Opis:
The cave of Smocza Jama located in the centre of Kraków is developed in the Wawel Horst built of Upper Jurassic limestone and surrounded by grabens with Miocene clays. The cave is composed of two series: the old one has been known for ages and the new one was discovered when an artificial shaft was mined in 1974. The new series comprises small chambers separated by intervening thin walls while the old series consists of three connected together spatial chambers. The cave abounds in extensively developed solution cavities – cupolas and ceiling pockets. The internal fine-grained deposits, predominantly representing clay fraction are built of illite, mixed layer illite-smectite, kaolinite and iron oxides. They are probably the residuum after dissolution of Jurassic limestone. The cave originated in phreatic condition due to water input from below. The new series represents juvenile stage of cave evolution. The water rose through fissure-rifts located in chamber bottoms, circulated convectionally within particular chambers, finally led to bleaching of intervening walls, and hence to connection of the neighbouring chambers. The evolution of the old series is far more advanced. The rounded solution cavities imply that the cave was formed by water of elevated temperature. The lack of coarse-grained fluvial deposits, Pleistocene mammal remains and Palaeolithic artefacts prove that the cave was isolated since its inception till Holocene time. The cave originated due to artesian circulation, when the Wawel Horst was covered by imper- meable Miocene clays. A foreland basin with carbonate basement, filled with fine-grained molasse-type deposits seems to be particularly favourable for the development of artesian caves.

Large exposure near the brick-field in Halie represents one of the most complete loess sequences in the Ukrainian Car- sq pathian F orcland, which i I lustrates a progress of events covering a considerable part of the Middle Pleistocene and the whole Upper Pleistocene. The most important of these arc: the Luck soil corresponding to the soil from the Zbójno lnicrglacial in Polish profiles and Dornnitz Interglacial (1~0 stage 9) in West European profiles, bottom part of the Upper Pleistocene (Dnieper= Odranian = Saalian I) loesses, which arc extremely thick and stratigraphically divided into units of lower rank. and well developed soil complexes - Korshov and Horok hov. Investigations of the Korshov soil arc a basis to discuss at least two stages/phases ofpedogcncsis development during the last but one interglacial (Lublinian = Trcenian: 1~0 stage 7). The Horokhov paleosol is connected with the Ecmian Interglacial. The Dubno and Rovno soils occur within the poorly developed Vistulian loesses: the Rovno soil is a cultural layer.

Opis:
The studied corals have been collected from cores of boreholes located in the central part of the Polish Carpathian Foreland in the Dąbrowa Tarnowska–Szczucin area. The Jurassic complex in this area presents a continuous stratigraphic section from the Upper Callovian to Tithonian, locally passing to the Lower Cretaceous (Berriasian). Its thickness exceeds 1,100 m in this area. This complex is composed of marine, mainly shallow-water deposits. The corals occur within the upper part of the Upper Jurassic (Tithonian) deposits, almost entirely within the Swarzów Limestone Formation (= coral-algal limestone formation). This occurrence marks the northernmost extent of Tithonian shallow-water corals in Poland and one of the northernmost in Europe. 42 coral species (among them 14 in open nomenclature) were identified in deposits of this formation. They include two new species: Complexastrea magna and Complexastrea dabroviensis. All taxa, except one, belong to the order Scleractinia. The described assemblage displays a Late Jurassic character. The broader stratigraphic span is assigned to some species, which are quoted from the Middle Jurassic and some species lasted until the Early Cretaceous, Berriasian and/or Valanginian.

Opis:
The Kolodiiv section is situated in the central part of the East Carpathian Fore land, on the right bank of the Sivka River, the Carpathian tributary of the Dniester River. This paper summarizes investigations on the loess deposit succession representing the Late Pleistocene, which is subdivided by several interstadial palaeosols and is bracketed by the last interglacial soil/organic deposits and Holocene soil. The Kolodiiv loess-palaeosol sequence provides an excellent high-resolution terrestrial archive of changing climate during OIS 5-2 in the East Carpathian Fore land and forms the basis for a regional pedo- and loess stratigraphy. The stratigraphic scheme was constructed on the basis of palaeosol occurrence, lithological variation in the deposits, and also the results of TL dating and palaeomagnetic in vestigations. The exposure at Kolodiiv contains an archaeological site with Middle Palaeolithic materials. Four types of palaeopedological taxa have been distinguished within the loess deposit at Kolodiiv: an interglacial (Eemian) soil unit, which includes one or two soil-forming episodes; interstadial palaeosols, which include two weaker soil-forming episodes; thin interstadial two-horizonpalaeosols; monogenetic incipient palaeosols. Palaeosols from the first and second group form the Horohiv soil unit correlated with OIS 5. Palaeosols from the third and fourth group occur as different soil types within the Dubno 1 and 2 units, which correspond to OIS 3.

Opis:
A high-amplitude anomaly in seismic signal, i.e. a bright-spot, which is the main direct hydrocarbon indicator, may also occur due to interference between the reflected signals from the top and base of a thin bed (the tuning effect). In such settings the main problem is to distinguish amplitude anomalies associated with lithological changes or changes in gas saturation from anomalies originating from the tuning effect. We provide a method of interpreting the composite seismic signal produced by the interference between reflections. Such reflections occur along the top of the Cenomanian sandstone in the area of the Grobla–Rajsko–Rylowa 3-D seismic dataset (southern Poland). The non-standard method presented here is based on interpretation of seismic data which was rotated by 270°. The results of seismic modelling were used to develop criteria for interpretation of such data. These criteria are based on the difference between information carried by the peak-to-trough amplitude and that by the total amplitude of rotated seismic data. The difference was used to define the transfer function and to remove the high-amplitude anomalies caused by the constructive interference between the reflected signals from the top and bottom of the thinning stratum. The final outcome of the study was a map showing the seismic amplitude response at the top Cenomanian reflector unaffected by the tuning effect. The map shows the extent of the area where high-amplitude anomalies do not correspond with changes in thickness and petrophysical parameters within the top part of the Cenomanian. These anomalies are caused by a lateral increase in thickness of the Turonian and/or an increase in the velocity within the bottom part of the Senonian (Coniacian) strata. The map can be used to determine precisely the boundaries of the Rajsko and Rylowa gas reservoirs as well as to locate the potential extension of the reservoir zone to the east of the Rylowa 6 borehole.

Opis:
In the latest Precambrian and Early Cambrian, turbidity currents and cohesive flows transported pebbles, sand and mud into a deep water in south-east Poland, this sediment probably being sourced from Gondwana. Abundant detrital albite grains suggest volcanism during sedimentation. Pebbles in conglomerate interbeds are polymict and include rock fragments showing greenschist facies regional metamorphism in the source area. The Precambrian surface in the marginal part of the Carpathians lies at 2000-5000 m b.s.l., whereas farther south, around Kuźmina it reaches 7000 m. Still farther south (Krosno-Sanok-Baligród) geophysical evidence suggests it lies at about 17-20 km depth.

Carpathian Foreland
Peri-Tethys
Opis:
During the Early Cretaceous a central part of the Carpathian Foreland was situated in the Peri-Tethys area. That zone was located on the SW margin of the East European Craton and it was adjacent to the Tethys basins in the south. Impact of those both zoogeographic provinces (the Boreal Sea and the Tethys Ocean) is easily noticeable in assemblages of microfauna. Character of sedimentation in the Early Cretaceous basin of the Carpathian Foreland is connected mainly with changes of the sea-level as well as tectonic activity of this region. The stratigraphy and facies data are based on near two hundreds wells profiles. Detailed sedimentological profiles and photographic documentation of the Upper Jurassic and the Lower Cretaceous deposits from about 50 boreholes were done as well as micropalaeontological and microfacial studies of core samples. The presented work is an attempt of unification and formalization of lithostratigraphic units’ nomenclature. Two boreholes: Zagorzyce-7 andWiewiórka-4 were suggested as stratotype sections of distinguished formations. Jurassic–Cretaceous boundary is probably situated within limits of Ropczyce formation in this area. Three formations have been distinguished in the profile of Lower Cretaceous above Ropczyce formation: Zagorzyce limestone-marl formation (Berriasian age), Dębica marl and organodetritic limestone formation (Valanginian) andWiewiórka limestone formation (Late Valanginian-Hauterivian). The most marked erosion surface is recorded between Zagorzyce and Dębica formations. We suppose that hiatus including a large part of Lower Valanginian profile is connected with that erosion surface. It could be refered to a rapid fall of the sea-level in the Tethys Ocean, noticed inter alia in theWestern Carpathians and the Northern Calcareous Alps. The known existing thickness of the Lower Cretaceous sediments in the middle part of Carpathian Foreland (total of three formations: Zagorzyce fm., Dębica fm. andWiewiórka fm.) rises to 188 m in Zagorzyce-1 well.

Opis:
The main purpose of the article was to reconstruct the structural details of the Triassic and Palaeozoic formations of the central part of the Carpathian Foreland based on interpretation of new 3D seismic data. The interpretation included the analysis of seismic attributes, among them Time Gain, Relative acoustic impedance, First derivative, Dominant frequency and Instantaneous bandwidth were the most useful. Previous knowledge on the geological structure of the Palaeozoic complex in this area was derived mainly from the interpretation of 2D seismic sections, regional concepts and data from the only deep well drilled in the late 1950s and early 1960s. The results of the seismic image analysis show that the Jurassic sub-surface is composed of a number of tectonic blocks of various sizes, separated by dislocation zones. Most of them are tilted blocks which are the remnants of the Caledonian-Variscan tectonic system. Palaeozoic sediments with clearly arranged continuous seismic reflectors strongly contrast in the seismic image with the complex of anchimetamorphic rocks of the uppermost Ediacaran characterized by disarranged, homogeneous record. Clastic formations of the Lower Triassic fill primarily the deeper parts of the tectonic half-grabens. Based on the seismic image analysis, the complex is divided into two series: the lower one, with significantly lower amplitude values and noticeably lower continuity of seismic reflectors and the upper one with diversified dynamics and greater continuity of reflectors. The highest analyzed complex is the carbonate formation of Roetian and Muschelkalk, characterized by high amplitude values and high continuity of reflectors so that it can be easily identified on seismic sections. The analysis carried out with the use of seismic attributes allowed to determine the seismic characteristics of individual lithostratigraphic complexes of the Triassic and Palaeozoic formations and provided more detailed information on the geological structure of the research area.

Well-logging data, P and PS wavefields were used in the research. On the basis of the detailed analyses (i.e., seismic modeling, seismic inversion, AVO analysis) distribution of acoustic and elastic impedances, S-wave impedance, P and S-wave velocities and AVO product were calculated. Application of a geostatistical method with a use of obtained attributes and log data enabled estimation of porosity, clay content distributions and gas saturation along the profile.

Opis:
Stratygrafia sekwencji jest multikompontentowym narzędziem służącym do odwzorowywania architektury depozycyjnej, środowisk sedymentacji, litofacji i ich przestrzennego rozmieszczenia. Podstawową jednostką wyróżnianą w tej metodzie jest sekwencja depozycyjna, definiowana jako genetyczne następstwo powiązanych ze sobą warstw, ograniczone w spągu i stropie poprzez subaeralne niezgodności lub ich korelatywne zgodności (granic sekwencji), które są wynikiem zmian względnego poziomu morza, towarzyszących wypełnianiu basenów sedymentacyjnych. Przedstawiona próba interpretacji materiałów sejsmicznych, obejmująca mioceńską sukcesję nadewaporatową w rejonie Brzeska, na podstawie założeń tej metodyki i przy wykorzystaniu pomiarów geofizyki otworowej i ich wzajemnym dowiązaniu, pozwoliła na zidentyfikowanie 11 granic sekwencji (SB) i 9 powierzchni maksimum zalewu (MFS). W obrębie tych sekwencji, w zapisie sejsmicznym, karotażowym i w oparciu o dane literaturowe, zinterpretowano elementy architektury depozycyjnej zdominowane litofacją piaskowcową, deponowaną głównie w trakcie niskiego stanu WMP. Zostały one zinterpretowane jako nasypy przyujściowe/bary piaszczyste oraz fragmenty wciętych dolin w strefie szelfu.
Sequence stratigraphy is a multi-component tool for mapping the depositional architecture, sedimentary environments, lithofacies and their spatial distribution. The basic unit of distinction in this method is a depositional sequence, defined as a genetic consequence of interconnected layers, limited in the bottom and top by unconformities or corelative conformities (sequences borders). They are the result of changes in relative sea level that accompanies filling sedimentary basins. The study area included upper Badenian-lower Sarmatian (Miocen) strata in the region of Brzesko. Methodology used in conjunction with well logs and geological data allowed identification in the seismic 11 sequence boundaries (SB) and 9 of the maximum flooding surface (MFS). Within the sequence the elements of depositional architecture were interpreted. They were dominated by sandstone facies that had been deposited mainly during the low state of relative sea level.

Opis:
Tectonic deformation structures (folds, strike-slip, reverse and normal faults as well as joints) are reported here from the topmost part of the youngest, clayey sediments of the Carpathian foreland basin (Krakowiec clays, Sarmatian, Miocene), in a clay pit located at a village ofWylewa near Sieniawa. Our structural study has revealed several joint sets, accompanying products of intense folding and faulting, and defining a structural pattern that can be easily interpreted in terms of structures formed in a transpressive regime above strike-slip faults in the basement. The origin of these structures is ascribed to tectonic activity of the NW-SE-trending Ryszkowa Wola horst known to occur directly beneath the Wylewa clay pit, at a depth of c. 500 to 1300 m and to involve the basement and the lower part of theMiocene succession. The structural pattern in question most likely reflects a sinistral strike-slip displacement on sub-vertical boundary faults of the lowermost part of the horst. Undisputable effects of this strike-slip motion have been recently documented by other authors using 3D seismic data. The deformation structures at Wylewa must have resulted from a young, late to post-Sarmatian tectonic activity in the basement of the Carpathian foreland basin, probably reflecting an E-W to ENE-WSW directed regional shortening episode.

Nineteen samples were collected from four loess profiles: Dybawka, Tarnawce, Dankowice and Biały Kościół for purposes of TL and OSL dating. The samples were collected from loess, interstadial fossil soil, Eemian soil and Holocene soil. The results were presented in the form of TL=f (OSL) date chart. The majority of TL dates are older than OSL dates. The results of LMg luminescence dating run parallel to the straight line of equal ages. The chart shows a high similarity of TL and OSL dates. The results are consistent with the stratigraphic diagnosis. Loess grains frequently show an age heterogeneity (two or more OSL dates are provided for a single sample).

Opis:
Main geodynamic and tectonic mechanisms responsible for evolution of foreland basins and their sedimentary infill are discussed. They include flexure of the lower lithospheric plate and its extension, growth of the orogenic wedge and sedimentation / erosion within the foreland basin. Recently formulated models of foreland basin system include four major depositional zones that are characterised by various tectono-sedimentary processes. Of particular importance for evolution of foreland basins is very complex interplay of tectonics and sedimentation, and significant lateral shift of tectonic and depositional zones. Evolution of frontal part of the orogenic wedge could be deciphered using growth strata i.e. depositional sequences formed in vicinity of growing thrust-related structures. Certain aspects of Miocene (Late Badenian–Sarmatian) evolution of the Polish Carpathian foredeep basin are discussed in a context of presented models of foreland basins.
