Abstract:
The study of the source rocks was carried out with the use of various analytical methods in order to assess their generation potential and to predict the decomposition products of organic matter. The selected samples from the Menilite Beds from the Silesian and Dukla units, as well as the Istebna layers from the Silesian unit, which are classified as weak and medium source rocks in the Carpathian oil system, were examined. The generation potential and type of the products obtained from the pyrolysis of the analyzed source rocks, despite the often comparable overall content of organic matter, are significantly different. Menilite shale generated a higher abundance of hydrocarbons (alkanes, alkenes, and isoalkanes) by stage pyrolysis, which suggested that the organic matter of Menilite shale is different from the Istebna source rocks. Moreover, the thermogravimetric analysis showed a two-stage weight loss in the case of Menilite shales, while the Istebna shales were characterized by a one-stage weight loss at higher temperature. For the Istebna layers, n-alkanes from the C1–C5 range were detected as the main pyrolysis products, which proves the gas-forming type of the organic matter dispersed in these sediments. Rock-Eval analyses showed that the organic matter reached a degree of maturity corresponding to the early thermocatalytic processes (the initial oil window stage) and therefore was able to generate liquid and gaseous hydrocarbons. The comparison of the decomposition temperatures of the organic matter from the Rock-Eval and TG analyses allowed us to conclude that both measurements correlate well and can be equally used to assess the level of thermal transformations of organic matter.

Abstract:
Abstract Molybdenum is one of the major trace elements for plants, but its excess and the deficiency of copper in soils can lead to the production of feed that may be toxic to animals and cause molybdenosis. Menilite shales that occur in the Eastern Beskids Mts. are characterised by an elevated content of this element. The concentration of molybdenum and copper has been determined in samples of bedrock, soils and plants (Trifolium hybridum L. and Plantago major L. plants), taken in the area of occurrence of menilite shales and the Otryt Sandstones. The molybdenum concentration in rocks varies from 0.80 to 40 mg/kg, in soils - from 1.97 to 19.58 mg/kg, and in plant material - from 0.54 to 11.76 mg/kg. The copper concentration in rocks ranges from 11 to 111 mg/kg, in soils - from 23 to 76 mg/kg, and in plants - up to 20 mg/kg. The average Mo concentration in all kinds of plants is significantly higher in the area of occurrence of menilite shales than in the area where the Otryt Sandstones are dominant. The higher content of Mo in the samples collected from clover was accompanied by the lower Cu/Mo ratio, which may cause a molybdenosis disease in animals in the study area.

Abstract:
Paleoecology of the Upper Eocene-Lower Oligocene Malcov Basin based on the calcareous nannofossils: a case study of the Leluchów section (Krynica Zone, Magura Nappe, Polish Outer Carpathians)During the period of ca. 20 Ma (Middle Eocene-Chattian) the Leluchów Succession of the Magura Basin passed through drastic changes of sedimentary condition and paleobathymetry from well oxygened red shales withReticulofragmium amplectens, deposited beneath CCD, redGlobigerinaoozes, to oxygen depleted organic-rich menilite-type shales and finally to flysch deposition of open marine conditions. The biostratigraphic and lithostratigraphic scheme is well established with the Leluchów Marl Member — Zones NP19-20 to NP22 (Late Eocene-Early Oligocene), Smereczek Shale Member, Zone NP23 (Early Oligocene) and the Malcov Formation s.s., Zone NP24 (Early-Late Oligocene). The aim of the paper is to present the quantitative analyses as the basis for paleoecological changes in the Magura Basin during the Late Eocene-Late Oligocene period. The changes manifest themselves through a decrease in the water temperature and progressing eutrophication. Species typical of brackish water conditions and restricted to the Paratethys region were identified from the NP23 Zone.

Abstract:
Celem pracy było scharakteryzowanie przestrzeni porowej łupków menilitowych występujących w odsłonięciach powierzchniowych z rejonu Birczy w jednostce skolskiej. Wszystkie próbki zostały pobrane z całego profilu stratygraficznego w jednym odsłonięciu w Birczy o długości 1 m. Struktura porowa próbek łupków wygrzanych w 105°C była mierzona metodą porozymetrii rtęciowej (ang. mercury injection capillary pressure, MICP) w temperaturze otoczenia oraz metodą adsorpcji azotu w temperaturze wrzenia ciekłego azotu. Ze względu na deformację przestrzeni porowej pod wpływem wysokich ciśnień roboczych rtęci, z krokami ciśnienia od 0 do 4136,84 bara, mikropory i mezopory można błędnie interpretować. Jako metodę uzupełniającą zastosowano więc pomiar adsorpcji azotu w celu prawidłowego obliczenia całkowitej połączonej objętości porowej. Na wykresach dV/dD (pochodnych objętości względem średnicy) połączono wyniki z obu technik pomiarowych, uzyskując pełniejszy obraz rozkładu objętości porów. W pracy przedstawiono możliwość dokładniejszego obliczenia objętości porów na podstawie nowego podejścia do analizy wykresów pochodnych. Obie metody zapewniają również kompleksową ocenę parametrów struktury porów, w tym powierzchni właściwej (ang. specific surface area, SSA), objętości mikro- i mezoporów oraz rozszerzonego zakresu rozkładu wielkości porów (ang. pore size distribution, PSD). Porównując wyniki metody adsorpcyjnej z użyciem azotu z wynikami porozymetrii rtęciowej, należy pamiętać o różnicach w zakresach obu technik badawczych oraz o tym, że azot i rtęć rejestrują struktury porowe w znacząco odmienny sposób. Zatłaczanie rtęci do struktury porowej jest regulowane przez przewężenia porów, podczas gdy zjawisko adsorpcji jest kontrolowane przez powierzchnię porów. Zastosowanie porozymetrii rtęciowej i adsorpcji azotu do łupków menilitowych pokazuje, jak użycie tych dwóch metod może wpłynąć na uzyskanie wzajemnie uzupełniających się informacji, które weryfikują obliczenia objętości porowej głównej skały macierzystej dla karpackich rop naftowych.

Abstract:
For the first time in the Ukrainian Carpathians, the depths and tectono-sedimentation processes in the north-eastern part of the Outer Carpathian Basin (Skyba and Boryslav-Pokuttya units) have been restored on the base of sedimentological and microfaunistic studies. It was established that in the Cretaceous-Eocene time, the deep-water (near Calcite Compensation Depth) turbidite and similar sedimentation (turbidites with Bouma textures, grainites, debris-flow deposits), which periodically alternated with (hemi)pelagic sedimentation (red, green and black shales) was dominant here. Sedimentation took place on the continental margin of the the Carpathian branch of the Tethys, where deep-water fans were formed. Cretaceous-Eocene background red and green shales are enriched in buried in situ benthic foraminifera which are similar in taxonomic composition and morphological features to the microfauna of the Carpathian-Alpine and Atlantic regions (deep-water agglutinated foraminifera), which indicate lower bathyal – abyssal depths of flysch sedimentation. Latest Eocene Globigerina Marl horizon contains the foraminiferal assemblage with plankton dominance, which indicates a general shallowing of the Outer Carpathian Basin (middle-upper bathyal conditions above a calcite compensation depth). Oligocene – lowermost Miocene Menilite-Krosno and Polyanytsia formations were accumulated in the Skyba and Boryslav-Pokuttya sub-basins. In the Miocene, shallow-water molasses were accumulated here. Probably, the tectonic uproot of flysch deposits from its substrate and their synsedymentary thrusting towards the platform caused a significant shallowing of the Skyba and Boryslav-Pokuttya sub-basins starting from the latest Eocene. These processes reflected the growth of the Carpathian frontal nappes at the final orogen formation stage.

Abstract:
Hydrocarbon exploration under thrust belts is a challenging frontier globally. In this work, 1-D thermal maturity modeling of the Paleozoic–Mesozoic basement in the northern margin of the Western Outer Carpathians was carried out to better explain the thermal history of source rocks that influenced hydrocarbon generation. The combination of Variscan burial and post-Variscan heating due to elevated heat flow may have caused significant heating in the Paleozoic basement in the pre-Middle Jurassic period. However, the most likely combined effect of Permian-Triassic burial and Late Triassic–Early Jurassic increase of heat flow caused the reaching of maximum paleotemperature. The main phase of hydrocarbon generation in Paleozoic source rocks developed in pre-Middle Jurassic times. Therefore, generated hydrocarbons from Ordovician and Silurian source rocks were lost before reservoirs and traps were formed in the Late Mesozoic. The Miocene thermal overprint due to the Carpathian overthrust probably did not significantly change the thermal maturity of organic matter in the Paleozoic–Mesozoic strata. Thus, it can be concluded that petroleum accumulations in the Late Jurassic and Cenomanian reservoirs of the foreland were charged later, mainly by source rocks occurring within the thrustbelt, i.e., Oligocene Menilite Shales. Finally, this work shows that comprehensive mineralogical and geochemical studies are an indispensable prerequisite of any petroleum system modelling because their results could influence petroleum exploration of new oil and gas fields.

Abstract:
Abstract Purpose Literature reported that soils characterized by heterogeneity would reveal the different direction of clay minerals transformation. Hence, in this study, four soils developed on menilite shales slope deposits were investigated to test if the clay minerals transformations in soils with varied calcium carbonate distribution would show multidirectional paths of clay mineral weathering, or if transformation of secondary phases in such stratified materials would reveal only one trajectory. Methods The separated clay fractions were analysed using X-ray diffractometry and Fourier-transform infrared spectroscopy. Geochemical analyses were performed using ICP-ES and ICP-MS after sample fusion with lithium borate and an alloy dissolution with nitric acid. Results Calcium carbonate did not influence the composition and transformation of clay minerals. Despite the fact that soils were characterized by different content and distribution of calcium carbonate within the solum and additionally indicated various morphological features, the mineralogical composition of clay fraction was very uniform. Among the secondary phases, chlorite, illite, vermiculite, kaolinite and mixed phases illite-smectite and vermiculite-chlorite were detected in all horizons. Conclusions The uniform composition of the clay minerals in the studied soils suggested that mass movement, which controlled the formation of slope covers, was probably of a similar character and intensity across the whole of the slope. Furthermore, it seems that the pedogenesis in all soils proceeded on the same scale of advancement. This was indicated by a similar degree of weathering of soil material and lack of depth-dependent weathering in the profiles, confirmed by values of weathering indices (CIA and ICV) as well as by micromorphologically visible, highly weathered coarse fragments. Moreover, weak intensity of the illuviation process within the homogeneous substrate could have resulted in the very uniform composition of clay minerals in the studied soils.

Abstract:
Eocene-Oligocene sedimentation in the external areas of the Moldavide Basin (Marginal Folds Nappe, Eastern Carpathians, Romania): sedimentological, paleontological and petrographic approachesThe Marginal Folds Nappe is one of the most external tectonic units of the Moldavide Nappe System (Eastern Carpathians), formed by Cretaceous to Tertiary flysch and molasse deposits, piled up during the Miocene closure of the East Carpathian Flysch basin, cropping out in several tectonic half-windows, the Bistriţa half-window being one of them. The deposits of this tectonic unit were accumulated in anoxic-oxic-anoxic conditions, in a forebulge depozone (sensuDeCelles & Giles 1996), and consist of a pelitic background sporadically interrupted by coarse-grained events. During the Late Eocene the sedimentation registered a transition from calcareous (Doamna Limestones) to pelitic (Bisericani Beds) grading to Globigerina Marls at the Eocene-Oligocene boundary, and upward during the Oligocene in deposits rich in organic matter (Lower Menilites, Bituminous Marls, Lower and Upper Dysodilic Shales) with coarsegrained interlayers. Seven facies associations were recognized, and interpreted as depositional systems of shallow to deeper water on a ramp-type margin. Two mixed depositional systems of turbidite-like facies association separated by a thick pelitic interval (Bituminous Marls) have been recognized. They were supplied by a "green schists" source area of Central Dobrogea type. The petrography of the sandstone beds shows an excellent compositional uniformity (quartzarenite-like rocks), probably representing a first cycle detritus derived from low rank metamorphic sources, connected with the forebulge relief developed on such a basement. The sedimentation was controlled mainly by different subsidence of blocks created by extensional tectonic affecting the ramp-type margin of the forebulge depozone.

Abstract:
Studies of molybdenum and manganese content in topsoil and plants were carried out in the Beskidy Wschodnie (Carpathians) in area of occurrence of menilite shales and the Otryt sandstones. The aim of the study was to evaluate the content of ­molybdenum and manganese in plants and the determination of a bioaccumulation of these two chemical elements in two species of plants (­Trifolium hybridum L. and Plantago major L.). Mo symbols were performed by means of ICP-MS method, and Mn were analyzed by means of ICP-OES method. Result of studies in the Trifolium hybridum L. have shown higher content of Mo in the area of occurence of menilite shales (in leaves – 14 mg/kg) than in the Otryt sandstones (in leaves – 0.30 mg/kg). Most Mn accumulates in leaves (86–257 mg/kg). The bioaccumulate indicator of Mo in individual plant species is different and ranges from 0.13 to 1.13. The highest rate of ­bioaccumulation of molybdenum (1.13) can be observed in Trifolium hybridum L., which inhabits areas of menilite shales.

Abstract:
Purpose. On the territory of the Ukrainian Eastern Carpathians there are sedimentary rocks characterized by a great content of hydrocarbons. Among them, the so-called "menilite shale" deserves special attention. In reality, "menilite shale" is black and dark gray argillites. They form the bulk of the Menilite suite of oligocene of the Precarpathian Foredeep Inner zone and the Plicate Carpathians. These argillites represent a convenient and easily accessible object for study, as there are numerous exits of these rocks on the surface in the Eastern Carpathians. The menilite suite is a massive formation, the thickness of which sometimes reaches1500 m. Our aim is to study the structure of the bitumen of the menilite suite argillites and to calculate redistribution of structural elements in hydrocarbons, which occurs with increasing temperature. Method. In order to perform the work, we have applied methods of equilibrium thermodynamics and Jaynes' formalism. The basis for algorithms creating was thermodynamics of maximum entropy, which combines techniques from Claude Shannon's information theory, Bayesian probability, and the principle of maximum entropy. Based on Jaines's formalism, we have developed a method for determining the quantity of structural elements in black argillites bitumen. Output data for calculation was layers temperature and elemental composition of the sample. The calculations were carried out within the temperature range 300-600 K (27-327 °С). Results. The result of calculation is the distribution of atoms, which composes bitumen in functional groups, depending on the temperature. It is established that with increasing temperature the value of Gibbs free energy increases with linear dependence, along with nonlinear growth of entropy. As the temperature rises, relative amount of the methyl group (-CH3) decreases, together with the increase in the number of other components of alkanes. It has also been established that the process of cyclization of hydrocarbon compounds takes place with the submergence of the rock. It is shown that among the sulfur-containing groups the content of cyclic sulfur is increasing most rapidly with increasing temperature. As the temperature increases, a significant rise in the relative proportion of the nitrile group is observed. Simultaneously, the process of aliphatic structures destruction containing Nitrogen (for example a primary amino group) is occurring. Scientific novelty and practical significance. We show that the Jaynes' formalism can be successfully applied to establishing redistribution of atomic groups of fossil hydrocarbons, which occurs in changing geological conditions – submergence and emergence. Flexibility of the method allows us to expand the list of conditions, including adding other structural units or individual components: gases, liquid hydrocarbons, etc.
