was the source for clasts from the Skole Unit (e.g., in the Maastrichtian–Paleocene Ropianka Formation).

Opis:

GPR method is perfectly suited for recognizing of sedimentary facies diversity in shallowly occurring sediments if there is a contrast of electrical properties between and/or within each layer. The article deals with the issue of the correlation between GPR surveys results and sedimentological analyses. As a result of this correlation a conceptual model of depositional systems of studied areas was developed. Studies were performed in two areas located in central Poland, where glacial deposits formed in the Middle Polish (Saalian) Glaciation are present. The study was based on 49 sediment samples and 21 GPR profiles. Analyses of lithofacies as well as granulometric and mineralogical composition of deposits of collected samples were carried out, showing the diversity of glacial deposits in both study sites. During GPR measurements shielded antenna with a frequency of 500 MHz was used which allowed high-resolution mapping of the internal structure of deposits and to identify four characteristic radar facies. Correlation of GPR profiles with point, one-dimensional sedimentological studies allowed the unambiguous interpretation of the GPR image and draw conclusions about the formation environment of individual units. Geophysical and sedimentological data obtained during study provide a new and detailed insight into selected glacial deposits in central Poland.

Opis:

The Zechstein Limestone of the Bonikowo 2 borehole is composed of limestone with varied dolomite content and is slightly thicker (3.4 m) than other supposed condensed sections in SW Poland. The microfacies (mostly bioclastic wackestones-packstones) are characteristic of open marine limestone deposited in deep shelf environments. The common occurrence of echinoids in all parts of the section, except close to its top, indicates no essential change in sea water salinity. However, the palaeotemperature interpretation of the highest δ18O value of calcite recorded in the Bonikowo 2 borehole (+0.32‰) indicates a temperature of 22.9°C when a δ18O of water = 2‰ is assumed. The δ13C and δ18O curves for calcite and dolomite are similar in shape, and their mean values are similar: +1.8 ±1.5‰ for calcite, respectively, and +1.9 ±2.3‰ and –4.3 ±2.4‰, –3.8 ±4.3‰ for dolomite. There is a recrystallized interval in the lower part of the section with both δ13C and δ18O values reduced. This may be regarded as an aerobic equivalent of the Kupferschiefer. The diversity and abundance of foraminifers is significant throughout the section studied; lagenids prevail, and this is considered to be due to the dysaerobic conditions throughout the duration of deposition of the Zechstein Limestone.

Opis:

The entrenched Odra palaeovalley, cut into the bedrock of the distal margin (forebulge basal unconformity) of the Moravian Carpathian Foredeep (peripheral foreland basin) is filled with an almost 300 m thick pile of Miocene deposits. The directon of the valley (NW-SE to NNW-SSE) has been controlled by faults subparallel with the system of “sudetic faults“. The sedimentary succession consists of 5 facies associations/depositional environments, which are interpreted (from bottom to top, i.e. from the oldest to the youngest) as: 1 - colluvial deposits to deposits of alluvial fan, 2 - deposits of alluvial fan, 3 - fan-delta deposits, 4 - shallow water delta to nearshore deposits and 5 - open marine deposits. This fining-up and deepening-up succession reveals the following: the formation of the new flexural shape of the basin; deep erosion connected with uplift and tilting of the forebulge and reactivation of the NW-SE trending basement faults; the Early/Middle Miocene sea level fall; alluvial deposition mostly driven by tectonics and morphology; forebulge flexural retreat; Middle-Miocene sea level rise; back-stepping of valley infill; marine invasion during the Early Badenian with shift of the coastline further landward of the pallaeovalley. Tectonics related to contemporary thrusting processes in the Western Carpathians are assumed to be the dominating factor of the studied deposition at the expense of eustatic sea level changes. Provenance studies have proven that the pre-Neogene basement (i.e. the Early Carboniferous clastic “Culmian facies” ofthe Moravian-Silesian Paleozoic) represents an important source for the conglomerates and sands, which volumetrically dominate in the palaeovalley infill. However, they also showed, that the deposits of the earlier Carpathian Foredeep Basin sedimentary stage (Karpatian in age?) covered the area under study and were eroded and resedimented into the palaeovalley infill.

Opis:

Hornfelsy pochodzące z wyrobisk dawnej kopalni „Wolność” w Kowarach na Dolnym Śląsku są to skały wchodzące w skład formacji rudonośnej z Podgórza. Struktura ta znajduje się na styku granitoidowego masywu Karkonoszy oraz jego wschodniej osłony metamorficznej. Zmienność składu mineralnego badanych hornfelsów, a także ich cech strukturalno-teksturalnych były podstawą wydzielenia odmian barwnych tych skał, tj. czarnej, szarej i zielonej. Każda z nich występuje niezależnie, bądź też wzajemnie się przeławicają, dając odmiany mieszane o teksturach laminowanych lub smużystych. Na podstawie składu mineralnego stwierdzono, że hornfelsy z Kowar należą do facji piroksenowo-hornfelsowej metamorfizmu kontaktowego, dla której charakterystyczny jest następujący zespół mineralny: pirokseny, plagioklazy i kwarc; muskowit jest zastępowany ortoklazem, a biotyt pozostaje stabilny. Typowym minerałem tej facji jest andaluzyt, choć niekiedy może występować również sillimanit. W skałach tych wyróżniono przynajmniej trzy generacje faz mineralnych: I – allogeniczną, II – metamorficzną i III – hydrotermalną. [...]
Hornfels from the closed “Wolność” mine (Kowary, the Lower Silesia) are recognized as thermally metamorphosed rocks belonging to hornblende-hornfels facies or locally a facies of pyroxene hornfels. Their texture reveal the traces of some deformations such as folding or fractures. Their protholit is described as a pelitic deposit enriched with clay minerals. The sediment was altered into meta-pelities-aleurites after the diagenesis, and later the rock was intensely thermally metamorphosed at the contact with the intrusion of the Karkonosze granitoid. Three varieties are distinguished based on their colour: green, grey and black. Green and black colours result from the predominance of hornblende and biotite over other rock components, respectively. Whereas grey hornfels are composed of similar amounts of both mafic minerals: biotite and hornblende. Quartz, mica minerals (biotite and muscovite), amphibole, (hornblende), acid plagioclase and andalusite, epidote group (clinozoisite), orthoclase and pyroxene make up hornfels components. Locally, andalusite is accompanied by sillimianite, which indicates a higher degree of contact metamorphism alterations. Three generations of minerals are distinguished in the rocks: allogenic (I), metamorphic (II ) and hydrothermal (III ). The allogenic phases are represented by heavy minerals such as zircon, apatite and monazite, which are characteristic of the protholit. The main components of the rocks (e.g. quartz, hornblende, feldspars, andalusite, sillimanite, mica minerals) belong to metamorphic minerals. Chalcopyrite, pyrite and fluorite are surely hydrothermally originated phases. Granitoides found at the contact zone with hornfels indicate traces of metasomatic alteration as a result of endomorphism in this region.

Opis:

Numerous fully cored boreholes completed in the last years in central Poland (Kleszczów Graben area, southern border of the Łódź Depression) enabled the researchers to obtain new sedimentological data on the Oxfordian-Tithonian continuous sedimentary record in the Polish part of the northern Tethys shelf. Twenty-two facies were distinguished in the sedimentological succession. The facies represent the outer-, mid- and inner-ramp environments, including evaporitic episodes and palaeosols. The facies document that the Oxfordian-Lower Kimmeridgian (up to Hypselocyclum) carbonate ramp has evolved to the Upper Kimmeridgian-Tithonian carbonate-siliciclastic ramp. Among the Kimmeridgian deposits, numerous hardgrounds, tidal channel deposits and gravity flow sediments were identified. The Kleszczów Graben sedimentary succession is discussed along with the lithostratigraphical units known from the adjacent regions of southern and central Poland.

Opis:

The anisotropy of magnetic susceptibility (AMS) of sedimentary rocks has been used for interpreting wide range of processes: early rock deformations, palaeotransport directions, as well as the evolution of mineral content. Various sedimentary factors which may determine magnetic susceptibility within lacustrine, river, floodplain and swamp deposits have been examined in the Oravica section of the Orava-Nowy Targ Basin. Multiple components of mineral content: illite, chlorite, smectite, kaolinite, quartz and unidentified high susceptibility phase make an AMS interpretation of this content ambiguous. However, this method may be useful for tracing early diagenetic geochemical/microbial processes where iron element is involved. Some sedimentary processes may be recognized from AMS when an assemblage of parameters is studied together: bulk susceptibility, the degree and the shape of anisotropy, principal directions, and the distribution of all these parameters within a set of specimens. Debris-flow processes, as well as lacustrine and floodplain sedimentation are especially well-defined in AMS results. Palaeotransport directions are ambiguous because studied rocks have undergone weak deformation what overprints this sedimentary feature. Most specimens represent an oblate shape of anisotropy and show a good correlation of minimum susceptibility axis and normal to bedding plane.

Opis:

Coral facies developed on the Middle Oxfordian carbonate ramp were controlled in the region of Bałtów, NE margin of the Holy Cross Mts., Poland, by syndepositional activity of extensional fault blocks. Elevated parts of sea bottom were occupied since Early Oxfordian time by sponge bioherms successively colonized by coral reefs when grown up to the sea level. Micritic sedimentation prevailed in interbioherm denivelations. This micritic succession was replaced by soft-bottom coral buildups constructed by flat coral colonies, typical of a relatively quiet environment of the depths 20-70 m, and finally by coarse bioclastic grainstones and oncolites which are interpreted as talus of the coral reef constructed on tops of former sponge bioherms by branched and hemispherical coral colonies in very dynamic and extremely shallow water conditions.

Opis:

The growth of carbonate buildups in the northern, stable shelf of the Tethyan Ocean was the principal factor in the development of diversified sea-bottom relief in the Late Jurassic basin. Reconstruction of this relief has been a matter of numerous controversies. This paper provides an analysis of published data on elevation differences on sea bottom along the SW margin of the Holy Cross Mts. and in the Cracow-Wielun Upland. Moreover, methods of reconstruction of synsedimentary relief are presented. In the Late Oxfordian the elevations on basin floor in the Czestochowa area (Cracow-Wielun Upland) were about 100 meters at most, and were presumably even lower. The largest (over 200 meters) elevation differences of sea-bottom relief existing in the Czestochowa area at the Oxfordian/Kimmeridgian have been postulated when the recently observed differences in thickness between the deposits of carbonate buildup and of equivalent basinal facies were identified as a relief. In fact, different thickness is, in considerable part, an effect of differential compaction.
Wzrost budowli węglanowych na północnym, stabilnym szelfie Tetydy był główną przyczyną powstania urozmaiconego reliefu dna w basenie późnojurajskim. Rekonstrukcja tego reliefu jest przedmiotem licznych kontrowersji. Praca analizuje dane literaturowe o wielkości deniwelacji dna z rejonu SW-obrzeżenia Gór Świętokrzyskich i Wyżyny Krakowsko-Wieluńskiej oraz omawia metodykę rekonstrukcji reliefu synsedymentacyjnego. Deniwelacje dna basenu u schyłku oksfordu w rejonie Częstochowy wynosiły co najwyżej około 100 m a przypuszczalnie były jeszcze mniejsze. Postulowane wcześniej, ponad dwustumetrowe deniwelacje w basenie w rejonie Częstochowy na przełomie oksfordu i kimerydu były oparte na utożsamianiu z deniwelacjami dna aktualnej różnicy miąższości między utworami budowli węglanowej a ekwiwalentnymi jej utworami facji basenowej. Różnica ta jest w znacznej części wynikiem zróżnicowanej podatności osadów na kompakcję.

Laboratory results of total porosity and physical permeability were the basis to calculate Flow Zone Indicator. GR log and porosity log PHI were used for facies identification. Calculations and loggings were performed in the Miocene sandy-shaly sediments in two wells in the Eastern Part of Polish Carpathian Foredeep. FZI increase with the total porosity from the comprehensive interpretation of logs in the regressive set of parasequences was observed. This increase was the result of better reservoir and hydraulic abilities of these parasequences in comparison to transgressive ones. Combining information of laboratory origin with well logging results on the basis of facies and FZI correlation worked also as a kind of data scaling.

Opis:

The Jurassic of the Alpine-Mediterranean Tethys was characterized by the formation of several interconnected basins, which underwent gradual deepening and oceanization. Sedimentation in each basin was influenced by a specific set of interrelated factors, such as tectonic activity, seawater circulation, climate, chemistry and trophic state of seawater as well as evolutionary changes of the marine biota. This paper deals with the Fatricum Domain (Central Carpathians, Poland and Slovakia), which in the Jurassic was a pull-apart basin on a thinned continental crust. The sedimentation history of this domain during the Bajocian-Tithonian and its governing factors have been revealed. Facies analysis of the Bajocian-Oxfordian deposits evidences considerable relief of the basin-floor topography. Deposits in the Western Tatra Mts represent sedimentation on a submarine intrabasinal high, whereas the coeval deposits of the eastern part of the Tatra Mts accumulated in a deeper basin. The basin succession began with Bajocian bioturbated “spotted” limestones and siliciclastic mudstones (Fleckenmergel facies). These were succeeded by uppermost Bajocian - middle Bathonian grey nodular limestones, affected by synsedimentary gravitational bulk creep. The coeval deposits of the intrabasinal high are represented by well-washed Bositra-crinoidal limestones with condensed horizons. Uniform radiolarite sedimentation commenced in the late Bathonian and persisted until the early late Kimmeridgian. The basal ribbon radiolarites (upper Bathonian - lower Oxfordian), which consist of alternating chert beds and shale partings, are a record of seawater eutrophication, a related crisis in carbonate production and the rise of the CCD, which collectively resulted in biosiliceous sedimentation. The overlying calcareous radiolarites (middle Oxfordian - lowermost upper Kimmeridgian) marked a gradual return to carbonate sedimentation. The return of conditions that were favourable for carbonate sedimentation took place in the late Kimmeridgian, when the red nodular limestones were deposited. They are partly replaced by basinal platy limestones (uppermost Kimmeridgian - Tithonian) in the Western Tatra Mts. This lateral variation in facies reflects a change in the sedimentary conditions governed by a bathymetric reversal of the seafloor configuration, attributed to a further stage in the pull-apart transcurrent tectonics of the Fatricum Domain.

Opis:

A comparative sedimentological analysis of the Upper Jurassic–Lower Cretaceous deposits carried out on drill-cores from the southern part of the Carpathian Foredeep allowed us to distinguish thirteen main microfacies types. The results of microfacies analyses and stratigraphical data made it possible to propose a lithological subdivision of the southern part of the Upper Jurassic and Lower Cretaceous sediments of the Carpathian Foredeep basement between Kraków and Rzeszów. In the analysed wells, three main sedimentary complexes were distinguished, embracing the following intervals: (i) Callovian–Oxfordian, (ii) Kimmeridgian and (iii) Tithonian– Berriasian–Valanginian. The Oxfordian, Kimmeridgian and Tithonian deposits represent the outer – mid homoclinal ramp facies, whereas the Berriasian and Valanginian deposits belong to the inner homoclinal ramp facies. Complexes of microbial-sponge reefs, with a distinct relief, could be recognised in the Upper Oxfordian sediments only. The development of these buildups took place in a basin typified by diversified morphology, determined by the block-type structure of the Palaeozoic basement and synsedimentary tectonics, which brought about substantial variability in thickness of the Oxfordian sediments. At the end of the Oxfordian, large complexes of the reef facies were replaced mainly by microbial-sponge and microbial-coral biostromes developed during the Kimmeridgian and Tithonian. In the principal part of the studied area (except the western part of the described fragment of the Carpathian Foredeep; Kraków area) during the Kimmeridgian, Tithonian, Berriasian and Valanginian, sedimentation occurred in a basin typified by homogeneous morphology, which resulted in a wide extent and comparable thicknesses of the distinguished facies types. In the studied sections, indications of partial or complete dolomitization were observed in a large part of the sediments. Four generations of dolomite document a complex diagenetic history with multiple episodes of dolomite formation: from early diagenetic environment to late burial conditions.

Opis:

In the epicontinental Jurassic of Poland, scleractinian corals appeared in the Bathonian, but only in the Middle Oxfordian-Lower Kimmeridgian became a significant element of the shallow-water fauna. Over the whole area, Upper Jurassic coral facies are situated above the Oxfordian sponge megafacies. Middle Oxfordian Jurassic corals are the best known from the NE margin of the Holy Cross Mts and represented chiefly by lamellate colonies. The Upper Oxfordian and Kimmeridgian coral facies extends from the Pomerania, through central Poland to the fore-Carpathian region. Taxonomical and morphotypical coral diversifications of the Upper Oxfordian and Kimmeridian were higher than that of the Middle Oxfordian. In the Tethyan region, corals are known from the exotic pebbles of the Stramberk-type Tithonian limestones in the Carpathian Flysh and Pieniny Klippen Belt. The arguments against the interpretation of epicontinental coral accumulations as reefs, are as follows: abundance of lamellate corals and epithecate phaceloid taxa (the latter incapable to repair skeletal damages), high taxonomical diversification and frequency of corals with menianes representing presumable adaptations to filtering mode of nutrition, comparable rate of growth of coral constructions and of accumulation of surrounding sediment, association of corals characterized above with soft bottom and turbid water.

Opis:

The present article focuses predominantly on sandy deposits that occur within the Middle Miocene lignite seam at the Tomisławice opencast mine, owned by the Konin Lignite Mine. As a result of mining activity, these siliciclastics were available for direct observation in 2015–2016. They are situated between two lignite benches over a distance of ~500 m in the lower part and ~200 m in the higher part of the exploitation levels. The maximum thickness of these sandy sediments, of a lenticular structure in a S–N cross section, is up to 1.8 m. With the exception of a thin lignite intercalation, these siliciclastics comprise mainly by fine-grained and well-sorted sands, and only their basal and top layers are enriched with silt particles and organic matter. Based on a detailed analysis of the sediments studied (i.e., their architecture and textural-structural features), I present a discussion of their genesis and then propose a model of their formation. These siliciclastics most likely formed during at least two flood events in the overbank area of a Middle Miocene meandering or anastomosing river. Following breaching of the natural river levee, the sandy particles (derived mainly from the main river channel and levees) were deposited on the mire (backswamp) surface in the form of crevasse splays. After each flooding event, vegetation developed on the top of these siliciclastics; hence, two crevasse-splay bodies (here referred to as the older and younger) came into existence. As a result, the first Mid-Polish lignite seam at the Tomisławice opencast mine is currently divided in two by relatively thick siliciclastics, which prevents a significant portion of this seam from being used for industrial purposes.

Opis:

Aim of the study was to investigate the detailed stratigraphic architecture of the alluvial Volkovce Formation, which was deposited in the northern Danube Basin during the interval between 10 and 6 Ma. Two type locality exposures were subject to facies analysis and interpretation of depositional processes and >500 boreholes served for correlation of spatial variability in the character of the formation. The study was focused on the northern Blatné and western Rišňovce depressions, which are partly separated by the Považský Inovec Mountains horst. It was revealed, that a mostly gravelly fluvial distributary system of the Piešťany Member was deposited in the northern Blatné depression, partly confined by the exposed horst and by incised palaeotopography. The sequence is composed of amalgamated braided river channel bodies with no overbank strata, in response to high sediment supply and low accommodation. The palaeo-stream then crossed the horst in its southern part towards the Rišňovce depression, where there was four times more accommodation. The submerged horst acted as a boundary, where the depositional processes changed to a meandering river and significant overbank deposits started to be preserved. Only small streams were present in the northern Rišňovce depression, which led to very low sediment supply compared to the high accommodation there. The depositional system was affected mainly by the incised palaeotopography, by the location of sediment input together with spatial differences in accommodation rate caused by the activity of the Ripňany Fault on the southeastern side of the Považský Inovec Mts.

Opis:

Late Cretaceous inversion processes and their relation to salt movements in the Pomeranian sector of the Mid-Polish Trough are described, based on deep boreholes. Two tectonic zones, inverted in the Late Cretaceous, located in the Mid-Polish Trough, were selected for study: the Koszalin-Chojnice Zone situated NE of the present-day Mid-Polish Swell in the Pomeranian Trough, within an area of non-salt anticlines, and the Drawno-Człopa-Szamotuły Zone located in the Szczecin Trough, SW of the Mid-Polish Swell, in an area of strong salt tectonics. The stratigraphic gaps present indicate that the first pulse of Late Cretaceous inversion might have occurred in the Coniacian-early Santonian in this area. Another pulse can be dated at late Campanian-early Maastrichtian. Intra-Cretaceous stratigraphic gaps reached their maximum areal extent in the Coniacian (Inoceramus involutus Zone) and Upper Campanian (Koszalin-Chojnice Zone). Over large areas, Santonian (mostly upper Santonian) deposits rest upon Turonian (including Inoceramus schloenbachi Zone), and locally on older rocks. The lithofacies maps show that thickness and lithofacies distribution in the Cenomanian was independent of the strike of the Koszalin-Chojnice Zone. Such a dependence began and was accentuated in the Coniacian. Santonian and Campanian clastic deposits, extending along the SW boundary of the Mid-Polish Swell and absent in the SW part of the Pomeranian Trough, suggest local tectonic inversion within the central part of the Mid-Polish Trough.

Opis:

The present account summarizes the results of lithological and facies analysis of representative sections of the Godula Formation, in order to contribute to the understanding of the lithofacies structure of this formation, the processes involved in its development and the character of the depositional environment. The sedimentology of different parts of the Godula Formation was investigated in six representative sections in the western and central parts of the Moravskoslezské Beskydy Mts. The Godula Formation is made up mainly of Upper Cretaceous siliciclastic turbidites and was formed during the most significant depositional phase of the filling of the deep-sea Silesian Basin. On the basis of sedimentological research, five facies classes (including four subclasses) were defined: 1) conglomeratic sandstones, 2) sandstones, 3) sandstones with mudstones, 4) mudstones with sandstones and siltstones, and 5) mudstones with siltstones. The methodology of facies analysis allowed the identification of several facies association, corresponding to the medial and distal parts of a turbidite fan and associated siliciclastic apron. The facies of depositional lobes, lobe transitions and the apron are described. The sandstone and mudstone facies (F3) occurs mostly in the depositional lobes. The sandstone facies (F2) and mudstone with sandstone and siltstone facies (F4) are present only to a lesser degree. The facies of the lobe transitions include lithologic associations of the lobe fringe and channel levee environments. They comprise mainly the mudstones with sandstones and siltstones (F4) and the mudstone with siltstone facies (F5). In the apron deposits, the sandstone facies (F2) and the conglomeratic sandstone facies (F1) predominate. Palaeocurrent analysis from measurements made in selected profiles showed that in the Moravskoslezské Beskydy Mts., the dominant direction of sediment transport was from SW to NE. After applying correction of the known counterclockwise rotation of the nappes of the Outer Carpathians, this corresponds to a longitudinal direction along the original axis of the basin.

Opis:

Non-tectonic, soft-sediment deformation structures occur in mid-Miocene crevasse-splay deposits exposed in the Tomisławice lignite opencast mine in central Poland. The crevasse-splay cross-stratified siliciclastic deposits are underlain by continuously folded and relatively thick lignite beds, and overlain by a thin undisturbed layer of lignite. Only the middle part of the crevasse-splay succession is deformed plastically in the form of folds, while the lower and uppermost beds are undeformed. Most of the intraformational deformation structures are recumbent folds, while only a few can be classified as upright folds in the initial stage of their evolution. The origin of these folds is associated here with a penecontemporaneous slumping process caused by liquefaction of sandy-muddy sediments. The slumping was triggered by an increase in the inclination of heterolithic layers caused by the compactional subsidence of an organic-rich substrate - peat. This type of subsidence occurred following a sudden siliciclastic load on top of the underlying and poorly-compacted peat/lignite seam. The initiation and development of the slump folds can be explained by differentiated loading, compaction and liquefaction processes, and the introduction of a tectonic agent is unnecessary.

Opis:

In the Triassic-Jurassic boundary profiles of the Upper Silesian region, there are locally developed coarse clastic deposits, commonly known as the Połomia Gravels, Połomia Beds or “Połomia Formation’’ (informal name). Due to the lack of reliable stratigraphic tools, the chronostratigraphic position of these deposits remains one of the most controversial aspects of the Triassic-Jurassic lithostratigraphy in the region. Sparse biostratigraphic data from the overlying and underlying deposits indicate a wide range of ages, from the Late Triassic to Early Jurassic. This paper presents the results of sedimentological, petrographical and palynological analyses of the coarse-grained deposits from the Kamienica Śląska gravel pit, which is currently one of the biggest facilities of this type in Upper Silesia. The outcrop section, with a total thickness of up to 20 m, is dominated by friable, light grey to beige and locally dark grey, large-scale planar to trough cross-stratified conglomerates and coarse-grained sandstones with subordinate thin interbeds of grey and reddish brown mudstones. Three facies associations have been distinguished, representing a main channel belt, secondary channels and floodplains subenvironments. Facies analysis points to a braided river tract with localised floodplain sediments. The grain composition of the Kamienica Śląska gravel/conglomerate is less diversified than that of the polymictic typical Połomia Beds of the Myszków area and resembles oligomictic conglomerates known from the Grabowa Formation of the Norian age and/or conglomerates of the Gorzów Beds of Rhaetian age, which also occur on the studied region. Palynological analysis of mudstone interbeds within the conglomeratic deposits shows the presence of miospores guiding and characteristic for subzone c of the Corollina meyeriana zone of the late Norian-early Rhaetian age. The appearance of the coarse-grained deposits in late Norian could be associated with the development of a long-reach braided fluvial tract, draining the S and SE part of the Sudetian-Malopolska-Lublin land (S-M-L land) in response to the tectonic rearrangement in the source area and gradual climatic change from semi-arid to humid in the Rhaetian.

Opis:

The new boreholes drilled between 2009 and 2012 enabled a detailed exploration of the profile of the Kraków sandstone series in the Dąb area between the “Sobieski” and “Janina” mining plants, USCB (Upper Silesian Coal Basin). The core from the No. 111. bituminous coal seam was selected for further analysis. 30 intervals corresponding to the defined lithotypes were separated in the seam with a thickness of 116.8 cm. The thickness of lithotypes ranges from 10 mm to 89 mm. A microprofile of the examined seam was made using the modified method of determining microlithotypes. A quantitative determination of the maceral composition was performed for each interval corresponding to the separated lithotypes. This allowed petrographic and facies characteristics of the seam to be determined. Its lower part is dominated by lithotypes with a large share of bright coal – vitrain coal. This section of the profile was formed under conditions of a strongly flooded wet forest swamp. In the upper section of the seam, a higher macroscopic share of dull coal – durain was observed. The microscopic analysis has shown that the conditions dominant during the formation of this section were typical for swamp forest peats. New technologies also require expanding knowledge about the structure of coal seams. This is only possible with a detailed profiling of the coal seam on a macro scale combined with micro-profiling and a detailed petrographic description of the isolated lithotypes. This methodology is also useful in the facies analysis of bituminous coal seams.
Nowe odwierty w latach 2009–2012 rozpoznały szczegółowo profil utworów krakowskiej serii piaskowcowej w rejonie miejscowość Dąb pomiędzy granicami zakładów górniczych Sobieski i Janina, GZW. Z nawierconych pokładów węgla do dalszych badań pobrano rdzeń pokładu węgla Kamiennego 111. W pokładzie o miąższości 116,8 cm wydzielono 30 interwałów odpowiadających zdefiniowanym litotypom. Miąższość litotypów waha się w przedziale od 10 do 89 mm. Za pomocą zmodyfikowanej metody wydzielania mikrolitotypów wykonano mikroprofil badanego pokładu pokładu. Dla każdego interwału odpowiadającego wydzielonym litotypom wykonano oznaczenie ilościowe składu macerałowego. Pozwoliło to na charakterystykę petrograficzną, jak i facjalną pokładu. Dolna jego część zdominowana jest przez litotypy mające duży udział węgla błyszczącego – witrynu. Ten odcinek profilu tworzył się w warunkach torfowiska silnie podtopionego typu Wet Foret Swamp. W odcinku górnym pokładu zaobserwowano makroskopowo większy udział węgla matowego – durynu. Badania mikroskopowe wskazują, że podczas tworzenia się tego odcinka dominowały warunki wskazujące na torfowisko typu Swamp Forest. Nowe technologie przetwarzania węgla wymagają również poszerzenia wiedzy na temat budowy pokładów węgla. Jest to możliwe tylko dzięki szczegółowemu profilowaniu pokładu węgla w skali makro w połączeniu z mikroprofilowaniem i szczegółowym petrograficznym opisem wydzielonych litotypów.

Opis:

The Neogene sedimentary succession of the Orava-Nowy Targ Basin directly overlies the Central Carpathian Paleogene Basin deposits, the Magura Unit, and the Pieniny Klippen Belt. It provides an excellent geological record that postdates the main Mesoalpine structural and geomorphological processes in the Western Carpathians. Sedimentological, petrographical and geochronological investigations have allowed forthe re-examination of pyroclastic material, zircon dating, and a discussion on the relation of the Orava-Nowy Targ Basin to the exhumation of the Tatra Massif. The Bystry Stream succession is composed of NNW-inclined freshwater siltstones, sandstones and conglomerates. A few small, sometimes discontinuous, light grey intercalations of pyroclastic deposits and a single 1-2 m thick tuffite layer occur in the upper part of the succession. The tuffite contains an admixture of organic matter and siliciclastic grains (e.g., mica), suggesting that the volcanic ash fall was accompanied by normal deposition from weak currents. Sedimentation of deposits of the Bystry Stream succession took place in terrestrial settings, predominantly on floodplains and in rivers, in the vicinity of a hilly area supplying the basin with eroded material. The age of the tuffite layer from the Bystry Stream succession was determined at 11.87 +0.12/-0.24 Ma. The source of volcanogenic material in the tuffite was probably volcanic activity in the Inner Carpathians-Pannonian region, where effusive and volcanoclastic sillca-rich rocks were being produced by extrusive and explosive activity ~12 Ma. Obtained result connects the development of the Orava-Nowy Targ Basin at ~12 Ma with the late stage of the main episode of the Tatra Massif exhumation between ~22-10 Ma.

Opis:

This article reports on the first detailed study of the Skole Nappe’s Ropianka Formation in the Słonne outcrop section along river San. Lithological and micropalaeontological similarities indicate that the sedimentary succession correlates with the formation’s Wiar Member of Campanian–late Maastrichtian age. The sedimentary succession, more than 140 m thick, is interpreted as a deep-marine complex of turbiditic depositional lobes and the study reveals its sedimentary anatomy. Six component facies of sediment gravity-flow deposits and their stratigraphic grouping into four facies associations are recognized, with these latter considered to represent deposits of the lobe axial zone, lateral flank zone and featheredge fringe zone, as well as an interlobe outer-fringe zone. Semi-quantitative characterization and comparison of facies associations gives insight into the succession’s sedimentary heterogeneity. Six depositional lobes superimposed upon one another are recognized in the stratigraphic succession, and their pattern of vertical stacking is interpreted in terms of dynamic stratigraphy on the basis of the upward succession of facies associations. The stratigraphic arrangement of facies associations is attributed to autogenic morphodynamic changes within the evolving depositional system, although it cannot be precluded that also eustatic and local tectonic forcing came into play. The case study sheds more light on the sedimentary environment, sediment sourcing system and spatial depositional pattern in the Late Cretaceous Skole Basin, where the aggrading seafloor apparently oscillated around the lysocline depth that could be mid-bathyal at that time.

Opis:

Celem niniejszej pracy jest zaprezentowanie szczegółowej dokumentacji facji warstw krośnieńskich południowego skrzydła fałdu Gorlic, odsłaniających się w korycie rzeki Sękówka, na odcinku Gorlice–Sękowa. Na podstawie prac terenowych wykonano szczegółowy profil litologiczny uwzględniający cechy sedymentologiczne, o łącznej rzeczywistej miąższości 1415 m. W obrębie warstw krośnieńskich wydzielono i opisano 11 facji osadowych (I–XI), dla których na tym etapie badań nie interpretowane jest środowisko depozycji. Wydzielono i opisano 3 rodzaje osadów heterolitowych. Rozpoznano i udokumentowano również 15 struktur sedymentacyjnych, które zostaną wykorzystane do dalszej interpretacji warstw krośnieńskich w zakresie ich genezy. Kolejnym elementem zrealizowanym w pracy jest korelacja terenowego profilu litologicznego z zapisem i interpretacją profilowań geofizyki wiertniczej (wystandaryzowanych do jednostek fizycznych psAPI, petrofizyczny trójskładnikowy model matrycy) z otworów Gorlice-12 i Gorlice-13, przewiercających bezpośrednio badany interwał litostratygraficzny. Wszystkie trzy profile zostały zestawione i odniesione do granicy stropu warstw menilitowych (poziom wyrównania), która jest bardzo dobrze widoczna, zarówno w terenie, jak i w zapisie krzywych geofizyki otworowej. Przyjęta metodyka pozwoliła na wyznaczenie 5 charakterystycznych granic: G1, G2, G3, G4, G5. Wyznaczone one zostały w spągu piaskowców masywnych przypisanych facji VIII (granice G1, G2, G4, G5) i piaskowców słabo zwięzłych – facja IX (granica G3). Dodatkowo ustalonych zostało 5 linii pomocniczych (P1, P2, P3, P4, P5) na podstawie podobieństwa zapisu profilowania gamma. Wykonany profil terenowy został porównany z jego archiwalnym opisem, czego efektem jest wykazanie różnic w rzeczywistej miąższości, oraz stopniem zmienności litologicznej. Przeprowadzone badania oraz zastosowana metodyka mogą stanowić podstawę do weryfikacji dotychczasowego stanu wiedzy na temat warstw krośnieńskich na szerszym obszarze badań, gdzie występują otwory wiertnicze, jak i profile terenowe. Mogą być one wykorzystywane do regionalnych interpretacji zmienności facjalnej i środowisk depozycji.
The main objective of this paper is to present documentation of the Krosno Beds facies in the southern limb of the Gorlice Fold, exposed in the Sękówka river bed, on the Gorlice–Sękowa section. On the basis of field work, a detailed lithological profile was compiled, taking into account sedimentary structures. The total true thickness of the profile is 1415 m. Eleven sedimentary facies (I-XI) are described, for which the depositional environment has not been interpreted at this stage of the research. Three types of heterolithic sediments were described. Fifteen sedimentary structures have been identified and documented, which will be used for future interpretation of the Krosno Beds sedimentary environment. Another element conducted in the study is the correlation of the lithological field profile with the well logs interpretation (standardized to psAPI physical units, evaluation of the petrophysical model) from the Gorlice-12 and Gorlice-13 boreholes directly drilling through the studied lithostratigraphic interval. All three profiles have been correlated with reference to the datum defined by the upper boundary of the Menilite Beds which is clearly identifiable both in the field and in the well logs. The adopted methodology made it possible to define 5 correlation boundaries (G1, G2, G3, G4, G5), based on the massive sandstones – facies VIII (boundaries G1, G2, G4, G5) and low-compact sandstones – facies IX (boundary G3). In addition, 5 auxiliary lines have been marked (P1, P2, P3, P4, P5) based on the similarities of the gamma well logs. The field profile was compared with its archival description, the results of which shows differences in the true thickness and the degree of lithological variability. The conducted research and the applied methodology may provide the basis for verifying the current state of knowledge on the Krosno Beds in a regional border area, where there are boreholes and field profile. They can be used for regional interpretations of facies variability and deposition environments.

Workflow of 3D static reservoir modelling, with the emphasis on the different types of data integration is discussed in the paper. The example of two-stage integration of geophysical (seismic and well log), petrophysical, sedimentological and reservoir engineering data within a framework of 3D static reservoir models is given. The main goal of the first stage of data integration is to obtain consistent well profiles of reservoir parameters such as: porosity, permeability, facies, water saturation. For that purpose the example of use of the following data types were presented: well logs, lab data, sedimentological interpretation, well tests and mud logging results. The second stage includes construction of structural model, defining the geometry of analyzed geological object, facies/lithological modelling; calibration of facial and petrophysical well profiles with 3D seismic, usually represented by results of seismic inversion, seismic attributes and meta-attributes and finally, the calculation of the spatial distribution of analyzed reservoir properties.

Opis:

This paper examines the depositional environment and diagenetic aspects of the exposed Patcham and Chari formation within the Habo Dome. The Patcham Formation is represented by the Black Limestone Member. The Chari Formation is represented by two distinct sedimentary successions: (i) shale and carbonates, and (ii) coarse clastics. The paper describes eleven lithofacies from these successions. The depositional framework constituents of these facies have been greatly modified by diagenetic evolution through time. Two main depositional environments, i.e. foreshore intertidal and shoreface (subtidal), have dominated during their deposition. The diagenetic signatures observed within these sediments suggest early or syndepositional changes in marine phreatic and burial environments. Two phases of early mechanical compaction have largely governed porosity evolution within the limestone facies. Micritization of the allochems was caused by endolithic algae prevalent within the restricted lagoon environments with stagnant marine phreatic zone conditions. Random dissolution of microcrystalline grains has created vugs with patchy distribution reflecting neomorphism within the meteoric vadose zone. The types of cements within the sandstone facies include silica, calcite, and its replacement by Fe-calcite cement. The sandstones were deposited in a relatively low energy environment below storm wave base. The depositional conditions have controlled the early diagenesis of the sandstones which in turn have influenced their burial diagenesis.

Opis:

The study uses quantitative methods to analyse the latest Bartonian to Early Rupelian sedimentary succession at the SE outskirts of the Polish Lowland Paleogene Basin, in the back-bulge zone of the Carpathian orogenorebulge. The vertical lithotype proportion diagrams from a large number of well logs are compiled to reveal the area’s sequence stratigraphy. Six sequences are recognized and correlated with 3rd-order eustatic sea level cycles. The basal sequence of type 1 is overlain by three sequences of type 2 and followed by a fifth sequence of type 1, whose depositional forced-regressive and lowstand systems tracts brought the main volume of quartz-glauconite sand to the study area. The study focuses further on the deposits of this fifth sequence, exposed and surveyed with GPR in the Nowodwór-Piaski sand pit. Their sedimentary facies analysis reveals the local spatial pattern of a wave-dominated and tidally-influenced sedimentation, supporting the earlier notions of a southern palaeoshoreline and a tectonically-controlled sedimentation.The analysis, aided by multidimensional GPR survey, indicates syndepositional development of a tectonic graben filled laterally by fault scarp-attached large sand bars and an axial action of tidal ebb currents. The bars were formed of shore-derived sand swept by littoral waves from the graben footwall areas. As the graben’s tectonic activity ceased, it became buried by the lowstand regressive sands overlain by gravelly foreshore deposits, most of which were later removed by the Pleistocene glacial erosion. A 3D model of the deposits in the Nowodwór-Piaski area is constructed on the basis of outcrop and GPR data with the use of multiple-point statistical methodology to depict the internal architecture, heterogeneity and spatial relationships of main sedimentary facies. The model can serve as a guide for the future exploration and exploitation of the quartz-glauconite sands in the area and as instructive example of how a petroleum reservoir model of a complex sedimentary succession can be constructed with the use of modern statistical methods.

Opis:

The distribution of Permian alluvial fan lithofacies in a quarry at Zygmuntówka near Chęciny, Holy Cross Mts., in southern Poland was investigated using ground penetrating radar (GPR) in order to create a training image for multiple point statistics (MPS) reconstructions of alluvial fan sedimentary facies. Five pseudo-3D GPR datasets were collected, processed and uploaded for interpretation into SKUA-GOCAD 3D geological modelling software. Three radar facies were distinguished based on the 3D geometrical pattern of radar reflections and linked to lithofacies described from the quarry by Zbroja et al. (1998). A statistical summary showed that ~50% of the lithofacies resulted from gravity flows (mostly non-cohesive), while the remaining proportion was deposited by unconfined and confined flash floods. Fluvial sedimentary facies left by waning of catastrophic floods or reworking during fair weather, alihough not prevalent, could not be distinguished from confined flood deposits based only on GPR data. The GPR datasets together with information from field observations were used to carry out MPS simulations and estimate the most probable 3D model of lithofacies at the quarry scale. This model will in turn serve as a training image for MPS reconstructions of alluvial-fan facies of Rotliegend conglomerates in the multi-scale geological model of the Gorzów Block (western Poland).

W profilach badanych odwiertów opróbowano ławice węgla występujące w 11 interwałach w otworze Z-1/11 i 14 odcinkach w otworze Z-2/12 (rys. 2). Wykonane badania petrograficzne węgla pozwoliły na oznaczenie stopnia uwęglenia na podstawie pomiarów refleksyjności. Pomierzona refleksyjność średnia (Ror) w otworze Z-1/11 wynosi 0,81%, a w otworze Z-2/12 – 0,84% i wskazuje na zbliżony stopień uwęglenia w obydwu badanych odwiertach, który odpowiada zgodnie z polską normą PN-82/G-97002 węglowi gazowemu o wyróżniku 33. Zgodnie z International Classification of In-Seam Coal na podstawie składu petrograficznego węgiel w obu badanych odwiertach określono jako humusowy. Ze względu na stopień uwęglenia, mierzony wskaźnikiem refleksyjności (Ror) węgiel określono jako medium-rank C (orto-bituminous). Pod względem zawartości popiołu węgiel z poszczególnych pokładów lokuje się w bardzo szerokim zakresie zmienności od high grade coal poprzez medium-low-very low grade coal aż do carbonoceus rock. [...]
The Z-1/11 and Z-2/12 drillings are located north of the closed „Morcinek” coal mine – situated near Cieszyn, close to the Polish-Czech border (Fig. 1). The coal seams in the area are found in Carboniferous coal-bearing formations within the north-western part of the main basin, which is the central part of the Upper Silesian Coal Basin. The profiles of examined drillings included the samples of coal occurring in 11 intervals in the Z-1/11 drilling and 14 sections in the Z-2/12 drilling (Fig. 2). Petrographic studies of coal seams from the Z-1/11 and Z-2/12 drillings allowed to identify the rank of coal on the basis of reflectance measurements. Random reflectance (Ror) of collotelinite in the Z-1/11 drilling is 0.81%, while in the Z-2/12 drilling it is 0.84%. Measured values indicate similar coal rank in both drillings, which corresponds to – according to Polish standard PN-82/G-97002 – gas coal type 33. According to the International Classification of In-Seam Coal, and therefore on the basis of petrographic composition, the coal from both boreholes has been identified as humic coal. On the basis of the rank of coal, measured using the random reflectance (Ror), the coal has been identified as medium-rank C (ortho- bituminous). In terms of ash content, coal from the individual seams has a very high variability, ranging from high grade coal through medium-low-very low grade coal up to carbonoceus rock. [...]

Opis:

Thick deep-water sandstone successions are known from many localities in the Outer Western Carpathians. The present study is focused on comparison of deposits of the Piwniczna (PwSM) and Poprad (PpSM) Sandstone members belonging to the Magura Formation of the Magura Unit, outcropping in the eastern Slovakia and Poland border area. At the general level, a close similarity of the sandstone successions was confirmed by this study. However, in more detail, facies analysis shows differences in the thickness of the sandstone successions, in grain size and in the character of intervals between the thick sandstones. Thin-section study, though, showed almost the same modal composition in the sandstones analysed. The sandstone successions studied are interpreted as sandy debrites, the PwSM showing transitional facies to turbidites. These deposits rep resent channelized depositional lobes in the proximal part of a submarine fan with the PpSM closer to the source. The sediment source area was common to both lithostratigraphic units, and was most likely the South-Magura Ridge.

Opis:

This study focuses on the single- and multi-storey fluvial palaeochannel lithosomes encased in mud- rich floodplain deposits in the alluvial succession of the late Neogene Wielkopolska Member of the Poznań For- mation, central Poland, well-exposed in the lignite mining pits of the region. The fluvial lithosomes include both sand-filled and mud-filled channel varieties. The channel-fill facies are not diagnostic for any particular type of fluvial system, as the fine- to very fine-grained sandy deposits are massive to trough cross-stratified and also the muddy deposits are massive to weakly flat-laminated. The scarcity of lateral accretion bedding precludes the possibility of meandering rivers, whereas the low width/thickness ratios of the palaeochannels preclude braided rivers. The width/thickness ratio is in the range of 4.5–14 (averaging 7.5) for sand-filled channels and in the range of 6–10 (averaging 9) for mud-filled ones, which indicates narrow ribbons in general classification of fluvial channel belts. The origin of the alluvial succession is attributed to a W-/NW-directed anastomosing river system characterized by laterally inactive cut-and-fill channels with cohesive and vegetated banks. The sand-filled chan- nels conveyed water and sediment discharges on a perennial basis, whereas the mud-filled conduits are thought to have been the cut-and-abandoned branches of the system, filled by overbank flooding from adjacent active channels. Minor lateral migration of channels occurred probably during periods of minimum subsidence rate, when the fluvial system was forced to develop lateral accommodation for its discharges.

Opis:

The paper summarises the effects of recent studies carried out by a team from the Department of Historical and Regional Geology of the Faculty of Geology, University of Warsaw on the upper Silurian of Podolia (western part of Ukraine). The sedimentary history of the Silurian succession of Podolia is characterised by its cyclic pattern, with shallowing-upward cyclothems. In the traditional interpretation, the occurrence of stromatoporoid beds within each cyclothem marks the deepest (or most open-marine) sedimentary environment within the cycle. According to the results of recent studies, their occurrence is connected rather with a relatively shallow-water environment and with high energy phenomena. A substantial reinterpretation of the main sedimentary processes governing the deposition and facies distribution on the shelf is presented. Particularly, there are recognised and described high-energy sedimentary events repeatedly punctuating the generally calm sedimentation that prevailed in the lagoonal settings, some of which are interpreted as tsunami induced. Further perspectives for studies on the Silurian successions of Podolia are also discussed. The main problem is the precise correlation of particular sections that are scattered over vast distances and developed in similar facies associations.

Opis:

With approximately 100 species, the invertebrate macrofauna of the Neuburg Kieselerde Member of the Wellheim Formation (Bavaria, southern Germany) is probably the most diverse fossil assemblage of the Danubian Cretaceous Group. Occurring as erosional relicts in post-depositional karst depressions, both the Cretaceous sediments and fossils have been silicified during diagenesis. The Neuburg Kieselerde Member, safely dated as Early Cenomanian to Early Turonian based on inoceramid bivalve biostratigraphy and sequence stratigraphy, preserves a predominantly soft-bottom community, which, however, is biased due to near-complete early diagenetic loss of aragonitic shells. The community is dominated by epifaunal and semi-infaunal bivalves as well as sponges that settled on various (bio-) clasts, and may widely be split into an early bivalve-echinoid assemblage and a succeeding sponge-brachiopod assemblage. In addition to these groups we document ichnofauna, polychaete tubes, nautilids and bryozoans. The fauna provides evidence of a shallow to moderately deep, calm, fully marine environment, which is interpreted as a largescale embayment herein. The fauna of the Neuburg Kieselerde Member is regarded as an important archive of lower Upper Cretaceous sea-life in the surroundings of the Mid-European Island.

Opis:

The loess subsoil constitutes over 50% of the Lublin area and determines the geotechnical conditions of the western side of the River Bystrzyca. The paper discusses the geological structure of this part of Lublin and presents an analysis of the results of field research carried out by the author. The research methodology and the method of deriving parameters for the loess subsoil are also proposed. The Lublin loesses were divided into three main facies groups: aeolian (typical loess), aeolian-diluvial and aeolian-alluvial. The basis for the division and parametric characteristics of individual facies were mainly in-situ tests: CPT/CPTU static soundings, DMT/SDMT flat dilatometer tests and PMT Menard pressuremeter tests. The collected data allowed characterizing each of the facies groups and developing a synthetic geological cross-section representing the geological structure of the western part of Lublin. The number of analysed tests allowed stating that the data from CPT/CPTU static soundings are representative for Lublin. Data from DMT/SDMT tests can be considered representative, but further research is needed to refine them and, for example, to separate them by facies. Data from pressuremeter tests should be treated as preliminary. The analyses show that the most common facies in Lublin is silty aeolian one called typical loess, which, according to the author, constitutes approximately 75-80%, and their parameters are of key importance for the design of buildings. The remaining facies groups are about 8-15% for aeolian-diluvial loess and 8-10% for aeolian alluvial loess. Typical loesses are macroscopically homogeneous, but their varying stiffness is reflected in in-situ tests. The basic research method for loess subsoil should be CPT/CPTU static soundings, while the most representative parameter for geotechnical layers is the cone resistance qc. Details of the geological structure and parameters should be performed with DMT, SDMT and PMT tests, as well as laboratory tests, the necessary scope of which can be determined after the development of the subsoil model from the results of CPT tests.

Opis:

A detailed sedimentological study of the Lower-Middle Muschelkalk (Middle Triassic) carbonate succession exposed at the “Stare Gliny” quarry near Olkusz (Kraków-Silesia region, southern Poland) revealed numerous vertebrate remains within its lowermost sedimentary unit. This 7-m-thick package onlaps a gently-inclined surface of a paleoisland made of the Devonian (Givetian) dolostones, and was deposited during a transgressive phase of the second Middle Triassic transgression onto the southern Poland. The package consists largely of: 1) unfossiliferous dolosiltites and fine-grained dolarenites, the tops of which commonly contain root molds and small-scale karstic forms; 2) breccias (minor conglomerates) with lithoclasts of Givetian dolostones; 3) dolocretes; and 4) dolomitic shales. This lithofacies association represents a restricted lagoon which experienced longer periods of emersion. A minor occurrence of cryptalgal laminites reflects only temporary sedimentation in the intertidal zone of a tidal flat. The bone fragments occur within all types of lithofacies, but the macroscopically distinguishable specimens have been found exclusively in the dolocretes. The poor preservation and advanced disarticulation of bones hinder unequivocal assessment of their affinity. The small size of bones suggests that they represent prolacertiforms (perhaps juvenile Macrocnemus) or other small archosauromorphs similar in sizes to Protorosaurus or Czatkowiella whose remains were found in the 1950s within cave deposits, in the same outcrop. Macrocnemus widely inhabited Middle Triassic lagoons and tidal flats across Paleo-Europe and thus seems to fit well to the peritidal setting surrounding the “Stare Gliny” paleoisland. The bone-bearing package occurs 30 metres below the 5-m-thick oncolitic package that is widely regarded as a correlation horizon over the entire Kraków-Silesia region, and 15 metres below the sequence boundary marking the top of the Górażdże Beds in the Opole region and the Olkusz Bedsin the Kraków-Silesiaregion.On the basis of the secor relations,a conclusion can be made that the vertebrate assemblage is Bithynian/Pelsonian (middle Anisian) in age.

Opis:

A field survey has been conducted for the study area using the Global Positioning System (GPS) and geological and geomorphological maps of the area. The study area is one of the important areas in Iraq characterized by scarce water resources. The purpose of the study is to determine the hydro-chemical processes and their relationship to groundwater quality carried out in the southwestern desert region of Iraq, where the region lacks extensive studies of water resources. Twenty-eight groundwater samples were collected from wells distributed between the eastern borders of Saudi Arabia and the West Bank of the Euphrates River. For the purpose of hydrogeochemical analyses, the Fetter method was used to collect and examine samples. A large part of the recharge area is located in Saudi Arabia, where the groundwater bearing aquifer represented by the Dammam formation extends to Iraq and Saudi Arabian International borders. The analysis determined the order of cations (Na+ > Ca2+ > Mg2+ > K+) and anions (Cl– > SO42– > HCO3–). High values of the variation coefficient (CV) correspond to the concentration of potassium, sodium and chloride ions (CV: 68.7, 64.7 and 64 respectively). To identify the hydrochemical water facies, the Piper diagram was used. It was found that 53% of the water samples belong to the Na-Cl type and 40% are of the Ca-Mg-Cl type, while the rest of the samples are the Ca-Cl type. To identify geochemical processes, it was found that ion exchange processes via chloroalkaline indices 1 and 2 are prevalent between Ca2+, Mg2+ in the groundwater and Na+, K+ in water bearing rocks. To learn more about the processes that led to the concentration of certain ions, such as sodium, it was found that they tend to be of silicate minerals related to surface runoff of water in recharge areas and carbonic rocks. It was also found that rock / soil-groundwater interaction and evaporation processes were the formal processes in the saturated zone and evaporation in the unsaturated zone are prevalent processes of groundwater ion concentration.

Sandstones and conglomerates, which northwards of Brno agglomeration build a hill (ridge) named Babí lom are strongly diagenezed (anchi-metamorphozed) and tectonically deformed. Their regional distribution and stratigraphic position between the Cambrian(?) clastics and Upper Devonian limestones, as well as their appearance meant that they age is considering as Middle Devonian. They are distinguished as the so-called „Basal Devonian Clastics“. Almost all primary sedimentary features are well preserved and distinct. In the metasediments of the Babí lom hill were distinguished both the facies and structures typical of alluvial fans and rivers. Among others they are channel lags with imbricated grains, cross beddings and debrites. Within sedimentary association was established the way-up direction what clearly evidences a coarsening upwards sequence. Assuming the lack of rotation of series of sediments in the X-Y plane, the palaeotrasport was toward the north while major supply with material was from the east.

Opis:

The Sołtyków exposure is an old, long time abandoned clay pit. This exposure became known as a classical outcrop of alluvial-lacustrine deposits. Floral remains point to the earliest Jurassic (Lias 1-2) age, and the sequence stratigraphic correlation allows to narrow its age range to the Early Hettangian (Planorbis biochronozone). Sołtyków exposure fits the avulsion-controlled (crevassing- anastomosing) fluvial sedimentation model, however, some features such as laterally-accreted bedding point also to presence of high-sinuosity/meandering streams. Relatively thick and individualised package of lacustrine deposits occurring in the Sołtyków outcrop points to some permanency of the lake/swamp area during deposition of the sediments visible in the outcrop. Palaeosols are both of Podzol and Histosol type. The plant fossils in the Sołtyków exposure are very abundant and well preserved. The list of plants includes Neocalamites, the matoniacean, osmundacean and other indeterminate ferns, as well as pteridosperms, benettitaleans and conifers. Non-marine trace fossils comprise Coprinisphaera, Scoyeniaand aquatic Mermia ichnofacies. Other fossils that occur in Sołtyko?w are represented by Unionidae freshwater bivalve assemblage, insect remains, fresh-water ostracodes and scales of palaeoniscid fish. The Sołtyków exposure is well known Early Jurassic tracksite with numerous dinosaur footprints, mainly left by theropods and sauropods, and early mammalian footprints. The dinosaur nesting ground was also described. Recently, the Sołtyków exposure has been declared a natural reserve. Nature conservation problems are discussed. Due to many unique finds in Sołtyków (the oldest known evidence of gregarious ethology of dinosaurs, the biggest known Early Jurassic theropod footprints, rich and well-preserved invertebrate ichnoforms and plant remains, this exposure should be enlisted on the UNESCO World Heritage List (in geological cathegory). Moreover, the idea of “Kamienna Valley” geopark, comprising Sołtyków and other valuable outcrops in the region, is introduced.

Opis:

The present paper discusses a palaeoenvironmental interpretation of the Oligocene Ogwashi Formation (Niger Delta Basin, Nigeria) through morphometric analysis of pebbles, a research method essentially depending on the quantitative evaluation of pebble size and shape which change during transport processes in a range of depositional environments. The relationship of bivariate and ternary-diagram plots of independent functions was determined from freshly exposed sandstone sections in quarries at Ibusa, near Asaba, Nigeria. The grain size of pebbles ranges from fine (11.00 mm) to very coarse (41.33 mm), with a mean size of 21.05 mm (coarse pebbles). A bivariate plot of the flatness index vs maximum projection sphericity index shows 37% of the pebbles to fall within a beach (marine) environment, and 33% within a fluvial environment; the remaining 30% are uncertain. The maximum projection sphericity index vs oblate-prolate index bivariate plot indicates that 47% of pebbles fall within a marine environment and 22% within a fluvial environment, while the remaining 31% are uncertain. The sphericity-form ternary diagram plot shows that the pebbles primarily comprise bladed, platy, very bladed and very platy of near-equal proportions with minor elongate and very elongate stones, which suggests that the pebbles are diverse in origin. The sphericity-form bivariate plot indicates that the pebbles are largely of disc and blade shapes with a minor number of spherical and rod shapes. The near-equal proportion of pebbles in different segments of the bivariate and ternary diagram plots, and the wide distribution of the pebble grain sizes and shapes suggest the Ogwashi Formation is composed of redeposited sediments that likely were transported and deposited in a mix of marine and fluvial settings with possible transitional environments. In other words, the pebbles can be interpreted as marine-influenced fluvial sediments in marginal-marine settings.

Opis:

The article presents the facies and environment of the Upper Oligocene sediments in the area of block 09-2/10 based on the analysis of seismic facies and well data of the neighboring areas. The results of the interpretation of seismic data indicate that the upper Oligocene sediments are limited by the top C, top D seismic reflectors. The environment is formed from lagoons, lakes to deep lakes. Seismological facies analysis identified 03 facies including seismic facies with medium to poor reflection amplitude, medium continuous, low frequency reflecting the lacustrine sediments (80%) in most of the lake center. Strong reflective seismic facies, sigmoidal clinoforms reflect the lakeside sediments (15%) distributed in the lakeside shelf. The seismic facies with average and continuous amplitude poorly reflect alluvial sediments (5%) in the Northwest region. The direction of sediment transport is mainly from the Northwest and Southwest in the area. The sandstone sequences are distributed on the slopes of the lake and the lake bottom, which is potential reservoir.

Opis:

Main Late Devonian placoderm taxa known from the Holy Cross Mountains are characterised. The distribution of the Late Devonian placoderm fossils is described. Variation in their occurrences depend on the sedimentation environment of the rocks which contain fossils of this group. Connections between the Holy Cross Mountains placoderms development and the synsedimentary tectonic processes active in this area during the Late Devonian is discussed, and the local faunas compared to classic assemblages of the same age from Latvia.

Opis:

The present study establishes a lithostratigraphic subdivision, a bio- and chemostratigraphy and describes the sedimentology of the Alstatte Bay at the southern margin of the Lower Saxony Basin in northern Germany. The socalled Fischschiefer is developed in the lower part of the section, a 2.1 m thick laminated interval that shows TOC values of up to 2 % and is interpreted as local expression of the global Oceanic Anoxic Event 1a (OAE 1a). The basal part of the Fischschiefer is fairly continuously laminated, whereas its upper part is characterized by an alternation of laminated and non-laminated beds. Stable carbon isotopes ([delta^13]C[carb]) show a characteristic pattern for the Fischschiefer interval that can be correlated with sections from the Tethyan Realm. Immediately above the Fischschiefer, however, the studied section might reveal a diagenetic overprint as indicated by very negative carbon stable isotope values. The remaining part of the section is characterized by a rather monotonous claystone succession, terminated by a greenish layer rich in glauconite overlain by glacial till of Pleistocene age. The fauna is typically Boreal in the lower part of the section, but changes around 2 m above the Fischschiefer towards an assemblage indicating a distinct Tethyan influx. The faunal shift is considered to be due to the maximum flooding of the continuous, long-term sea level rise of the Early Aptian which led also to a supposed shift from a restricted to open bay environment.

Opis:

Złoże rud miedzi na monoklinie przedsudeckiej tworzą skały osadowe zdeponowane na przełomie czerwonego spągowca i cechsztynu (perm). Powstanie mineralizacji miedziowo-srebrowej jest związane z długotrwałymi i kilkuetapowymi procesami geologicznymi. Zagadnienie genezy złoża jest szeroko opisywane w literaturze jako zbiór następujących po sobie procesów sedymentacyjnych, diagenetycznych i tektonicznych. Parametry geologiczne złoża charakteryzują się znaczną zmiennością pionową i poziomą wynikającą ze zróżnicowania wykształcenia litologicznego skał złożowych oraz intensywności okruszcowania. Jednym z głównych czynników, które zdecydowały o poziomym rozprzestrzenienie siarczków miedzi w piaskowcach, łupkach i dolomitach miedzionośnych były warunki geochemiczne w jakich następowały kolejne fazy diagenezy skał osadowych.. Obserwowane obecnie granice facji utlenionej i redukcyjnej (niekiedy wyróżniana jest też facja przejściowa) są nieregularne i nieostre. Prowadzenie racjonalnej gospodarki zasobami złoża w strefach kontaktu facji geochemicznych wymaga stałego dozoru geologicznego oraz bardzo szczegółowego opróbowywania i kartowania przodków i ociosów wyrobisk. Autorzy podjęli próbę scharakteryzowania fragmentu obszaru złoża bilansowego oraz sąsiadującej z nim strefy bezzłożowej, związanej z obecnością czerwonych plam (rote Fäule) w południowej części złoża Sieroszowice.
The copper ore deposit of Foresudetic Monocline comprise the sedimentary rocks formed in the turn of Rotliegend and Zechstain (Permian). The origin of copper-silver mineralisation is involved with long and multistage geological processes. The issue of origin is widely described in literature as the series of sequential sedimentary, diagenetic and tectonic processes. The ore body is variable in horizontal and vertical direction which caused by different lithology of hosting rocks and mineralisation intensity. One of the main factors which determine the horizontal spread of mineralisation in sandstones, shales and dolomites is geochemical variability. The boundaries of oxidized and reduced facies are irregular and indistinctive. The mining extraction of the deposit in areas of the contact of oxidized and reduced facies requires the permanent geological supervision and detailed sampling and surveying. The authors make the attempt to document the deposit boundaries in area of red staining (Rote Fäule) in the southern part of Sieroszowice deposit.

Opis:

W profilu środkowego żywetu w regionie łysogórskim w Górach Świętokrzyskich, pomiędzy węglanowymi i iłowcowymi osadami warstw skalskich a wapieniami biostromalnymi warstw pokrzywiańskich lub iłowcami warstw nieczulickich występują silikoklastyczne osady warstw świętomarskich, w obrębie których wyróżniono sześć facji: piaskowce średnio- i gruboławicowe, piaskowce wapniste i mułowce, piaskowce i mułowce zaburzone sedymentacyjnie, piaskowce osuwiskowe, mułowce i cienkoławicowe piaskowce oraz mułowce. Obecność spływów grawitacyjnych w postaci piaskowców osuwiskowych i utworów typu derbis flow i mud flow, którym towarzyszą średnio- i gruboławicowe piaskowce utworzone w strefach kanałowych, wskazuje na podmorską depozycję na nachylonym dnie, w środowisku skłonu basenu. Sedymentacja warstw świętomarskich przebiegała na obszarze głębszego szelfu w proksymalnej i dystalnej części prodelty, należącej prawdopodobnie do średniej wielkości systemu deltowego. Wskaźniki pulsacyjnej sedymentacji piaskowców cienkoławicowych oraz obecność szczątków roślinnych w mułowcach wskazują na transport materiału terygenicznego głównie przy udziale generowanych przez rzeczne powodzie przepływów hiperpyknalnych (hyperpycnal flow). Materiał terygeniczny warstw świętomarskich był dostarczany do basenu łysogórskiego z południowego wschodu. Sedymentacja warstw świętomarskich jest związana ze wzrostem tektonicznej subsydencji środkowodewońskiego basenu w regionie łysogórskim Gór Świętokrzyskich. Równowiekowe osady silikoklastyczne rozpoznane na obszarze południowo-wschodniej Polski i zachodniego Wołynia na Ukrainie związane są prawdopodobnie z depozycją w obrębie tego samego systemu deltowego.
The middle Givetian section of the Łysogóry region of the Holy Cross Mts (HCM) is highlighted by the presence of siliciclastic sediments of the Świętomarz Beds that occur between carbonate and clayey sediments of the Skały Beds and biostromal limestones of the Pokrzywianka Beds or claystones of the Nieczulice Beds. The Świętomarz Beds comprise six facies: (1) medium- and thick-bedded sandstones, (2) calcareous sandstones and siltstones (3) sedimentary disturbed sandstones and siltstones, (4) slump sandstones, (5) siltstones and thin-bedded sandstones, (6) siltstones. The presence of gravitational flows in the form of slump sandstones and debris and mud flows, which are associated with medium- and thick-bedded sandstones linked to channel zones, indicate submarine deposition on an inclined floor within a basinal slope environment. Deposition of the Świętomarz Beds occurred in an area of deeper shelf within the proximal and distal parts of prodelta that belonged to a medium-sized delta system. Indications of pulsating sedimentation of thin-bedded sandstones and the presence of plant remains in siltstones point up to transport of terrigenous material primarily by hyperpycnal flows generated by river floods. Terrigenous material of the Świętomarz Beds was derived to the Łysogóry basin from the southeast. Sedimentation of the Świętomarz Beds is closely linked to the increased tectonic subsidence of the Middle Devonian basin in the Łysogóry region of HCM. Coeval siliciclastic sediments, which have been identified in the area of south-eastern Poland and western Volhynia in the Ukraine, are presumably related to deposition within the same delta system.

Opis:

The Upper Cretaceous of the Elbe Valley in Saxony and the erosion outliers west of it mark an Upper Cretaceous NW-SE-running strait between the Westsudetic Island in the NE and the Mid-European Island to the west. This street connected the NW-German-Polish Basin in the north and the Bohemian Cretaceous Basin (and adjacent regions of the Tethys) in the south. However, post-Cretaceous erosion north of Meißen removed any Upper Cretaceous deposits but erosion outliers at Siebenlehn and especially north of the Forest of Tharandt proof the presence of a marly through silty belt in this area. Three transgressions (base of uppermost Lower to Middle Cenomanian, base of Upper Cenomanian and base of the geslinianum Zone in the mid-Upper Cenomanian) have taken place. The sedimentation was influenced by the topography of the mentioned islands and by movements at structural lines in the Proterozoic and Palaeozoic basement. During the early Late Cenomanian, a marly-silty sedimentation (Mobschatz Formation) in the north existed besides sandy sedimentation in the south (Oberhäslich Formation). The transgression at the base of the geslinianum Zone caused the final submergence of island chains between Meißen, Dresden and Pirna, and a litho- and biofacies bound to cliffs and submarine swells formed. A silty-marly lithofacies, a mixed sandy-silty lithofacies (Dölzschen Formation) and a sandy lithofacies in the south (Sächsisches Elbsandsteingebirge) co-existed during the latest Cenomanian. The first mentioned biofacies yields a rich fauna mainly consisting of oysters, pectinids, rudists, and near-shore gastropods accompanied by echinids and, in some cliffs, teeth of sharks. The Pennrich fauna (Häntzschel 1933; Uhlig 1941) especially consists of the very common serpulids Pyrgopolon (P.) septemsulcata and Glomerula lombricus (formerly Hepteris septemsulcata and G. gordialis).

Opis:

The extreme north-eastern Algeria, in particular the Guelma city conceals thermal springs, whose waters circulating at great depths allow the rain-waters to warm up (according to the average geothermal gradient of 1°C per 33 m) and to acquire a mineralization which depends on the traversed rock. The goal of this research work was to determine mineralization origin of the thermo-mineral waters of Hammam Meskoutine (Algerian N-E). A hydro-chemical study involved analyses of a number of physical and chemical parameters of waters such as: temperature, hydrogen potential, electrolytical conductivity, Cl^–, SO₄ ^2–, HCO₃ ^–, Ca²⁺, Mg²⁺, K⁺ and Na⁺. The data processing on the diagram revealed two dominating chemical facies: sulphate-magnesium and bicarbonate magnesium. With a high conductivity in excess of 2300 μS∙cm^–1, the temperature reaches 97°C. Calculation of the saturation index shows that the waters are supersaturated in carbonate minerals (calcite, dolomite and aragonite) and less saturated with evaporite minerals (halite, anhydrite, sylvite and gypsum). The reconstitution in dissolved salts reveals a dominant salt rich in calcium bicarbonates, in calcium sulphates and secondarily in magnesium salts. Geological sections used in the study zone affirm that the chemical composition of the spring waters comes from the neritic limestone dissolution and the gypso-saline complex of Hammam Meskoutine.
Północnowschodnia Algieria, w szczególności okolice miasta Guelma, obfitują w źródła termalne, których wody krążące na dużych głębokościach powodują ogrzanie wód deszczowych (o 1°C na 33 m zgodnie ze średnim gradientem geotermalnym) i poziom mineralizacji zależny od podłoża skalnego. Celem badań było ustalenie mineralizacji w wodach termalno-mineralnych Hammam Meskoutine (północnowschodnia Algieria). Badania hydrochemiczne obejmowały analizę wybranych parametrów fizycznych i chemicznych, takich jak: temperatura, pH, przewodnictwo elektrolityczne i stężenie Cl^–, SO₄^2–, HCO₃ ^–, Ca²⁺, Mg²⁺, K⁺ i Na⁺. Przetworzenie danych na diagramie ujawniło istnienie dwóch facji chemicznych – siarczanowo-magnezowej i wodorowęglanowo- -magnezowej. Przewodnictwo wód przekraczało 2300 μS∙cm^–1, a temperatura osiągała 97°C. Wyniki obliczeń wskaźnika wysycenia świadczą, że wody były przesycone minerałami węglanowymi (kalcyt, dolomit i aragonit) i mniej wysycone minerałami, takimi jak: halit, anhydryt, sylwit i gips. W składzie chemicznym dominują sole bogate w wodorowęglan i siarczan wapnia, a w mniejszym stopniu występują sole magnezu. Przekroje geologiczne analizowane w niniejszych badaniach potwierdziły, że skład chemiczny wód źródlanych jest skutkiem rozpuszczenia wapieni i gipsowo-solnego kompleksu typowego dla regionu Hammam Meskoutine.

Opis:

Sedimentological analysis of the Early Jurassic Höör Sandstone in Central Scania, Sweden shows that two units representing different lithofacies may be distinguished. The lower Stanstorp Member is characterised by texturally and mineralogically heterogeneous sediments. Mature arenites and immature quartz and subarkosic wackes form two clearly separated groups, interpreted as fluvial channel and alluvial plain deposits respectively. The fluvial character of this member is supported by a dominance of unidirectionally oriented trough sets, abundant plant detritus, the presence of plant roots and palaeosols and a lack of marine body fossils and trace fossils. An intercalated composite polymict conglomerate layer is interpreted as the result of an extraordinary flood. The overlying Vittseröd Member is characterised by mature quartz arenites and large-scale tabular sets with multidirectional orientations. The Vittseröd Member arenites are of storm- and possibly tide-dominated shoreface origin. Bidirectional wave and tide-induced longshore currents and unidirectional onshore migration of sand ridges were the chief depositional processes. Longshore currents towards the NNW prevailed. Upper flow regime features, and erosion and reworking of sediments are attributed to the storm-induced rip currents. Lithofacies characteristics are used to define the following lithostratigraphical units: the Stanstorp and the Vittseröd members, as well as the Höör Sandstone (Fm) above. Lithofacies and palaeoenvironmental characteristics of the Vittseröd Member and their comparison with the facies of the Helsingborg and Döshult members in Western Scania suggest a Sinemurian age for the Vittseröd Member.

Opis:

Przedmiotem opracowania są warstwy krośnieńskie odsłaniające się w oknie tektonicznym Mszany Dolnej w obrębie jednostki dukielskiej. Utwory te wykształcone są głównie w litofacji piaskowców, piaskowców z mułowcami, mułowców z piaskowcami oraz mułowców. Podczas analizy sprofilowanych odsłonięć brano przede wszystkim pod uwagę następujące cechy: wykształcenie litofacjalne, miąższości ławic, procentowy udział piaskowców w stosunku do skał zbudowanych z frakcji drobniejszych, wysortowanie materiału okruchowego, a także rodzaj powierzchni spągowych i stropowych ławic oraz obecność sekwencji negatywnych i pozytywnych w profilu. W konsekwencji rozpoznano środowisko sedymentacji tych utworów. Wykazano, że warstwy krośnieńskie powstawały w obrębie głębokomorskich stożków, w strefie stożka zewnętrznego, w subśrodowisku lobów depozycyjnych, obrzeżenia lobu i obrzeżenia stożka. Na podstawie próbek mikrofaunistycznych oznaczono wiek warstw krośnieńskich na oligocen (zona NP24). Pomierzone kierunki paleotransportu wskazują, że transport materiału okruchowego odbywał się z kierunku południowo-zachodniego na północny wschód.
The present author studied the Krosno beds outcropped in the Mszana Dolna tectonic window within the Dukla Unit. These deposits are mainly developed as sandstones, sandstones with mudstones, mudstones with sandstones and mudstones. The following features: lithofacial development, thickness of layers, the percentage of sandstones in relation with the fine-grained rocks, clastic sediments sorting as well the character of bottom and top surfaces of layers and the presence of the positive and negative sequences in a profile were taken into account for the analysis of the geological profiled outcrops. Such sedimentological features of the Krosno beds indicate their depositional environment connected with the deep-sea fans, in the area of the lower fan, in the subenvironment of the depositional lobes, the lobe fringe and the fan fringe. Based on the microfossils the age of the Krosno beds has been indicated as Oligocene (zona NP24). The measured directions of the palaeotransport show that the distribution of the clastic material took place from the SW to the NE.

Opis:

Badania przeprowadzono na obszarze Karpat zewnętrznych (w przygranicznym rejonie Polski, Słowacji i Ukrainy). Rozpoznano charakter facji anoksycznych w Karpatach na obszarze Polski i Słowacji w obrębie różnych jednostek tektonicznych od dukielskiej przez śląską, węglowiecką, skolską aż po borysławsko-pokucką. Analizę oparto na parametrach geochemicznych i wskaźnikach stanowiących wyniki badań metodą Rock-Eval, chromatografii gazowej alkanów i izoprenoidów oraz oznaczeń izotopów stabilnych węgla (dla materii organicznej). Stwierdzono zróżnicowanie poszczególnych wartości. Zawartość TOC zmienia się w przedziale od 0,62% do powyżej 8,7% wag., przy czym najwyższe wartości charakteryzują facje jednostki skolskiej. Potencjalna macierzystość utworów jest bardzo dobra w obrębie facji anoksycznych jednostki skolskiej, centralnej depresji karpackiej i jednostki dukielskiej. Rezydualny potencjał (S2) rozproszonej materii organicznej zmienia się od 0,26/1,20 mg HC/g skały w warstwach dolnokredowych w Łusce Bystrego do 16,50/36,59 mg HC/g skały w jednostce skolskiej (Bandrów). Jest on umiarkowany w segmencie polskim i słowackim jednostki dukielskiej i nieco wyższy w jednostkach magurskiej i borysławsko-pokuckiej. Frakcja alifatyczna dominuje we wszystkich badanych skałach przy stosunkowo homogenicznym składzie frakcji alifatycznej bituminów. Rozkład n-alkanów jest zmienny. Można wyróżnić trzy grupy bituminów o zróżnicowanej dominacji n-alkanów krótkołańcuchowych i/lub n-alkanów długołańcuchowych. Pristan na ogół dominuje nad fitanem, przy czym izoprenoidy często mają stężenie niższe w stosunku do sąsiadujących z nimi n-alkanów C17 i C18. Stosunek pristan–fitan zmienia się od 18,01 (centralna depresja karpacka) poprzez 13,36 (jednostka węglowiecka) do 6,36 (jednostka śląska), podczas gdy w pozostałych rejonach jego wartość jest bliska jedności. Wśród węglowodorów aromatycznych przeważa fenantren i jego metylowe i di-metylowe pochodne. Wartości oznaczeń δ13CPDB dla węglowodorów wykazują niewielkie zróżnicowanie dla poszczególnych frakcji. Dla bituminów zmieniają się od –24,9 do –28,9‰. Dojrzałość termiczna kerogenu (typ mieszany od II do III) zmienia się od fazy niedojrzałej (jednostka skolska i borysławsko-pokucka) przez dojrzałą w jednostce śląskiej i dukielskiej, po fazę wczesnego okna gazowego w strefie melanżu tektonicznego i jej sąsiedztwie.
Studies were conducted in the Outer Carpathians in the area of the Western and Eastern Carpathians in the borderland of Poland, Slovakia and Ukraine. The character of anoxic facies in the Carpathians in the Polish and Slovak area within different tectonic units - from the Dukla unit through the Silesian, Boryslav-Pokuttia, Skole and the Węglówka units was analyzed. The analysis was based on geochemical parameters and indices from the following methods: Rock-Eval analysis, gas chromatography of n-alkanes and isoprenoids, isotopic determinations of carbon isotopes (in organic matter). Diversity of parameters has been stated. In case of bitumens, the TOC content changes within the interval from 0.62% to over 8.7wt %, while the highest values characterize the facies of the Skole unit. The potential maturity of the sediments is very high in the anoxic facies of the Silesian and Dukla units and in the Central Carpathian Depression (CDK). Residual petroleum potential (S2) of the dispersed organic matter varies from 0.26/1.20 mg HC/g rock in the Lower Cretaceous strata of the Bystre Slice to 16.50/36.59 mg HC/g rock in the Skole unit (Bandrów). It is moderate in the Polish and Slovak segments in the Dukla unit and slightly higher in the Magura and Boryslav-Pokuttia units. The aliphatic fraction dominates in all the studied rocks, while the aliphatic composition of bitumens is relatively homogeneous. The n-alkane distribution is variable in the rocks and solid bitumens. Three groups of bitumens may be distinguished with a variable domination of short-chain n-alkanes and/or long-chain n-alkanes. In general, pristane predominates over phytane, while the isoprenoids often show a lower content in comparison to the adjacent C17 and C18 n-alkanes. The pristine - phytane ratio oscillates from 18.01 (Central Carpathian Depression – CDK) through 13.36 (Węglówka unit) to 6.36 (Silesian unit), being close to one in other samples. Among the aromatic hydrocarbons, phenantrene predominates together with its methyl and di-metlyl derivatives. The d13CPDB data for hydrocarbons show some variability for different fractions. For bitumens, they change from –24.9 to –28.9‰. Thermal maturity of kerogen (mixed type from II to III) varies from the immature phase (Skole and Boryslav-Pokuttia units) through mature in the Silesian and Dukla units up to the early gas phase in the tectonic mélange and its neighbourhood.

Opis:

The Rotliegend Basin is filled with terrigenic complex over 1200 m in thickness. The complex comprises sediments of eolian, fluvial and playa depositional systems (Fig. 1). Reservoir volume of the pore space accessible for the reservoir media is ca. 830-990 km3. Gas exploration in this stratigraphic unit is now focused at depths of around 3000-3800 m b.s.l., in the near-top zone. Poor reservoir properties, especially permeabilities, are here the limiting factor for conventional exploration. A change in the prospecting strategy to comprise tight gas targets moves research into the deeper zone covering the whole profile of the Rotliegend. The paper presents preliminary results of 3D modeling of lithofacies and related petrophysical parameters variability. The static model was created with the use of Petrel 2009.2. Structural framework was built using regional structural, isopach and facies maps. It was relatively detailed, comprising 9 576 000 cells organized in 3 zones and 60 layers. To estimate facies model, the authors used results of integrated environmental analysis of core data and logs from 117 wells (Fig. 2 ). Models of clay content (Vsh) and porosity (PHI) were based on logs from 75 wells. The obtained results show that the northern margin of the Eastern Erg is characterized by presence of numerous eolian strata with porosity ranging from 5 to 15%. Their quality, quantity and thickness decrease toward the north, along with increase in depth. Modeling results indicate that the dominating porous layers of eolian sandstones and fluvial inserts are often intercalated with "non-reservoir" layers revealing porosity below 5%. In this zone, a deeper part of the Rotliegend section should be investigated more thoroughly (Fig. 5, 6, 9). The Pomeranian sector of the Central Basin is dominated by playa and fluvial sediments (Fig. 7, 8, 10). Slightly clayey eolian strata make a few, laterally discontinuous intercalations. Gas accumulations could be expected within local, laterally confined interlayers of eolian and fluvial sandstones with porosity of around 5-12%. Due to the location in the near-base part of the Rotliegend section, close to Carboniferous source rocks, they may be filled with gas, forming so-called sweet spots. Probability of gas occurrence in Pomerania is high as indicated by the Międzyzdroje gas field or small accumulation found in Piaski-PIG2 well. The presented preliminary study allowed to test usability of 3D modeling in tight gas prospecting. Fully reliable results will be obtained after increasing precision of the models comprising detailed seismic interpretation, the use of seismic attributes, and inclusion of quantitative data in diagenetic processes and sedimentology of layers in the modeling process.

Opis:

Sedimentological analysis of the Missão Velha Formation (Araripe Basin, northeast Brazil) is the aim of this paper through detailed facies analysis, architectural elements, depositional systems and paleocurrent data. The main facies recognized were: (i) coarse-grained conglomeratic sandstones, locally pebbly conglomerates, with abundant silicified fossil trunks and several large-to-medium trough cross-stratifications and predominantly lenticular geometry; (ii) lenticular coarse-to-medium sandstones with some granules, abundant silicified fossil wood, and large-to-medium trough cross-stratifications, cut-and fill features and mud drapes on the foresets of cross-strata, (iii) poorly sorted medium-grained sandstones with sparse pebbles and with horizontal stratification, (iv) fine to very fine silty sandstones, laminated, interlayered with (v) decimetric muddy layers with horizontal lamination and climbing-ripple cross-lamination. Nine architectural elements were recognized: CH: Channels, GB: Gravel bars and bed forms, SB: Sand bars and bedforms, SB (p): sand bedform with planar cross-stratification, OF: Overbank flow, DA: Downstream-accretion macroforms, LS: Laminated sandsheet, LA: Lateral-accretion macroforms and FF: Floodplain fines. The lithofacies types and facies associations were interpreted as having been generated by alluvial systems characterized by (i) high energy perennial braided river systems and (ii) ephemeral river systems. Aeolian sand dunes and sand sheets generated by the reworking of braided alluvial deposits can also occur. The paleocurrent measurements show a main dispersion pattern to S, SE and SW, and another to NE/E. These features imply a paleodrainage flowing into the basins of the Recôncavo-Tucano-Jatobá.

Wieloletnie badania nad związkiem między występowaniem strefy utlenionej Rote Faule a bogatą mineralizacją kruszcową pozwoliły na stwierdzenie prawidłowości w rozmieszczeniu złóż miedzi i srebra w bezpośrednim otoczeniu facji utlenionej. W województwie lubuskim hipotetyczna strefa kontaktu pomiędzy dwiema głównymi facjami geochemicznymi przebiega w kierunku NW-SE na północny wschód od Zielonej Góry do Nowej Soli. W zasięgu omawianej strefy wyznaczono rozległy na 484 km2 obszar prognostyczny Mozów. W omawianym rejonie mineralizację w utworach cechsztyńskiej serii miedzionośnej zbadano dotychczas w siedmiu dostępnych archiwalnych otworach wiertniczych, gdzie na głębokości od 2000 do 2500 m ponad skałami utlenionymi odnotowano bogatą mineralizację kruszcową. Badany obszar stał się poligonem dla zastosowania nowych technik poszukiwawczych rud. Wyniki prac reinterpretacyjnych wybranych profili sejsmicznych 2D przy zastosowaniu efektywnych współczynników odbicia pozwoliły na szczegółowe rozpoznanie stref zmian litologicznych i miąższościowych poszczególnych cyklotemów cechsztynu oraz elementów tektonicznych związanych z tymi utworami. Uzyskano także bardziej precyzyjne kartowanie stropu czerwonego spągowca. Natomiast specjalne transformacje anomalii Bougera w tym rejonie wykonane w postaci map anomalii rezydualnych oraz map gęstości grawimetrycznych elementów liniowych o zasięgu regionalnym i lokalnym w wyznaczonych przedziałach głębokościowych umożliwiły odwzorowanie tektoniki i zmian litologicznych. Skupienie zbadanych otworów na nieznacznej części obszaru prognostycznego nie daje pełnego obrazu rozprzestrzenienia okruszcowania, niemniej uwzględniając zasadnicze prawidłowości występowania dolnocechsztyńskich ciał złożowych należy sądzić, że pas o wysokiej koncentracji miedzi przedłuża się w utworach łupka miedzionośnego oraz wapienia cechsztyńskiego po zachodniej stronie granicy redoks, jak i w łupku miedzionośnym i białym spągowcu po wschodniej stronie granicy redoks. Analizy dostępnych danych w pełni uzasadniają konieczność prowadzenia prac poszukiwawczo-badawczych w celu rozpoznania skali rozprzestrzenienia się ciała kruszcowego. W obrębie omawianego obszaru obecnie prowadzone są intensywne badania oraz prace wiertnicze.
Extensive research completed on the relationship between the oxidized Rote Faule zone and rich ore mineralization has allowed to link the presence of copper and silver deposits in the vicinity of oxidized facies. In the Lubuskie voivodship the hypothetical contact zone between two main geochemical facies runs in the NW-SE direction, northeast of Zielona Góra towards Nowa Sól. The extent of the discussed zone covers 484 km2 of the Mozów prognostic area. Within the discussed area, Zechstein Kupferschiefer mineralization has been investigated in seven available archival cores, where, at the depths between 2000 to 2500 meters above the oxidized rock, rich ore mineralization was observed. The investigated area became training grounds for ore prospecting using the newest methods. The results of reinterpreting of selected 2D seismic profiles by the use of the effective reflection coefficients allowed to detailed identification of lithological zone changes, and thicknesses of particular Zechstein cyclothems, as well as tectonic elements linked to them. Mapping of the top contact of the Rotliegendes was also completed. In addition, special transformations of the Bouguer anomalies compiled in the form of residual anomaly maps as well as gravimetric density maps of linear elements of regional and local extent at pertinent depth intervals allowed the trace of tectonic and lithological changes. The number of cores investigated in a small part of the prognostic area does not give a complete image of mineralization dispersion, however taking into consideration the basic trend in the occurrence of Lower Zechstein ore bodies, an assumption can be made that the belt of high copper concentrations extends into the Kupferschiefer and the Zechstein Limestone facies on the western border of the redox boundary, as well as in the Kupferschiefer and Weissliegendes facies on the eastern border of the redox boundary. Analyses of available data gives reason to conduct exploration and research in order to determine the dispersion of ore bodies. Within the boundaries of the discussed area, intensive research and drilling is being conducted.

Opis:

In the Ghibaudo (1992) classification, the Upper Jurassic Lower Cieszyn Shales (Vendryně Formation) exposed in Goleszów (southern Poland) show sedimentological features typical of the MyG (muddy gravel beds) facies. Two lithic components of this facies have been petrographically studied: calcareous shales, which are principal constituent of the olistostrome matrix, and the rocks displaying field characteristics of marls, which occur as olistoliths. Two factors controlling the mode of intrabasinal redeposition have been recognized: the primary depositional environment, and the presence of calcareous nannofossils in the original sediments. Because the rocks occurring as olistoliths and those forming the matrix are compositionally similar but differ in grain size and clay abundance, it is reasonable to assume that the matrix rocks were originally deposited in quieter water conditions than the future olistoliths. Despite post-sedimentary modification, FESEM/BS imagery of the marls from the olistoliths reveals coccoliths in their groundmass, which are hold together with calcite overgrowth cement; this feature is eogenetic. Thus, the presence of coccoliths appears to be the crucial factor that made possible early hardening of the sediments and subsequently their redeposition as lithic blocks. This process in the starting sediments for the olistostrome matrix was inhibited by clay. Thus, they remained unconsolidated and were then redeposited as muds.

Opis:

The Jurassic deposits which crop out in the quarries at Priborzhavske, Perechin and Novoselitsa in the Transcarpathian Ukraine comprise fairly similar successions, allowing their interpretation as corresponding to a single palaeogeographic zone in the Pieniny Klippen Basin. To the same zone belong also deposits from Beňatina quarry in eastern Slovakia. The following main stratigraphic units may be recognized: terrigenous and fleckenkalk-fleckenmergel deposits (Sinemurian-Pliensbachian), highly diversified and condensed deposits (uppermost Pliensbachian-Aalenian), crinoidal limestones (Bajocian, with a stratigraphical gap covering a lower part of the Lower Bajocian), nodular limestones of ammonitico-rosso type (uppermost Bajocian to Oxfordian with a possible gap covering the Callovian and Lower Oxfordian), well bedded micritic limestones (Kimmeridgian to Upper Tithonian), and bedded limestones with cherts of the maiolica type (from the uppermost Tithonian). Two rifting phases, well developed in the successions, took place: (1) Devín phase during latest Pliensbachian-Toarcian-and at least earliest Aalenian, and (2) Krasín phase during the Bajocian. The onset of pelagic deposits overlying the rift strata took place during the latest Bajocian, and corresponds well with the general subsidence and development of a more uniform facies pattern during the post-rifting time as everywhere in the Pieniny Klippen Basin. Selected ammonite taxa of the Lower and lower part of the Middle Jurassic are illustrated and discussed.

Opis:

Ground-penetrating radar (GPR) surveys and sedimentological outcrop analyses were combined in order to determine the reflection patterns and internal architecture of terrace deposits of the Vistula River at Kępa Zawadowska in the southern part of Warsaw (central Poland). The sedimentary analyses concerned the granulometric composition and lithofacies analysis. The 34 GPR profiles, which were obtained in two outcrops, using a Malå RAMAC/GPR system with 500-MHz and 250-MHz shielded antennas, were up to 100 m long. The most characteristic ground-penetrating radar profiles are presented; they show a high-resolution data set of radar facies. The GPR data suggest the presence of three geophysically different units, namely with high-angle inclined reflections (radar facies 1), with discontinuous undulating or trough-shaped reflections (radar facies 2), and with low-angle reflections (radar facies 3). The internal structure of the fluvial deposits was obtained by integration of the GPR and sedimentological data, which combination provides a more accurate visualisation of sedimentary units than do reconstructions that are based only on standard lithologic point data.

Opis:

The Kashkan Formation (?Palaeocene to Middle Eocene) in the Zagros fold-thrust belt, SW Iran, which is intercalated between to marine limestone formations, consists of conglomerates, sandstones and siltstones. The sedimentology and the palaeogeography of the Kashkan Formation had not received any attention thus far, but have now been studied in seven sections, situated in the province of Lorestan. The sediments form twelve lithofacies, three ichnosubfacies and seven architectural elements, which are described, depicted and analysed. The analysis leads to the conclusion that most sediments accumulated in a low-sinuosity, low-gradient braided-river system (characterised by mainly unidirectional palaeocurrent directions, and by sheetfloods), that occasionally showed meandering characteristics (represented by overbank deposits and large bars). The deposits of this system closely resemble those of the South Saskatchewan River in Canada, which is considered as the classical example of a sand-bed braided river. The river flowed roughly from North to South, as deduced by palaeocurrent indicators such as imbrication and large- to medium-scale trough cross-stratification (direction measured in the trough axes). This current direction is supported by the southward to south-westward thinning of the formation and by the diminishing average grain size in the same direction. The trace fossils in the Kashban Formation fit all in the Skoyenia ichnofacies, which has here three ichnosubfacies which allow a more detailed palaeoenvironmental reconstruction, indicating that the braided stream passed into the low-energy shoreface zone of a tidally-influenced sea.

Opis:

This study is a detailed lithofacies analysis of the Wiar and Leszczyny members of the deep-marine Ropianka Formation (Campanian–Paleocene) exposed in the Hucisko Jawornickie section of the Skole Nappe, Polish Carpathian Flysch. The sedimentary succession (>400 m thick) represents a channelized lobe complex that prograded at the base of submarine slope. Seven sedimentary facies are recognized as a record of the principal modes of sediment deposition. Based on their stratigraphic grouping and grain-size trends, six facies associations are distinguished as representing specific sub-environments of the depositional system: distributary channels, channel-mouth lobes, channel levees, crevasses and interlobe basin plain with crevasse splays. The individual facies associations are characterized statistically and their internal facies organization is analysed by the method of embedded Markov chains to reveal the time pattern of depositional processes. The environmental changes indicated by the vertical succession of facies associations are attributed to the autogenic processes of the distributary channel shifting within an aggrading lobe area and the lateral switching of depositional lobes. Eustatic influences are likely, but difficult to ascertain with poor biostratigraphic data. The bulk basinward advance of the base-of-slope system was probably due to a pulse of the tectonic narrowing of the synclinal Skole Basin.

Opis:

Dolnokredowe warstwy węglowieckie stanowią kolektor ropy naftowej i gazu w złożu Węglówka, które stanowi jedno z najwcześniej odkrytych złóż ropy w Karpatach fliszowych. W obrębie dwóch fałdów odsłaniających się w półoknie tektonicznym Węglówki zarejestrowano szereg profili warstw węglowieckich, w których zgodnie z metodyką analizy facjalnej opisano następujące litofacje: piaskowce zlepieńcowate (SC), piaskowce (S), piaskowce z mułowcami (SM), mułowce z piaskowcami (MS) oraz mułowce (M). Dla piaskowców wchodzących w skład litofacji SC, S i SM oznaczono gęstość pozorną i nasiąkliwość. Badania petrograficzne obejmowały obserwacje w mikroskopie optycznym i skaningowym oraz w katodoluminescencji, a także badania porozymetryczne i oznaczenia współczynnika przepuszczalności. Wyniki badań wskazują na dwa czynniki odpowiedzialne za korzystne właściwości zbiornikowe piaskowców węglowieckich. Pierwszy stanowi wczesna i ograniczona cementacja krzemionkowa, mająca istotne znaczenie dla opóźnienia postępu kompakcji i zachowania porowatości osadu w początkowej fazie diagenezy. Drugi czynnik to koncentracja cementu węglanowego w obrębie konkrecji. Bioklasty krzemionkowe oraz najdrobniejsze frakcje ziaren kwarcu stanowiły źródło mikrokrystalicznego cementu kwarcowego oraz cementu chalcedonowego. Lokalnie wysoka zawartość biogenicznej krzemionki była przyczyną obfitej cementacji chalcedonowej. Cementacja węglanowa przyczyniła się do znacznej redukcji tej przestrzeni porowej, jaka zachowała się po wcześniejszej kompakcji osadu i cementacji krzemionkowej. Cement węglanowy, jak również okruchy węglanowe rejestrowano tylko w obrębie konkrecji, podczas gdy w ich otoczeniu stwierdzono brak detrytycznego materiału węglanowego i cementu węglanowego. Zatoki korozyjne w ziarnach kwarcu i skaleni notowane w otoczeniu konkrecji stanowią ślady po pierwotnych węglanach. Proces powstawania konkrecji węglanowych w piaskowcach węglowieckich można uznać jako wczesnodiagenetyczny, przemawia za tym wysoka zawartość cementu węglanowego oraz luźne upakowanie ziaren szkieletowych w obrębie konkrecji. Stwierdzono, że główną rolę w kształtowaniu cech zbiornikowych odgrywa skład mineralny materiału okruchowego, który decyduje o kierunku przemian diagenetycznych i wykształceniu określonego zespołu spoiw, podczas gdy litofacje są mniej istotne dla ich właściwości kolektorskich.
The Early Cretaceous Węglówka Beds is the reservoir of the Węglówka Oil Field, one of the earliest discovered in the Outer Carpathians (exploitated since 1888). This region is the cradle of world oil exploration and petroleum industry. The Węglówka Beds form two anticlines within the half-window of the Sub-Silesian Unit. A sedimentological analysis of several sections revealed the following lithofacies of the subaqueous gravity flow: conglomeratic sandstones (SC), sandstones (S), sandstone-mudstone couplets (SM), mudstone-sandstone couplets (MS) and mudstones (M). Apparent density and water absorptivity were determined for 47 sandstone samples collected from the facies SC, S, SM. The 15 most differentiated samples were selected for further petrographic and diagenetic studies with optical and scanning electron microscopes, X-ray diffraction and cathodoluminescence. Furthermore, mercury injection curves and permeability coefficients were determined. The results of analyses indicate that two factors are responsible for the good/positive reservoir properties of the Węglówka Sandstone. The first factor is the early and limited siliceous cementation. Siliceous sponge spicules and very fine quartz grains were the source of sparse chalcedonie cement and microcrystalline quartz, which formed rims around the grains while pores remained free. Compaction was inhibited and initial porosity was preserved to a large extent. Stronger chalcedonie cementation and the reduction of porosity occurred only locally as the result of the high content of biogenic silica. The other factor is the carbonate cement, which occurs only in spots (concretions). Carbonate cementation brought about a large reduction of the pore space within the concretions, which survived compaction and siliceous cementation. Both carbonate cement and carbonate detrital material were observed only within concretions. Corrosion of quartz and feldspars was the only trace of primary carbonates in their close vicinity. In turn, the abundance of the carbonate cement and a loose grain framework in the carbonate concretions was the evidence of the early origin of concretions. The study has revealed that the mineral composition of the detrital components controlled the diagenesis and formation of specific assemblages of cements and thus played the main role in modelling the reservoir properties of the Węglówka Sandstone. Those properties were controlled by the sedimentary conditions (facies) to a far lesser extent.

Opis:

The Early Kimmeridgian of the Wieluń Upland and adjoining regions, after the decline of sedimentation of the deep-neritic sponge megafacies (Częstochowa Sponge Limestone Fm.) and associated limestones and marls with poor benthic fauna (Pilica Fm.) during the Planula Chron, showed the subsequent development of moderately shallow-water biostromal chalky limestones with siliceous sponges and corals, replaced laterally by micritic limestones and marls (Prusicko Fm.) during the Platynota Chron and the earliest Hypse¬locyclum Chron. Towards the north and south shallow-marine carbonate platforms occurred (represented by deposits of the “oolitic” fm.), whereas towards the north-west and west deeper marine facies, represented initially by limestones with siliceous sponges (Częstochowa Sponge Limestone Fm.), and later during the Hypselocyclum Chron by bedded limestones and marls with ammonites (Burzenin Fm.) were deposited. This palaeogeographic pattern was controlled by the synsedimentary tectonics. The detailed biostratigraphical classification of the deposits studied from the Platynota to the Divisum zones, and their lithological character, enable the recognition of the primary sedimentary cyclicity by comparison with the well dated short eccentricity cycles in the coeval succession of south-eastern France. The two appendixes enclosed give the characteristics of: (1) the characteristics of the ammonite faunas especially of the families Ataxiocerati¬dae and Aulacostephanidae (where two new species are established – Balticeras samsonowiczi sp. nov., and Rasenioides glazeki sp. nov.); (2) the newly established lithostratigraphical units: the Prusicko Fm., and the Burzenin Fm., and the smaller rank units (members, beds) recognized therein.

Opis:

The Polish Carpathian Foredeep Basin (PCFB) is the northern compartment of a foreland basin system that surrounds the Carpathian orogenic belt. The axis of the eastern part of the PCFB plunges gently towards SE, where the Miocene basin-fill succession exceeds 2000 metres in thickness. The Miocene succession developed in shallow marine ramp settings and is subdivided into 3 lithostratigraphic units: sub-evaporitic (onshore-to-nearshore), evaporitic, and supra-evaporitic (offshore-to-estuarine). The upper unit includes a siliciclastic series (Upper Badenian–Sarmatian), which constitutes the main segment of the succession. It displays an asymmetric, shallowing-up trend, expressed by the following sequence: hemipelagic-turbiditic-deltaic-low-energy nearshore-to-estuarine facies associations. Sediment accummulation in the basin has been significantly overprinted by higher-frequency cyclicity and encloses several genetic stratigraphic sequences bounded by MFS surfaces. An early phase of the basin development was characterised by high-rate subsidence and slow-rate sedimentation (hemipelagic facies). The turbiditic facies association identified within the Sieniawa–Rudka area resulted from southward progradation of a submarine fan/prodeltaic depositional system, mainly fed from the northern and north–western continental margins of the basin. An overall SE–ward palaeoslope inclination controlled the main phase of the deltaic progradation, which had gradually replaced the turbiditic systems. The late deltaic phase was characterised by ENE palaeotransport directions. The final phase of the basin filling took place in shallow-water, low-energy, nearshore-to-estuarine environments. In the early stage of the basin development, a complex system of NW–SE elongated basement pop-ups and flower structures in the Miocene succession were produced by reactivation and inversion of Mesozoic basement faults. The growth of these positive structures modified local subsidence patterns and affected the organisation of depositional systems of the siliciclastic series. A narrow elevation of the RyszkowaWola High (RWH) gradually grew above one of the pop-up structures. Complex structural-stratigraphic hydrocarbon traps developed along the RWH, due to interaction between the growth of local faults and the development of the successive depositional systems. Tidally-modified delta-top and estuarine facies are the most common hydrocarbon hosts within individual sequences of the „deltaic” segment of the succession..

Opis:

The radiolarian biostratigraphy of the Middle–Upper Jurassic pelagic siliceous sediments (Czajakowa Radiolarite Formation) in the Niedzica succession of the Pieniny Klippen Belt (Carpathians) is interpreted in terms of their age in a stratotype section, and facies equivalents in other tectonic-facies units of this region. The siliceous sediments are represented by radiolarian cherts and silicified limestones which are underlain and overlain by red nodular limestones, equivalents of the Rosso Ammonitico facies. The radiolarian association includes thirty-seven taxa belonging to twenty one genera which represent the Northern Tethyan Palaeogeographic Province. Key radiolarians recorded provide a means of correlation with zonation schemes based on Unitary Associations defined for the Jurassic Tethyan sediments. The age of the Czajakowa Radiolarite Formation in the stratotype section is determined as U.A.Z.9 to U.A.Z.11 corresponding to middle Oxfordian up to Kimmeridgian. Comparison of radiolarian biozones from the stratotype section with other facial equivalent sections in the Pieniny Klippen Belt reveals a significant diachronism for both the lower and the upper limits of the Jurassic pelagic siliceous facies.

Opis:

Badania biostratygraficzne i litologiczne wykazały, że odwiercone osady interglacjału eemskiego powstały w jeziorze przepływowym występującym w dolinie rzecznej. Przeanalizowana fauna mięczaków ma znaczenie ponadregionalne i zawiera wiele gatunków charakterystycznych dla interglacjalnych warunków rzeczno-jeziornych. Na korelację piasków z interglacjałem eemskim wskazuje obecność gatunku Theodoxus fluviatilis. Stwierdzono obecność Marstoniopsis scholzi, który dotychczas nie był znany z osadów plejstoceńskich w Niemczech. Mało zróżnicowane spektrum pyłkowe dowodzi szybkiej sedymentacji w interglacjale eemskim podczas 4. i na początku 5. poziomu pyłkowego (por. Erd, 1973). Zwiększająca się zawartość amfibolu w osadach wskazuje na wietrzenie w pierwszej części interglacjału. Otaczająca wysoczyzna polodowcowa jest pokryta jednym pokładem gliny lodowcowej (faza meklemburska, qW3), która w dolnym odcinku doliny Peene bezpośrednio przykrywa eemskie osady rzeczne. Glina lodowcowa młodszego stadiału zlodowacenia Soławy (Warthian, qS2) podściela eemskie piaski rzeczne, natomiast niżej występująca glina lodowcowa została zakwalifikowana do starszego stadiału zlodowacenia Soławy (Drenthian, qS1). Eemskie osady rzeczne współczesnego dolnego odcinka doliny Peene wskazują na istnienie doliny rzecznej starszej od ostatniego zlodowacenia.

Opis:

An accumulation of glacial sediments is located near Písečná village in the depression between the Sokol Ridge and Zlaté Hory Highlands NNE of Jeseník town (Eastern Sudetes). The accumulation lies at the lateral side of the mountain valley of the Bělá River and fills a preglacial palaeovalley of this river. Research combining facies analysis of outcrops, ground penetrating radar survey, interpretation drilling survey, and modelling of the preglacial relief was undertaken at the site. According to the results obtained, the upper part of the sedimentary accumulation represents a coarse-grained terminoglacial glaciofluvial delta of the Gilbert type. The development of the accumulation has dominantly been driven by the preglacial morphology. Facies typical for foresets of coarse-grained deltas represented mainly by high-density flows, cohesionless debris flows, debris falls and less common low-density flows were found in the outcrops. The delta near Písečná prograded into a lake dammed by the ice-sheet front in the north. The lake was bounded by the slopes of Sokol Ridge, Zlaté Hory Highlands and Góry Parkowe on other sides. The lake level reached an altitude of up to 430 m a.s.l., as the coarse-grained delta plain base lies at this level.

Opis:

The main goal of this paper is to present the sedimentological and geochemical character of Krosno Beds from the Gorlice fold and the Stróże Thrust Sheet. Based on field work, two measured sections were made: western Stróże with true thickness of 300 m and eastern Lipinki with true thickness of 227 m. Within them, six sedimentary facies described in the Gorlice profile were identified and three newly recognized facies were distinguished. These facies have been interpreted in the framework of depositional mechanisms. Sedimentary structures were identified and described, including those important for reconstruct the sedimentation environment: hummocky-cross stratification (HCS) and trough cross stratification. Another element of the analysis is compilation of the measured field sections and their correlation with well logs from the Gorlice-12 and L-OU1 wells. The correlation enabled to show similarities of lithological development within the Gorlice fold and differences in relation to the Stróże Thrust Sheet profile. Eight samples of mudstone (Stróże profile 3 samples: S5–S7, Lipinki profile 5 samples: L3–L8) were collected and subjected to geochemical biomarkers analysis. The aim of the biomarkers study was to specify the character of the sedimentation environment and to confirm the biological/bacterial origin of compounds from the aryl isoprenoids group. Fifteen samples of bitumen extracts derived from two sections: Stróże in the Biała riverbed in the western part and Lipinka in the Libuszanka stream bed in the eastern part were selected for sample collection and testing. Aryl isoprenoids (short and medium chain) and higher diaryl isoprenoids have been identified. In addition, higher aromatic C40 carotenoids have been identified such as: isorenieratane, β-paleorenieratane, β-isorenieratane, β-renierapurpurane, chlorobactane and okenane. These are considered as a further evidence of the bacterial origin of aryl isoprenoids. The indices specifying the sedimentation environment were calculated: AIR, and isorenieratan/phenanthrene index. Samples were tested for: the character of the sedimentary environment, including photic zone anoxia (PZA) and its duration, depth of chemocline and bacterial activity during sedimentation. The results of the samples analysis used in this work were compared with the archival results of samples analysis (the Gorlice fold area).

Opis:

Well-developed N-S trending esker, described in literature as the Gostynin esker, consists of parallel ridges associated witch a tunnel valey flanked by the Vistulian (Weichselian) till plain. The sedimentary succession of one of the ridges is known in the Osada site. Complexity of the esker internal structure is expressed by 4 sedimentary units of different environments. The lowest, coarsegravelly (O1), developed by infilling a subglacial tunnel. The following one, making the main part of the esker ridge, is a sandy unit (O2) deposited in an ice-walled open channel. Locally, the deposits show normal synsedimentary faults. The O3 unit of fine-grained sediments was laid in a stagnant water. The succession is topped by a thin discontinous layer of flow till (O4). Sedimentation took place when the ice-sheet changed its dynamics from active to stagnant.
