Opis:

In the early Kimmeridgian (hypselocyclum Zone) tidal flat carbonate deposits cropping out in the large Wierzbica quarry at northern slope of the Holy Cross Mountains (20 km south of the town of Radom), characteristic Pteraichnus sp. tracks have been found. These tracks are assigned to pterosaurs and represent the first pterosaur ichnites found in Poland. Seven specimens of pterosaur tracks (pes and manus prints) are described, although no trackway can be observed. The manual prints are asymmetric, digitigrade and tridactyl. The pedal prints are elongate, symmetrical, plantigrade and functional-tetradactyl. Presence of pterosaur tracks point to subaerial conditions and supports the view that the Late Jurassic land, situated in Ukraine and Eastern Poland, temporarily extended to the northern part of the Holy Cross Mountains area.

Opis:

Upper Jurassic and Lower Cretaceous deposits of the Crimea Peninsula are rich in microfossils frequently used for stratigraphic interpretations. In case of foraminifera, the research has been carried predomi- nantly on assemblages obtained by washing the rock samples. The present paper is based on investigations of thin sections from the more indurated sediments that seldom were objects of study. Its goal was to obtain additional information on age and environment of sediments studied. Over 250 thin sections from 16 surface outcrops yielded abundant foraminifera from which over fourty are described herein. Many foraminiferal species (e.g., Labirynthina mirabilis, Parurgonina caelinensis, Neokilianina rahonensis, Amijella amiji, Anchispirocyclina lusitanica) are stratigraphically significant and known from the Kimmeridgian-Tithonian of the Mediterranean Tethys. The Early Cretaceous fauna is represented by Protopeneroplis ultragranulata, Everticyclammina kelleri, Nautiloculina bronnimanni, Monsalevia salevensis, and Mayncina bulgarica. Generally, the investigated fauna is typical for paleoenvironment of the carbonate platform. Older (Kimmeridgian-Tithonian) assemblages represent the inner, and younger (Berriasian) outer parts of the platform. Palaeogeographic distribution of many species described from the studied area indicates their affiliation with cosmopolitan biota known from the north Tethyan shelf. Additionally, few calcareous cysts of Dinoflagellata have been identified and described.

Opis:

A development project of the Zalew Balaton area is being presently carried out. One of the project assumptions is to create a geological path across the object. However, detailed data about the geological structure of this place is not available. For this reason, the author has researched and updated the information about the rocks occurring in the walls of the old quarry. Primarily, terrain (textural and structural analysis, layers strike and dip measurements, geological boundaries delimitation) and laboratory analysis (X-Ray Powder Diffraction, microscopic rock samples analysis) were conducted. Collected data was afterwards compared with available literature. Within the steep slopes of excavation, strong-karsted, faulted Upper Jurassic (Oxfordian) carbonate sediments were revealed. These are massive, platy and crumpled limestone. These rocks could be deposited in changing conditions of sedimentation, when calm carbonate sedimentation was disturbed by underwater gravity flows, as demonstrated by their detrital character. One of the karst funnel on the northern slope was filled with Oligocene sand. As a result, groundwater fluctuations created a sarsen structure, popularly called the “Wielbłąd”. In relation to the planned geological path across the Zalew Balaton area, previous knowledge should be supplemented with new data, respectively processed and included on information panes, located within object. Plans of the path should pay attention to potential geotouristic safety, as well as to the geological values of the protected object, during its future modernization.

The foraminifera-based biostratigraphy of the Middle and Upper Jurassic of the Polish Lowlands was re-evaluated. Biostratigraphic charts providing ranges of the most important foraminiferal taxa characteristic of individual Jurassic stages are presented in relation to the currently used ammonite-based standard stratigraphic divisions. The study contains the new research on the foraminifera fauna and includes earlier results available in published and archival reports. In the Oxfordian and Lower Kimmeridgian deposits, various foraminiferal assemblages were distinguished with reference to the lithofacies in the individual parts of the Polish Basin and varying influences of the palaeogeographical provinces. Additionally, the foraminiferal zones in the Oxfordian and Lower Kimmeridgian deposits of southeastern Poland are distinguished based on detail study of foraminifers.

Opis:

The source of clastic material supplied to the epicontinental sea during the Middle and Late Jurassic in the Pomeranian Segment of the northern part of the Mid-Polish Trough is analysed, using deposits from the Rzeczyn PIG-1 borehole that represent the Łyna, Chociwel, Brda, Pałuki, Kcynia and Rogoźno formations. Heavy mineral analysis, including weathering indices (ZTR, GZI, RZI and Q) and standardised scores for each mineral species, shows that each formation is characterized by a different heavy minerals association. In each association, transparent minerals include both ultrastable minerals (zircon, tourmaline and rutile), occurring in various proportions, and unstable minerals. This indicates that deposits subject to earlier multiple reworking were eroded from the surrounding landmasses. Most probably these deposits represented Triassic rocks, although fresh weathering covers were also eroded. The main direction of clastic material supply was from the N and NW, and to a lesser degree from the NE. The main reasons for changes in the source areas were probably sea level oscillations, while during regressions, exposed parts of the seabed became source areas of clastic material. Conversely, during transgressions, parts of the seabed became cut off from the supply of clastic material from eroded landmasses.

Opis:

The Upper Jurassic strata of the Krížna Unit in the Tatra Mts. comprises pelagic, fine-grained and well-oxygenated deposits. They are represented by red radiolarites and radiolarian limestones (Czajakowa Radiolarites Formation), red nodular limestones (Czorsztyn Limestones Formation) and wavy, platy or nodular light grey and reddish limestones and marlstones (Jasenina Formation). These deposits are mainly wackestones characterized by a succession of the following microfacies: radiolarian, filament-Saccocoma, Saccocoma and Globochaete–Saccocoma. The section comprises four calcareous dinoflagellate zones, i.e. the Late Kimmeridgian Moluccana Zone, and the Early Tithonian Borzai, Pulla and Malmica zones. In the uppermost part of the studied section, the Early Tithonian Dobeni Subzone of the Chitinoidella Zone has been identified. Using these biostratigraphic data, the sedimentation rate for the Late Kimmeridgian (Borzai Zone) and Early Tithonian (Dobeni Subzone of the Chitinoidella Zone) interval is estimated as 3.7 m/my. This is in accordance with the general trend of increasing sedimentation rate through the Tithonian and Berriasian. The increased supply of clastic material in the Jasenina Formation may have been caused by climate changes and continental weathering. The sedimentation was controlled mainly by eustatic changes and fluctuations in ACD and CCD levels.

Opis:

Upper Jurassic limestones exposed in the Będkowska Valley form an extensive complex of carbonate buildups of microbolite-sponge and microbolite-Tubiphytes reef-like bioherms, in which the main rock-building material are packstone and grainstone bound by microbolite structures. Horizontal discontinuity surfaces locally found in massive limestones are of sedimentary origin and are related to sediment gravity flows from the higher parts of the buildups. Two basic morphological types of carbonate buildups are distinguished in the vertical sequence of studied sediments: (i) one or a couple of large buildups forming a continuous biolitite cover with one type of sediment prevailing over a wide area in the lower part and passing upwards to (ii) numerous small buildups separated by depressions filled with packstone and grainstone formed from erosion of the buildups. The smaller, younger buildups were subject to early cementation which led to formation of extensive constructions.
Górnojurajskie wapienie Doliny Będkowskiej tworzą rozległy kompleks budowli węglanowych typu bioherm mikrobolitowo-gąbkowych i mikrobolitowo-Tubiphytesowych bioherm rafopodobnych, w których podstawową rolę skałotwórczą odgrywają ziarnity wiązane przez struktury mikrobolitowe. Poziome powierzchnie nieciągłości obserwowane niekiedy w wapieniach masywnych posiadają genezę sedymentacyjną związaną z drobnodetrytycznymi spływami z wyższych partii budowli. W badanych osadach można wydzielić dwa podstawowe typy morfologiczne budowli: (i) rozwinięte jako jedna lub kilka dużych budowli tworzących zwartą pokrywę biolitytową charakteryzującą się szerokim rozprzestrzenieniem jednego typu sedymentacji, (ii) oraz liczne ale niewielkie budowle, między którymi, w nieckach, osadzały się ziarnity pochodzące z erozji tych budowli. Budowle te wraz z otaczającymi je ziarnitami uległy wczesnej cementacji tworząc większe, złożone konstrukcje.

Abundant well−preserved salamander fossils have recently been recovered from localities across northeastern China. Pangerpeton sinensis gen. et sp. nov. is represented by a nearly complete skeletal impression of a postmetamorphosed salamander from the Late Jurassic/Early Cretaceous locality of Wubaiding, Liaoning Province. It is characterised by a short wide skull and only 14 presacral vertebrae. Associated soft tissue impressions suggest a warty skin and a broad body outline. Phylogenetic analysis indicates a basal position within Caudata, either just within or just outside crown−group Urodela.

Opis:

Oxygen and carbon isotope ratios of well-preserved calcitic bivalves from the Lower-lowermost Upper Kimmeridgian of Central Poland (SW margin of the Holy Cross Mountains) have been studied to reconstruct palaeoenvironmental conditions and variations in ancient water chemistry. Low and scattered δ18O and δ13C values of bivalve shells from shallow carbonate deposits of the Hypselocyclum and the Hypselocyclum-Divisum zone boundary (-3.5 to -1.5, and 2.6 to 4.0‰, respectively) are a result of salinity changes, and local variations in the composition of dissolved inorganic carbon (DIC) in conditions of restricted water circulation. A slight increase in bivalve δ13C values and more densely clustering of δ18O values is observed after the marine transgression at the Divisum-Mutabilis zone boundary. A global decrease of δ13C values of marine carbonates is partly recorded in Lower-lowermost Upper Kimmeridgian bulk carbonates from central Poland (from the Radomsko Elevation and the Wieluń Upland). Local negative shifts and the data scatter are, however, observed in rocks deposited in a very shallow environment of carbonate platforms during the Platynota and Hypselocyclum chrons. This interval corresponds to the uppermost part of the lowstand systems track of a major regressive trend, which had started already in the Late Oxfordian.

Opis:

The Oxfordian ammonite group Passendorferiinae (known as "Mediterranean perisphinctids") forms a group of perisphinctids characterized by strongly evolute serpenticone coiling and subcircular to subquadrate whorl section, and forms a lateral divergent branch of the main stem Perisphinctidae. They originated probably from Late Callovian Grossouvriinae (Alligaticeras) and spread mainly in the Mediterranean (Tethyan) Province along the southern margin of Tethys, occasionally reaching the outer areas of epicontinental platforms. Their particular morphological features make them somewhat homoeomorphic with Tethyan Kimmeridgian Nebrodites. The phyletic link might be represented by the genus Geyssantia Meléndez, known from the Late Oxfordian Planula Chronozone. Separate biogeographic distribution in relation to the Perisphinctinae might reflect a progressive differentiation of western Tethyan faunas at the Callovian-Oxfordian boundary and at the onset of the Middle Oxfordian Transversarium Chronozone. Their rapid evolution gives them a biostratigraphic value similar to that of the Perisphinctinae. At the turn of the Middle-Late Oxfordian they gave rise to early Ataxioceratinae (Orthosphinctes), which replaced the Perisphinctinae in epicontinental areas, and colonised the marginal epicontinental blocks of northern Tethys. The taxonomy of this group is based upon the recognition of sexual dimorphism, using a single generic and specific name for both (M) and (m), and hence rejecting the use of former subgeneric ames for both dimorphs. A new species within this line: Passendorferia nodicostata sp. nov. from the Plicatilis Biozone (Paturattensis Subbiozone) is defined and described for the first time.

Opis:

The present study summarizes the data on the continuous stratigraphic sequence of foraminiferal assemblages from the Volgian deposits of the south-east of Western Siberia. Microfaunal analyses of 650 core samples from 18 boreholes of Volgian deposits were performed. Eighty two foraminiferal species, identified from the samples, were combined into the Volgian assemblages. On the basis of these assemblages, four biostratigraphic units were established in the range of foraminiferal zones and foraminiferal beds with characteristic species. These biostratigraphic units correspond to the upper part of the Kimmeridgian/ lower part of the Volgian, the Middle Volgian (lowermost and uppermost beds), and the Upper Volgian. A detailed biostratigraphic analysis of the Volgian beds was carried out, which enabled a correlation scheme to be developed for major regions of Russia. West-Siberian foraminiferal assemblages were correlated with those of Europe and North America within the Panboreal Superrealm. The species composition of foraminiferal assemblages was analyzed, and correlatable species ere established. This provided an opportunity to correlate coeval strata from Western Siberia, East European (Russian) Platform, northern territories of Siberia and Arctic Islands, Canada, Spitsbergen and England. The possibility was established for correlating Volgian-Tithonian deposits of the Panboreal and Tethys-Panthalassa Superrealms through the Dnieper-Donets Basin where faunas of both southern and Boreal-Arctic types are met.

Opis:

The Upper Jurassic limestones in the vicinity of Cracow underwent extensive dedolomitization process. Petrographic and cathodoluminescent analyses of carbonates in four test areas confirm the dedolomitization as have been developed with various intensity. The alteration of dolomite into calcite occurs as centripetal and centrifugal dedolomitization. Both processes lead finally to a complete disintegration of the dolomite crystals; calcite pseudomorphs after dolorhombs are the end products. These calcite pseudomorphs are abundant in limestones of St. Anna Mt. and in the Kostrze quarry, but are scarce in the Twardowski Cliffs area and in the outcrop of Księża Mt., which indicates a less advanced and slower dedolomitization process in the latter two areas. Most probably the initiation of dedolomitization started from the moment when a carbonate bank emerged from the sea water (Vierek, 2003); temperature of mixing fluids decreased considerably, whereas Ca 2+/Mg+- ratio in the same fluids increased.

Opis:

A new genus and species of Tritylodontidae, Yuanotherium minor, is described and compared with other known tritylodontids. The new taxon is represented by a partially preserved upper jaw with three postcanines, collected from the upper part of the Shishugou Formation (Oxfordian, Late Jurassic) in the Wucaiwan area of the Junggar Basin, northwestern Xinjiang, China. Like other tritylodontids its maxillary teeth have three rows of blade−like trenchant cusps separated by deep furrows. The new species differs from other tritylodontids mainly in having posteriormost two cusps of the median row on upper postcanines closely placed. The new tritylodontid may have been omnivorous rather than herbivorous, as previously suggested for tritylodontids in general.

Opis:

The presented paper contains a detailed description of four species of the genus Craniscus DalI, 1871, found in the Upper Oxfordian of Bielawy and Wapienno quarries, Kujawy area. Three of them: Craniscus bipartitus (Munster, 1837), Craniscus antiquior (Jelly, 1843) and Craniscus corallinus (Quenstedt, 1852) have already been described from Poland, the fourth, however - Craniscus tripartitus (Munster, 1840), had only been known from the Lower Oxfordian of North Bavaria. The Craniscus specimens come from slope deposits of sponge-microbialitic bioherm. This is indicated by the fact that almost all specimens are dorsal valves, separated posthumously from ventral valves. The condition of some specimens and the rock lithology suggests, that the deposition was very violent in some cases and brachiopods were buried alive. The studied material is relatively well-preserved, which alIowes an accurate reading of the location of muscle scal's.

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:

The Callovian and Upper Jurassic strata in the Nida Trough are similar to those from SW margin of Holy Cross Mountains, so the same lithostratigraphic pattern may be applied. Three facies zones are distinguished: NW, central and SE. Black deposits of the Middle Jurassic are covered by the Sandy Limestones and Marls (lower Callovian–Bukowskii Subz. Cordatum Z.). Locally, these strata are separated by the Calcareous Sandstones (uppermost Bathonian–lower Callovian). The Marly Limestones and Marls represent Bukowskii Subz. Cordatum Z.- Plicatilis Z. The Morawica Limestones represent Plicatilis Z.–Bimammatum Z. The Siedlce Limestones (facies: pelitic, pelitic-sponge, pelitic-coral) reach the Platynota Z. in central andNWpart and the top of Hypselocyclum Z. in a narrow zone in SE part of Nida Trough. The Chalky Limestones (facies: pelitic, biostromal) are equivalents of the uppermost Siedlce Limestones in the centre of the Nida Trough. Beyond this narrow zone in the SE part of the Nida Trough, the Lowermost Marly Horizon (Platynota Z.) and deposits of shallow water carbonate platform (Platynota Z.–Hypselocyclum Z.), Lower & Upper Oolites, Banded Limestones, Oolite-Platy Member, Platy Detrital Limestones, Platy Limestones and Underlying Shales are distinguished. The uppermost part of the incomplete section (Divisum Z. and Mutabilis Z.) is represented by the Skorków Lumachelles and Upper Platy Limestones in the entire Nida Trough while the Staniewice Lumachelles occur in its SE part. The knowledge of the Middle– Upper Jurassic deposits of the Nida Trough is important for palaeogeographical reconstructions of the whole Southern Poland, as the Nida Trough links other regions where the Jurassic deposits are well recognized in numerous outcrops and borehole sections.

Opis:

The shell of the coleoid cephalopod mollusc Kostromateuthis roemeri gen. et sp. n. from the lower Kimmeridgian of Central Russia consists of the slowly expanding orthoconic phragmocone and aragonitic sheath with a rugged surface, a weakly developed post-alveolar part and a long, strong, probably dorsal groove. The sheath lacks concentric structure common for belemnoid rostra. It is formed by spherulites consisting of the needle-like crystallites, and is characterized by strong porosity and high content of originally organic matter. Each spherulite has a porous central part, a solid periphery and an organic cover. Tubular structures with a wall formed by the needle-like crystallites are present in the sheath. For comparison the shell ultrastructure in Recent Spirula and Sepia, as well as in the Eocene Belemnosis were studied with SEM. Based on gross morphology and sheath ultrastructure K. roemeri is tentatively assigned to Spirulida and a monotypic family Kostromateuthidae nov. is erected for it. The Mesozoic evolution of spirulids is discussed.

Opis:

This paper highlights the application of shallow non-invasive geophysics (electrical resistivity tomography) supported by sedimentological analysis applied to the investigation, description and interpretation of Upper Jurassic limestones exposed in the abandoned quarry near the village of Tomaszowice (Kraków Upland, southern Poland). Within this site, on the northern margin of the Krzeszowice Graben, a facies diversity of Upper Jurassic limestones can be observed. Field exposures were analysed to broadly characterize these Upper Jurassic limestones in terms of facies and microfacies development. Three facies types, including pelitic limestones, bedded limestones and carbonate gravity-flow deposits, composed of numerous microfacies, have been distinguished. ERT study using a dipole-dipole array has been carried out, along 5 parallel 110 m long profiles and along a perpendicular 110 m long profile, north of the Tomaszowice Quarry wall. The use of ERT in combination with the geological data allowed characterization and description of the geology at the research site as well as the determination of the lithological composition and internal architecture of the subsurface. Furthermore, the ERT interpretation results indicated the presence of a series of a secondary faults closely linked with the Krzeszowice Graben. The distribution of the gravity-flow deposits reflects the fault zone pattern of the graben and Late Jurassic fault activity.

Opis:

The system of huge organic buildups (sponge-microbial bioherms and coral reefs) has recently been mapped in the Carpathian foreland, S Poland, using high-quality petroleum seismic and well data interpreted using original, newly developed techniques. The sponge-microbial bioherms were formed during the Oxfordian time and the flat and mound-shaped coral reefs replaced them during the Late Oxfordian through Tithonian time. Both the bio-herms and reefs reflect the system of synsedimentary active extensional-transtensional blocks of the basement that controlled sea bottom highs which were likely colonized by the buildups constructors. It is possible to identify two systems of such faults: NW-SE oriented one and, less visible, W-E oriented one. The Late Jurassic organic buildups form excellent reservoirs for hydrocarbon accumulations. Effective seal for the traps is provided by the Upper Cretaceous (Senonian) marls. Late Cretaceous inversion resulted in reverse reactivation of main basement fault zones. During the Miocene, Carpathian thrusting-related flexural extension basement fault zones have been again reactivated in transtensional regime, which enhanced hydrocarbon prospectivity of selected areas due to juxtaposition of source and reservoir rocks. Miocene foredeep evaporates provide additional, very effective seal.

Opis:

The non-cidaroid echinoids (subclass Euechinoidea Bronn, 1860) from the Oxfordian epicontinental sequence of Poland (Polish Jura, Holy Cross Mountains, Mid-Polish Anticlinorium) are assigned to the genera Hemipedina Wright, 1855, Hemicidaris L. Agassiz, 1838, Hemitiaris Pomel, 1883, Pseudocidaris Étallon, 1859, Stomechinus Desor, 1856, Eucosmus L. Agassiz in Agassiz and Desor, 1846, Glypticus L. Agassiz, 1840, Pleurodiadema de Loriol, 1870, Diplopodia McCoy, 1848, Trochotiara Lambert, 1901, Desorella Cotteau, 1855, and Heterocidaris Cotteau, 1860, plus one acropeltid taxon, and one taxon left in open nomenclature. Within the genus Hemicidaris L. Agassiz, 1838, the relationship between Hemicidaris intermedia (Fleming, 1828), Hemicidaris crenularis L. Agassiz, 1839 [non Lamarck, nec Goldfuss] and Hemicidaris quenstedti Mérian, 1855, all with confused taxonomy, is discussed. Based on test structure, the genera Polydiadema Lambert, 1883, and Trochotiara Lambert, 1901, of the family Emiratiidae Ali, 1990, are proved to be separate; the common species mamillana of F.A. Roemer (1836) is a typical Trochotiara. An attention is paid to the morphology of the tiny, juvenile specimens, common in Eucosmus decoratus L. Agassiz in L. Agassiz and Desor, 1846, and in Pleurodiadema stutzi (Moesch, 1867).

Opis:

W artykule zaprezentowano wyniki analizy sejsmicznej i otworowej dla utworów jury górnej z rejonu usytuowanego na południe i południowy wschód od Tarnowa, której celem było określenie potencjału geotermalnego tego obszaru. Przeprowadzona analiza geologiczno-złożowa wykazała, że skały węglanowe górnej jury są dobrym kolektorem wód geotermalnych, a najbardziej perspektywiczne do uzyskania większych wydajności są strefy uskokowo-szczelinowe oraz strefy pogrążonego paleokrasu. Świadczą o tym opróbowania przeprowadzone w otworach wiertniczych w interwale skał górnojurajskich, które wykazały przypływy wód termalnych o wydajnościach do 30 m3 /h i temperaturze rzędu 50–80°C. Duża część z tych opróbowań związana jest bądź to ze strefami spękań i uskoków, bądź też z przypowierzchniową strefą rozwoju paleokrasu. Wspomniane utwory górnej jury zalegają w obszarze badań na głębokości od 1600 m do ponad 3000 m p.p.m. W ich nadkładzie występują węglanowe utwory kredy górnej, klastyczne utwory miocenu (autochtonicznego i jednostki zgłobickiej) oraz utwory jednostek tektonicznych Karpat. Zakres przeprowadzonych badań pozwolił na rozpoznanie budowy geologicznej oraz warunków złożowych analizowanego rejonu. Było to podstawą do wytypowania obszaru perspektywicznego, zlokalizowanego we wschodniej części obszaru badań, w obrębie którego można spodziewać się wyższych temperatur oraz możliwości uzyskania większych wydajności wód termalnych, koniecznych do zasilania obiektów energetycznych, ciepłowniczych czy też rekreacyjnych. W rejonie tym na podstawie danych sejsmicznych wyinterpretowano obecność skomplikowanego systemu uskoków, w większości o przebiegu z NW na SE. Dla wytypowanego obszaru perspektywicznego przedstawiono szczegółową charakterystykę parametrów złożowych, istotnych w kontekście poszukiwania i eksploatacji wód geotermalnych.
The article presents the results of a seismic and well analysis conducted for the Upper Jurassic formations in the area south and southeast of Tarnów, aimed at determining the geothermal potential of this area. A geological and reservoir analysis has shown that the Upper Jurassic carbonate rocks are a good collector of geothermal water, and the fault and fracture zones as well as the buried paleokarst zones are the most promising for higher yields. Tests conducted in wells in the interval of the Upper Jurassic rocks, showed thermal water flows of up to 30 m3 /h and temperatures in the range of 50–80°C. A large number of these tests are either associated with zones of faults and fractures, or with the near-surface paleokarst zone. These Upper Jurassic sediments occure in the study area at depths ranging from 1600 meters to more than 3000 meters below sea level. In their overburden are carbonate formations of the Upper Cretaceous, clastic sediments of the Miocene (autochthonous and the Zgłobice Unit) and formations of the tectonic units of the Carpathians. The scope of the study helped determine the geological structure and reservoir conditions of the analyzed region. This was fundamental to the selection of a prospective area, located in the eastern part of the study area, within which higher temperatures and the possibility of higher thermal water yields, necessary for power, heating or recreational facilities, can be expected. In this area, the presence of a complex fault system, mostly running NW-SE, was interpreted from seismic data. A detailed characterization of reservoir parameters relevant to geothermal water exploration and exploitation is presented for the selected prospective area.

Eleven new tracks from the Upper Jurassic of Portugal are described and attributed to the stegosaurian ichnogenus Deltapodus. One track exhibits exceptionally well−preserved impressions of skin on the plantar surface, showing the stegosaur foot to be covered by closely spaced skin tubercles of ca. 6 mm in size. The Deltapodus specimens from the Aalenian of England represent the oldest occurrence of stegosaurs and imply an earlier cladogenesis than is recognized in the body fossil record.

Opis:

The Upper Jurassic carbonates representing the microbial-sponge megafacies in the area of the Kraków-Częstochowa Upland (KCU) were locally silicified. In the reclaimed Lipówki Quarry, in Rudniki near Częstochowa (in the northern part of the Upland), macroscopically different silicification products were observed in blocks of Upper Jurassic limestones, deposited as mining waste. Two varieties were distinguished: (i) chert concretions representing the I silicification stage and (ii) light-brown, silicified limestones infilling the fractures in chert concretions or forming the cortices around the concretions or forming irregular bodies, all representing the II silicification stage. The diagnostic features are the following: (i) macroscopic development, (ii) the presence of moganite exclusively in chert concretions and (iii) significant differences in crystallinity index (CI) values, namely: 0.1–0.7 for chert concretions and 6.0–6.6 for silicified limestones. The formation of chert concretions was initiated as early as in unconsolidated sediment, whereas the II silicification stage followed the chemical compaction of the limestones. The results of geochemical analyses of the products of both silicification stages indicated that the probable source of silica were the low-temperature hydrothermal solutions. Two types of fractures were found in the chert concretions, generated during different tectonic events. The older, open fractures were formed during the extension of the Late Jurassic sedimentary basin, which formerly occupied the territory of the more recent KCU. These fractures were infilled with unconsolidated, fine-detrital carbonate sediment, in which the concretions were embedded and finally silicified in the II silicification stage. The younger, closed fractures, transversal to those filled by the products of II silicification stage, along which small displacements are evident, document the later tectonic deformations presumably related to Cenozoic faulting.

Opis:

Foraminifera, ammonites, and calcareous dinoflagellates were used for stratigraphy and, together with microfacies, for the assessment of the palaeoenvironmental conditions of the Upper Jurassic deposits in the central Alborz Zone of northern Iran. The Lar Formation (Lar Fm.) in the Polur section is of latest Oxfordian to early Kimmeridgian age. The ammonite Subnebrodites planula and the calcareous dinoflagellate Colomisphaera nagyi have been introduced as new biomarkers of the lower Kimmeridgian in the central Neo-Tethys. The distribution of calcareous dinoflagellates reflects possible dispersal routes along a narrow seaway between the western Neo-Tethys and the Alborz Zone in the central Neo-Tethys. The Terebella-Crescentiella associations of the Lar Fm. represent a low-energy setting under dysoxic conditions in the Central Neo-Tethys Ocean. The benthic foraminiferal assemblages in this formation show a high dominance of infaunal taxa and r-selected strategists. This assemblage is reminiscent of eutrophic conditions and low oxygen levels in the lower part of the Lar Fm. Good preservation of the hexactinellid sponges in the upper part of the Lar Fm. also indicates an oxygen-minimum zone. Three third-order depositional sequences can be distinguished in the study area based on six microfacies. Depositional sequence 1 (DS1) is composed mainly of argillaceous limestone and medium- to thick-bedded limestone, corresponding to an outer ramp-to-middle ramp environment. Depositional sequence 2 (DS2) comprises breccia limestone and thick-bedded limestone facies in its lower part and thin-bedded limestone to massive limestone in its upper part. The breccia limestone facies may be associated with subaerial exposure and reworking of previously deposited sediment during a relative sea level fall. The thin-bedded limestone to massive limestone of DS2 consists mainly of bioclastic mudstone to wackestone (outer ramp). These represent an deep-water outer homoclinal ramp facies. Depositional sequence 3 (DS3) consists mainly of massive limestone to thick-bedded limestone with a bioclastic peloidal microbial Crescentiella packstone (middle ramp). The relative stratigraphic positions of DSs1–3 and sequence boundaries in the uppermost Oxfordian to lower Kimmeridgian of the Polur area show a fair match to the upper Oxfordian to lower Kimmeridgian sequences (JOx7, JOx8, JKi1 and JKi2) on the global sea level curve.

Opis:

Three objects were studied within a project aimed at investigation of stones used in the Romanesque edifices in the vicinity of Kraków, and continued since 2019. These are the churches in Dziekanowice (21 km SE of Kraków) and in Czchów (58 km SE of Kraków), and a clergy house in Morawica (13 W of the Kraków city centre). The church in Dziekanowice is relatively completely and well preserved, while the only Romanesque remnants of the church in Czchów are those reused in the Gothic church. It is a clergy house in Morawica (a former castle), whose walls contain Romanesque fragments. Two former edifices are built of the Istebna sandstone (Upper Cretaceous-Paleogene), quarried from the local flysch bedrock. Fine-grained, grey-yellowish stone dominates. It is soft and easily workable due to argillaceous binder (matrix). The stone blocks are precisely shaped and well fitted. Romanesque remnants of the clergy house in Morawica are con- structed predominantly of limestone, also of local origin. Only a fragment of the NW wall is built of the Istebna sandstone. This fragment is probably a part of the butress supporting the NW wall. The study shows that stonemasons and builders of that time had good skills of selecting and applying proper stone blocks for particular purposes. Blocks used in load-bearing structures were exceptionally well shaped and fitted. On the other hand, those skills varied. The frieze from the Romanesque church in Czchów is rather primitive. The size of limestone blocks used in the clergy house in Morawica is strikingly similar to those of various Romanesque edifices in Kraków. It seems, therefore, that those blocks could have been quarried and shaped in quarries located in the city, where the masonry “industry” was well developed. Larger, irregular blocks, used as foundations and filler in the “opus emplectum” type walls were probably quarried on site. Moreover, stones used in more eminent edifices (churches, castles) were probably more carefully selected. The Morawica castle (clergy house) and many churches in Kraków were built of limestone blocks without cherts.

Opis:

A partial skeleton of a new sauropod dinosaur from the Upper Jurassic Morrison Formation (?Tithonian) of Montana is described. Suuwassea emilieae gen. et sp. nov. is diagnosed by numerous cranial, axial, and appendicular autapomorphies. The holotype consists of a premaxilla, partial maxilla, quadrate, braincase with partial skull roof, several partial and complete cranial and middle cervical, cranial dorsal, and caudal vertebrae, ribs, complete scapulocoracoid, humerus, partial tibia, complete fibula, calcaneus, and partial pes. It displays numerous synapomorphies of the Diplodocoidea, including characters of both the Diplodocidae (Apatosaurus + (Diplodocus + Barosaurus)) and Dicraeosauridae (Dicraeosaurus + Amargasaurus). Preliminary phylogenetic analysis indicates that Suuwassea is a diplodocoid more derived than rebbachisaurids but in a trichotomy with both the Diplodocidae and Dicraeosauridae. Suuwassea represents the first well−supported, North American, non−diplodocid representative of the Diplodocoidea and provides new insight into the origins of both the Diplodocidae and Dicraeosauridae.

Opis:

Migration and concentration of heavy metals in infiltration waters within unsaturated and saturated zones of a carbonate massif result from their mobility as well as anthropopression. The purpose of this project, carried out in 1995-2005, was to observe changes in the chemical composition of infiltration waters, especially Sr, Ba, Fe, Mn, and Zn concentration in precipitations, in soils and in caves within an unsaturated zone and a saturated zone situated in a carbonate massif. Field research was conducted in the Prądnik River’s drainage basin and at the Zakrzówek horst in Kraków. The chemical and mineralogical composition of limestone samples from 11 different quarries and natural exposures in the Kraków Upland were studied. The mineralogical research was conducted using the Roentgen diffraction method. The concentration of Sr, Ba, Fe, Mn and Zn in 700 samples from precipitation, caves and saturated zone waters was analysed. The determinations were made using mainly the ICP-AES Plasma 40 and ICP-MS Elan method. To assess the quality aspects of the migration of heavy metals, the results of the geochemical modelling were accounted for using the PHREEQC software. The hydrochemical research has shown distinct variability of concentrations of the analysed minor elements in different forms of precipitation (the highest concentrations being observed in sleet and the lowest in pure snowfall). In rainwater as well as in waters of the unsaturated and saturated zones, quantities of the five chemical elements appeared in the following decreasing order: Fe>Zn>Mn>Sr>Ba and Sr>Ba>Fe>Zn>Mn. The chemical composition of infiltration waters in the carbonate massif changes vertically. The fundamental trends in the waters of this area include an increase of Sr and Ba concentrations, a decrease of the concentration of Zn, and static concentrations of Fe and Mn.

Opis:

A relatively rich assemblage of starfish is recognised from the talus facies of an Upper Jurassic (lower Kimmeridgian) biohermal, sponge-cyanobacterial build-up from the Wapienno/Bielawy succession exposed in a salt-dome anticline in Kuyavia region, north-central Poland. The paper presents 8 taxa belonging to 4 genera (one new to science): Boxaster gen. nov., Noviaster Valette, 1929, Tylasteria Valette, 1929, Valettaster Lambert, 1914, and 4 families: Astropectinidae Gray, 1840, Goniasteridae Forbes, 1841, Sphaerasteridae Schöndorf, 1906 and Stauranderasteridae Spencer, 1913. Only a very few representatives of some of these taxa have formerly been reported from the Jurassic of Poland. Two species are new: Valettaster planus sp. nov. and Boxaster wapienensis gen. et sp. nov. The Jurassic starfish assemblage recognised from the Wapienno/Bielawy succession is interpreted as an offshore starfish fauna with the admixture of allochtonous shallow-water taxa. The lithology of the source deposits indicates their transport by storm agitation and/or mass movements. This fact strongly influenced the preservation state, all collected plates being disarticulated and most of them abraded.

Opis:

The paper presents a comparative analysis of a Lower Kimmeridgian layer with bored and encrusted hiatus concretions collected in three study areas, located in Central Poland. These studies demonstrate distinct similarities between the hiatus concretions in terms of their origin, development and stratigraphic position. The layer with its characteristic concretions seems to represent an important marker horizon for the Lower Kimmeridgian successions in Central Poland. The identification of this marker horizon in drill cores and exposures could be important for definition of the stratigraphic position of the sediments, which otherwise lack appropriate biostratigraphic information. The matrix of the concretions is composed of pelagic calciturbidites, which reflect flooding of the early Kimmeridgian platform. These sediments were lithified early and formed a hardground. The origin of the hiatus concretions probably is related to erosion of the hardground, followed by redeposition and several phases of exhumation and erosion, preceding final burial. The characteristic ecological successions, observed in the concretions, document an evolution from soft to firm and hard marine substrates, typical of hardgrounds and evidenced by various burrows, borings (Gastrochaenolites, Trypanites), and epizoans. Calciturbidite sedimentation, hardground erosion and redeposition of the hiatus concretions, known from deposits of the Platynota Zone in Central Poland, were associated with synsedimentary activity of the Holy Cross Fault, on the NE margin of the extensive, tectonic Małopolska Block.

Opis:

An isolated posterior cervical vertebra of a sauropod discovered at Phu Dan Ma (Kalasin Province, northeastern Thailand) is the first informative postcranial specimen from the Phu Kradung Formation, a Upper Jurassic to Lower Cretaceous continental unit. The vertebra is referred to the family Mamenchisauridae, otherwise mainly known from China. In addition, spatulate teeth from the same formation and a mid−dorsal vertebra from the Upper Jurassic Khlong Min Formation of southern Thailand are reassigned to this family. The occurrence of mamenchisaurids in the earliest Cretaceous of Thailand supports a hypothesis of geographical isolation of Central, Eastern, and Southeast Asia during the Late Jurassic. It also suggests that the main changes in their dinosaur assemblages occurred during the Early Cretaceous, rather than at the Jurassic–Cretaceous boundary.

Opis:

New biostratigraphical and carbon isotope data are presented for the Upper Jurassic limestones of the Raptawicka Turnia Limestone Formation (High Tatric unit, Western Tatra Mountains, Poland) from the Mały Giewont area. The Kimmeridgian, lower Tithonian and lower part of the upper Tithonian have been identified on the basis of calcareous dinocysts and calpionellids. Eight microfossil biozones are distinguished: acme Fibrata, acme Parvula, Moluccana, Borzai, Tithonica acme Pulla(?), Malmica, Chitinoidella and Crassicollaria (pars). The Kimmeridgian/Tithonian boundary is indicated at the top of the Borzai Zone 76 m above the base of the Raptawicka Turnia Limestone Formation. The microfossil stratigraphy suggests the late Early Kimmeridgian age (acme Parvula Zone) of the ammonites described by Passendorfer (1928). The taxon Taramelliceras ex gr. compsum found 14 m above those ammonites is Late Kimmeridgian in age. Seven microfacies types (MF) are identified in the Upper Jurassic limestones of the Mały Giewont area. The Bositra-Saccocomidae MF occurs across the Lower-Upper Kimmeridgian boundary. The planktonic and benthic foraminifera occur in the Upper Jurassic deposits of the Raptawicka Turnia Limestone Formation. The genera Lenticulina Lamarck and Spirillina Ehrenberg are common in the Kimmeridgian and Tithonian limestones. The palaeobathymetric evolution of the Kimmeridgian-Tithonian deposition recorded in the Mały Giewont sections reveals: the transgressive episode at the Lower/Upper Kimmeridgian boundary interval, the transgression peak during the Early Tithonian (Malmica Zone) and gradual shallowing of the High-Tatric swell in the Late Tithonian. Integrated isotope stratigraphy and biostratigraphy enabled correlation with the pelagic section of the Sub-Tatric succession in the Długa Valley section. The middle part of the Raptawicka Turnia Limestone Formation (Upper Kimmeridgian) might be correlated with the upper part of the Czajakowa Radiolarite Formation (red radiolarites) and Czorsztyn Formation in the Długa Valley section. The upper part of the Raptawicka Turnia Limestone Formation of Early Tithonian age corresponds mostly to the Jasenina Formation. The overall similarity of the δ13C decreasing values recorded in the Kimmeridgian–earliest Tithonian interval of the Mały Giewont (this study) and Długa Valley sections indicates that the generally shallow-water deposits of the Raptawicka Turnia Limestone Formation accumulated below the zone influenced by changes in the composition of marine water caused, for instance, by intense rainfalls.

Opis:

Two partial skeletons of allosaurid theropods belonging to an adult and a juvenile from the Upper Jurassic (Tithonian) Morrison Formation of McElmo Canyon in Montezuma County, southwestern Colorado, were discovered in 1953 by the late Joseph T. Gregory and David Techter. The adult specimen consists of several isolated cranial and postcranial skeletal elements that are exceptionally well-preserved and include the left premaxilla, maxilla, dentary, teeth, quadratojugal, two caudal vertebrae, pubic peduncle, ischium, proximal tibia, a nearly complete left foot, and several isolated teeth, whereas the juvenile specimen is represented by the distal portion of the right dentary and a fragmentary splenial. The specimens represent a new species of Allosaurus, here named Allosaurus lucasi, which differs from Allosaurus fragilis by having a relatively short premaxilla and robust quadratojugal with short jugal process and a short quadrate process of the quadratojugal that is at the same level as the rostral quadratojugal ramus. The presence of a new species of Allosaurus in the Tithonian of North America provides further evidence of the taxonomic and morphological diversity of the Allosauridae clade and their continuous evolutionary success, which extended to the Cretaceous.

Opis:

The ammonite succession in the stratigraphical interval from the Bifurcatus Zone, through the Hypselum Zone, up to the lower part of the Bimammatum Zone corresponding to a large part of the Submediterranean Upper Oxfordian is studied in several sections of the Polish Jura in central Poland. The sections have yielded numerous ammonites of Submediterranean–Mediterranean affinity, but also, some of Boreal and Subboreal character. The co-occurrence of ammonites of different bioprovinces makes possible the correlation between the different zonal schemes – especially between the Subboreal/Boreal zonations and the Submediterranean/Mediterranean zonation. The correlation shows that the boundary of the Pseudocordata and Baylei zones (Subboreal) and its equivalent – the boundary of the Rosenkrantzi and Bauhini zones (Boreal), currently proposed as the primary standard of the Oxfordian-Kimmeridgian boundary within its GSSP at Staffin Bay (Isle of Skye, Scotland), runs in the Submediterranean/Mediterranean Upper Oxfordian near the base of the Bimammatum Zone. This discovery removes the main obstacle against the formal recognition of the Staffin Bay section as representing the uniform base of the Kimmeridgian Stage in the World and its GSSP. The ammonite taxa recognized are commented on and/or described, and suggestions on their taxonomical and phylogenetical relations are given in the palaeontological part of the study. A new taxon is established: Microbiplices anglicus vieluniensis subsp. nov.

Opis:

The Buila-Vânturariţa Massif consists of massive Upper Jurassic reef limestones (Kimmeridgian–Tithonian) and Lower Cretaceous (Berriasian–Valanginian, and Barremian–?Lower Aptian) deposits. Besides corals and stromatoporoids, a wide range of micro-encrusters and microbialites has contributed to their development. In this study, the authors describe briefly and interpret the main facies associations and present the microfossil assemblages that are important for age determination. The distribution of facies associations, corroborated with the micropalaeontological content and early diagenetic features, indicate different depositional environments. The carbonate successions show the evolution of the Late Jurassic–Early Cretaceous depositional environments from slope and reef-front to internal-platform sedimentary settings, including peritidal environments in the lowermost Cretaceous. Early diagenesis, represented by synsedimentary cementation in the form of micritization (including cement crusts in the reef microframework), followed by dissolution, cementation and dolomitization in a meteoric regime, and void-filling late cementation during the burial stage.

Opis:

Przedstawiono wyniki badań utworów jury górnej w dwóch peźnordzeniowych profilach wierceń, które opracowano przy realizacji „Zintegrowanego programu płytkich wierceń badawczych dla rozwiązania istotnych problemów budowy geologicznej Polski”. Utwory jury górnej reprezentują megafację gąbkową. Profil otworu wiertniczego Trojanowice 2 charakteryzuje biohermalny obszar facjalny w obrębie całej przewierconej części profilu oksfordu (od oksfordu dolnego do najniższej części poziomu Bimammatum oksfordu górnego). Profil Cianowice 2 charakteryzuje basenowy obszar facjalny (miedzybiohermalny basen Korzkwi) w obrębie niemal kompletnego stratygraficznie oksfordu. Znaczne różnice reliefu dna zbiornika wykazane na podstawie precyzyjnej biostratygrafii predysponowały do różnego rodzaju ruchów masowych. Utwory reprezentujące efekty takich ruchów rozpoznano w wyższej części profilu Cianowice 2. Stwierdzono, że zróżnicowanie na dwa wymienione powyżej obszary facjalne rozpoczęło się z początkiem późnego keloweju. Określono gęstość mumii gąbkowych w biohermie otworu wiertniczego Trojanowice 2. Zmieniała się ona od kilku do 63 mumii na metr bieżący profilu. W liczącym 201 m profilu doliczono się 2199 „generacji” gąbek krzemionkowych. Dla tego samego profilu wiercenia obliczono skrócenie profilu wapieni biohermalnych w wyniku procesu rozpuszczania pod ciśnieniem (stylolityzacji wzdłuż płaszczyzn poziomych). Minimalne skrócenie, obliczane jako amplituda stylolitu, wyniosło średnio 11,6%.
We present the results of research in two Upper Jurassic drill core sections which were conducted with in the frames of “Integrated research program of shallow drillings to solve the major problems of geology of Poland”. The sections represent the Upper Jurassic sponge megafacies. The Trojanowice 2 drill core records the biohermal Oxfordian facies (from the Lower Oxfordian to the lowermost part of Bimammatum Zone of the Upper Oxfordian). The Cianowice 2 section is characterized by a facies typical of interbiohermal basins (Korzkiew Basin) and shows a nearly complete Oxfordian stratigraphic section. Significant differences of the sea bottom relief shown by the precise biostratigraphic method, evoked various types of mass movements. Rocks representing the effects of such movements have been recognized in the upper part of the Cianowice 2 drill core. The differences between the two regions mentioned above are evident from the beginning of the Late Callovian. We have determined the density of the sponge mummies in the Trojanowice 2 drill core. It varied from a few to 63 mummies per 1 metre of the section. In the 201-m long profile, a total of 2199 “generations” of siliceous sponges were found. In the same profile, we calculated the shortening of the limestone thickness as a result of pressure dissolution (along a horizontal plane). The minimal shortening, calculated as the stylolite amplitude, was averagely 11.6%.

Opis:

The Owadów-Brzezinki quarry is one of the most important paleontological sites in Poland, known from its exceptionally well-preserved Late Jurassic (Tithonian) fossils of marine and terrestrial biota, including horseshoe crabs and decapod crustaceans, rare ammonites, various insects and pterosaurs. This paper describes the discovery of new, well preserved reptile bones (ichthyosaurs, turtles and crocodylomorphs), which adds sigmficantly to our knowledge of these three gr°upü. The occurrence of large marine reptiles show open marine connections with the Sub- boreal-Boreal areas (both with Subboreal English seas and Boreal Arctic areas), and the Submediterranean Province (corresponding to the area of southern Germany).
