Gdów “embayment”
Opis:
The Gdów “embayment” is the most pronounced deflection along the northern boundary of the Carpathians. It is filled by the sandy clay deposits which used to be named the Skawina Formation or Chodenice beds or, locally, conglomerates (of Sypka Góra). Their stratigraphic position according to studies of foraminifers had been determined as Badenian. New results obtained from micropalaeontological material sampled at three exposures near Wiatowice, Jawczyce (Giewont) and Gdów (Sypka Góra), and based on boreholes, indicate a much younger age of for the deposits infilling the Gdów “embayment”. These studies show that the surface deposits are not older than Late Sarmatian/Pannonian (Serravalian/Tortonian). They also suggest a much later time for the last stages of the thrusting of the Carpathian Mountains over the Carpathian Foredeep.

Opis:
The Carpathian Foredeep in Poland is divided into two parts, eastern and western, with different tectonic frameworks and conditions of the Neogene sedimentary fill. The boundary is the so-called Krakow Ridge associated with the contact of two regional tectonic units: Upper Silesian and Malopolska blocks. The width of the Foredeep varies regionally and significantly differs in the western and eastern parts. It was developed within the epi-Variscan platform. Two zones can be distinguished in the Foredeep: the inner (older) zone and the outer zone. The subject of the presented work is the eastern part of the outer zone of Foredeep located in front of the head of the Carpathian thrust and filled mainly by autochthonous Miocene formations. The meridional width of this zone of the basin varies from about 10 km in the vicinity of Krakow to nearly 100 km in the central part. Its tectonic framework is defined from the south and south-west by marginal structures of the Carpathian overthrust and tectonic units of the folded Miocene. From the north-east and north-west, the border is marked by a system of faults in the foreground of Roztocze Upland and the Holy Cross Mountains. In the Sub-Cenozoic basement, a set of large faults of NW-SE length, with different times of formation and activity, is marked. These faults locally define horst structures and tectonic grabens. Some of the faults continue under the Carpathians, under which there is also a system of transversal faults in relation to the main axis of the orogeny. The influence of the tectonic structures of the basement is noticeable within the Miocene cover by faults disappearing towards the surface and continuous deformations of the adaptive type. The outer foreland basin is filled with marine molasse type deposits of the unfolded autochthonous Middle Miocene with a thickness of up to approx. 3.500 m. The complex of Miocene formations is formed, in the lower, south-western and central part, by strongly differentiated submarine fan deposits accompanied by basin plain formations and gravitational flow deposits, including turbidite deposits characteristic of flysch sedimentation. The outer part of the fans smoothly transitions into the zone of fine-clastic sedimentation of the basin plain. Above the complex of submarine fan sediments, there are thick complexes of sediments of deltaic origin, which are also intensively variable facies, creating a set of channel (coarse-grained) and extra-channel (finegrained) facies. The highest, relatively thin part of the sediments is formed by shallow coastal shelf formations. Submarine fans and river deltas developed mainly in the zone of the south-western and southern coasts of the Miocene reservoir, surrounded by river mouths providing an abundant supply of material from the rising and eroded Carpathians. In the north-eastern and locally even in the middle part of the basin, sediments may appear, for which the feeding area was located in the hinterland of the northern and north-eastern coast of the Miocene Sea. The limited scope of extraction of drill cores resulting from the exploratory and exploitation nature of drilling makes it necessary to use borehole and surface geophysical data to reconstruct the depositional architecture. Processing and interpretation of geophysical data for a complex of Miocene sediments with such characteristics are problematic and ambiguous. Numerous sources of sedimentary material supply in the form of river mouths and submarine channels cause a significant diversification of the depositional architecture of the Miocene basin, making it difficult to trace uniform stratigraphic and lithological and facies boundaries. Sedimentary conditions cause, on the one hand, a certain monotony of the sediments, dominated by clastic formations, enriched by evaporate sediments horizons, and on the other hand, great lateral and depth facies differentiation. Geophysical well-logging data allows to recognize the lithological and facies variability of sediments and to determine the sequence of changes along the borehole trajectory. Seismic reflection data was used to track lateral variability. For the seismic reflective method, the reflective boundaries, characterized by a significant, abrupt change in acoustic impedance, are of primary importance. Within the Miocene basin, numerous reflective boundaries with high lateral variability and non-obvious stratigraphic identification are observed. In a complex of siliciclastic deposits, seismic wave reflections are recorded from the boundaries separating fine-grained lithofacies and medium- and coarse-grained facies. Due to the dominance of deltaic sediments and submarine fans in the depositional architecture of the Miocene complex, the regional continuity of such boundaries is problematic, and their unambiguous stratigraphic identification is practically impossible. To sum up, intense lithological and facies variability of clastic deposits, both lateral and vertical, should be expected within the Miocene complex. The sediments of individual fragments of submarine fans and deltas overlap each other, and there may also be overlaps with the sediments of neighboring fans. Such characteristics of the complex translate into a variable seismic pattern with numerous reflective boundaries and intense lateral variability of the seismic signal characteristics

The article presents the results of the reinterpretation of the results of the two-cycle DST of the Mesozoic strata in the W-3 well to assess the changes in permeability of reservoir rocks in the test zone. Two-dimensional diagrams of the first and second pressure restoration curves in the semi-logarithm coordinate system were taken into account. The determined linear regression equations of these sections give simultaneously the extrapolated value of the reservoir pressure and the directional coefficient. The “logarithmic approximation” method used in hydrogeology was used to determine the radius of the perimeter zone with altered permeability of the water-bearing rocks of the Mesozoic.

Opis:
Alabaster is a rock with low hardness, high coherence, fine-crystalline development and forms an optically “warm” surface when polished. It has been used as a sculpting, decorative and architectonic stone, often by civilizations of the Mediterranean Sea Basin. Alabaster in the architecture and sculpture of Kraków is mainly from the Middle Miocene (Badenian) and comes from deposits within the Ukrainian Carpathian Foredeep Basin, chiefly along its northern margin in the “Podolia rim”. It was quarried around the mid-part of the Dnister River and its tributaries, from Lviv (Lwów) to Khotyn (Chocim), and mostly at Zhuravno (Żurawno). The alabaster quarried here was called Ruthenian, Polish, or Lvov “marble”. Small quarries were also located at the front of the Carpathian overthrust, including the known deposit at Łopuszka Wielka. The Miocene alabaster has shades of white, yellow, green, brown, usually with differing spots or veins; often the rock is brecciated and partly semi-transparent. Alabaster has been quarried in the Polish Republic since the 16th century, peaking (also in finished stone products) between the world wars. The authors present examples of alabaster usage in ecclesiastical edifices of Kraków, for instance in the Wawel Cathedral, St. Mary’s Church, the churches of Dominican, Carmelite and Missionary clergy, and also in some secular buildings, e.g. the Jagiellonian Library.

Opis:
The facies variation of the Badenian sulphate deposits in the Polish Carpathian Foredeep Basin reflects distinct depositional and diagenetic environments. In these environments the primary sulphate (mainly gypsum) was deposited and then underwent different pathways of diagenetic evolution, recognized on the basis of sedimentological, petrographic and geochemical studies. Diagenetic sulphate facies (anhydrite and secondary gypsum) formed in successive stages: syndepositional (the depositional stage), early diagenetic (at the surface and during shallow burial) and late diagenetic (during deeper burial and exhumation). Most anhydrite deposits show sedimentological and petrographic features characteristic of a diagenetic facies formed by replacement (anhydritization) of the precursor gypsum deposits. Four basic genetic models of anhydrite have been proposed: (1) syndepositional interstitial anhydrite growth de novo, (2) syndepositional anhydritization (via nodule formation and pseudomorphous replacement), (3) early diagenetic anhydritization (displacive anhydrite growth), and (4) late diagenetic anhydritization (replacive anhydrite growth). The succession of diagenetic processes and their paragenetic relationships within the Badenian sulphate deposits display a complex diagenetic evolution. Many controlling factors, such as a palaeogeographic setting, tectonic activity, geostructural constraints and physico-chemical changes of the pore fluids, related to sedimentary and diagenetic environments, have been involved in the sulphate diagenesis. The results may be applied to other ancient evaporite basins including the marginal gypsum deposits and anhydrite in the more buried, basinward part.

Opis:
The sub-Quaternary topography of the western Sandomierz Basin has been compared to variable thicknesses of Quaternary sediments and geomorphology of the area. The lithology and age of the top of Miocene strata have been determined. The Witów Series has been interpreted as a sequence of a braided river that used to flow into the retreating marine basin, forming a fan delta whose age, according to macrofloristic determinations, has been assigned to the Late Miocene. Lower Quaternary gravels cap the remnants of a planated surface situated at 240-250 m a.s.l. The Błonie gravel horizon occurring at a similar altitude was deposited by a river active in Narevian and/or Nidanian glacial stages, and its top underwent reworking during the Sanian-2 stage. Deposits infilling the fossil sub-Carpathian Furrow have been mapped and dated to the Cromerian s.l. interglacial stage. The final alluviation of this segment of the furrow took place during the Sanian-2 stage. Reconstruction of the drainage pattern during the Eopleistocene, South-Polish glaciations, and Masovian inter- glacial stage has been proposed as well.

Opis:
Geochemical characteristics of 25 oils collected from Skiba Unit of the Outer Carpathians, Boryslav-Pokuttya Unit of the Carpathian Foredeep and their Mesozoic basement in the western Ukraine are presented in the paper. The first recognised oil family consists of almost all oils accumulated in the flysch sequence of the Outer Carpathians and the Carpathian Foredeep which have very similar geochemical characteristics. These oils were generated from Type II or II/III kerogen deposited in clastic sediments. They are low-sulphur and migrated short distances. Slight biodegradation processes are visible only in oils accumulated in shallow deposits in the Skiba Unit. Their source rocks are the Oligocene Menilite Shales from the Boryslav-Pokuttya Unit. Oils from the Kokhanivka and Orkhovychi deposits (the Mesozoic basement of the Carpathian Foredeep) constitute the second family. These oils are extremely heavy, high-sulphur and were generated from high-sulphur Type IIS kerogen deposited in the carbonate environment. The most probable source rocks for these oils are the Upper Jurassic strata. Oil collected from the Vola Blazhivska deposit (the Boryslav-Pokuttya Unit) shows intermediate parameters between the oil families described above. It is characterized by the presence of oleanane and high sulphur content. It was generated from the Menilite Shales containing high-sulphur kerogen. All oils were generated at an early stage or the peak of oil window.

Opis:
Multiproxy sedimentological, gamma-spectrometric, foraminiferal, calcareous nannoplankton, and otolith data were used for the reconstruction of the Badenian (Middle Miocene) history of the Moravian part of the Carpathian Foredeep. The study material originated from the new borehole LOM-1, which drilled >20 metres of monotonous clayey siltstones with exceptionally rich and well-preserved microfossil assemblages. Distal parts of the Carpathian Foredeep (a forebulge depozone) are exposed in this succession. Generally, a quiet environment of outer shelf to upper bathyal of monotonous clayey silts was interpreted, which is typical for the proximal parts of a peripheral foreland basin. The section studied can be subdivided into six intervals, confirming the cyclical character of Middle Miocene sedimentation in the Central Paratethys. Interannual oscillations of nutrient content, temperature and/or salinity are interpreted based on the oscillations of geochemical as well as palaeobiological data. The turnover connected with the initiation of the Middle Miocene Climatic Transition is recorded above the LO (last occurrence) of Helicosphaera waltrans in agreement with previous observations in the Carpathian Foredeep. The changes include cooling, a decrease in nutrients, a probable increase of the salinity of surface water, and increase of seasonality. Seasonality was manifested by an alternation of mixed and stratified water columns with a seasonal input of nutrients. Concerning nutrients, sources of seasonal riverine input or seasonal upwelling are both possible.

This paper documents the presence of Eocene marine strata in the Carpathian Foredeep area in Poland. Assemblages of marine dinoflagellate cysts have been found in sands penetrated by the Łukowa-4 borehole below the Miocene succession of the foredeep. Their age is interpreted as Late Eocene. The presence of marine strata of this age in this area sheds new light on the palaeogeography of the Carpathian foreland during the Late Eocene. The dinoflagellate cysts described are compared with coeval Carpathian and epicontinental assemblages; possible connections between these two basins are discussed. Phytogenetic deposits that occur above the marine sands of the Łukowa-4 borehole contain freshwater palynomorphs, indicating their swamp and lacustrine origins. The overlying sand contains impoverished dinoflagellate cyst assemblages; their age is discussed.

Wieliczka salt deposit
Opis:
Salt deposits in the Wieliczka area (Wieliczka Salt Deposit – WSD) in southern Poland comprise salt-rich strata belonging to an evaporite succession that originated in the Carpathian Foredeep basin in the Middle Miocene Badenian (Serravallian) times, ca 13.81–13.45 Ma. Although they have been mined since the 13th century and decades of investigations provided abundant data on their origin and structure, some aspects of their geological evolution are still not fully understood. This study presents current concepts on the lithostratigraphy and tectonics of the WSD. The salt-bearing facies developed near to the southern basin margin, delineated by the Carpathian orogenic front. Such a location triggered the redeposition of sediments and gravity-driven deformation followed by tectonic deformation related to the forelandward advancement of the Carpathian thrusts. As a result, the WSD consists of folds and slices composed of two main salt members: (1) the stratified salt member, with intercalating salt, sulphates and siliciclastics, and (2) the boulder salt member, built of clays with large, isolated blocks of salt. The stratified member contains abundant meso-scale tectonic structures recording the soft-sediment deformation and deformation related to the northward tectonic push exerted by the advancing Carpathian thrust wedge. The boulder member originated due to the syntectonic erosion of evaporites along the basin margins and their redeposition during progressive northward migration of the Carpathian front. Recent interpretations of seismic data imply that the WSD constitutes the core of a triangle zone developed at the contact of the Carpathian orogenic wedge with the backthrust-displaced foredeep sedimentary fill. Meso-scale examples of sedimentary and tectonic structures in the salt-bearing succession exposed in the underground Wieliczka Salt Mine are described and their formation modes discussed.

Study of foraminiferal and dinoflagellate cyst assemblages and palynofacies occurring in 2 m-thick marls cropping out beneath a giant gypsum intergrowth unit in the Borków gypsum quarry in Southern Poland, one of the key Badenian evaporite sections in the Polish Carpathian Foredeep Basin, has shown the presence of 49 species of benthic foraminifers and 11 species of planktonic ones, and 51 dinoflagellate (including 8 redeposited ones). The composition of the foraminiferal fauna and its isotopic signal indicate temperature-stratified, nutrient-rich and thus less-oxygenated marine water. Changes in the relative abundance of epifaunal and infaunal species indicate a clear environmental change during the deposition of the marls. A middle to outer shelf marine, well-ventilated environment with moderate primary productivity existed during the deposition of the bottom part of the marls. Subsequently, infaunal bottom-dwellers became dominant due to a massive increase in food supply to the sea bottom and shallowing of the sea to inner - middle shelf depths, and than a decreasing trend of a relative abundance of the infaunal morphogroups is observed until the top of the marls that were deposited in an inner shelf environment with moderate primary productivity. The calculated palaeotemperatures for particular foraminifer taxa (Globigerina spp., Cibicidoides and Bulimina elongata) show a slight upsection decrease and a decrease in the temperature differences between the bottom and intermediate water beds. Palynofacies are composed of elements of mixed origin, including terrestrial, marine (mainly dinoflagellate cysts) and elements of uncertain derivation (structureless organic matter). The palynological content of most samples indicates their deposition in an open-marine marine environment, in the stable marine conditions of an open shelf basin with no salinity fluctuations. The sample just below the gypsum contains no dinoflagellate cysts, perhaps due to a drastic change in the photic zone leading to a complete collapse of the dinoflagellate flora. Very rare occurrence of planktonic foraminifers in that sample suggest the shallowing of the basin accompanied by a decrease in the temperature gradient between the upper (warmer) and lower (colder) water beds. A shallow, cold water marine environment is indicated for the topmost foraminiferal assemblage.
