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.
