Geological research in Gorlice region has revealed existence of chaotic complexes “block in matrix” type. These chaotic complexes usually were taken for some “flysch” members as e.g. variegated shales, or Inoceramus beds, The research have also revealed chaotic character of the so called Łużna and Harlkowa “peninulas” and outliers and confirmed Mio...

Studies were conducted i the Outer Carpathians in the area of the Western and Eastern Carpathians in the borderland of Poland, Slovakia and Ukraine. The character of anoxic facies in the Carpathians in the Polish and Slovak area within different tectonic units – from the Dukla unit trough the Silesian, Boryslav-Pokuttia, Skole and Węglówka unit was...

The article presents a new concept of structural control on the Outer Carpathians relief. The Carpathians’ relief development originated in the stage of sedimentary basin deposition(e.g., gravitational positioning of fragments of rock massif), as well as in the compressional stage of the orogen formation, and, finally, in the stage of secondary tec...

This paper presents a description of the outcrops selected for new conception on structural geology and Carpathian Petroleum System. The description includes 11 outcrops; from Bandrów to Grybów area. The outcrops reveal the profile of the Carpathians including relevant elements of the Carpathian Petroleum System i.e. source and sealing rocks. In th...

Celem artykułu jest zwrócenie uwagi na problem tzw. rekultywacji naturalnych wycieków ropy naftowej, występujących często w Karpatach. Wieloletnie obserwacje wskazują, że ich szkodliwość i wpływ na środowisko są raczej niewielkie (jakkolwiek zagrożenie istnieje), natomiast stanowią one istotny przedmiot badawczy dla wielu dziedzin nauki i mają znac...

New concepts of the development of the Pieniny Mts. (geologically the Pieniny Klippen Belt) as a regional flower structure, as well as a detailed analysis of the Digital Terrain Model (DTM), indicate that the Dunajec River Gorge in the Pieniny Mts. (called also the Pieniny Gorge) is regressive and structural. The Dunajec River, originally flowing a...

The Lanckorońsko-Żegocińska zone stretched from the Żegocina area to the Kalwaria Zebrzydowska area is a tectonic element with an oblique course in relation to the directions of the overhang zones of traditionally distinguished tectonic units. It runs independently of the course of the elements of the Silesian unit, in some areas it runs near the e...

Hand‐dug oil wells, located in natural crude oil seep sites, are remnants of historical exploitation activities. Hydrocarbon pollution is regarded as the threat to soil ecosystem. On the other hand, there is no common environmental policies regarding these soils. The hypothesis was that natural attenuation processes might occur in seep soils since...

Quartz, carbonates and other minerals as e.g., realgar are present in veins and caverns in sedimentary rocks in the Western Carpathians. In the Polish segment, they have been characterized from the mineralogical, petrologic, and geochemical points of view, as well as fluid inclusions. Their characters are discussed from perspective of a description...

The paper presents a new concept of geological control of the Outer Western Carpathians (OWC) morphology. The establishment of the Carpathians' morphology dates back to the stage of evolution of sedimentary basin, when huge blocks of solidified rock massifs were gravitationally displaced into the foreland sedimentary basins, forming finally isolate...

The anisotropy of magnetic susceptibility is a well‐known geological proxy in revealing the directional tectonic and sedimentological features of rocks, although it can be ambiguous in situations where these two factors co‐occur. This paper demonstrates the usefulness of the anisotropy of magnetic susceptibility in determining palaeotransport direc...

In the Central Western Carpathians (CWC), most published paleomagnetic results from Permo-Mesozoic rocks document extensive remagnetizations and come from thin-skinned thrust units that have undergone multistage deformation.We present results from lower Triassic redbeds from the autochthonous cover overlying the basement that carry a primary magnet...

The irregular distribution of sand injections, traditionally termed ‘dykes’ in the Polish geological literature, within individual Carpathian units and within individual lithofacies were observed during long-lasting field works. Injectites have been observed in the Magura Beds and in the Inoceramian Beds of the Polish and Romanian Carpathians, and...

On the 2tlh of June 2017. the Polish Ministry of the Environment announced the boundaries of the 15 tender areas selected for the third licensing concession round for prospection, exploration and exploitation of hydrocarbons. In this paper we describe the areas located in the south-eastern (Ryki) and southern Poland (Proszowice W, Rudnik-Lipiny, Bl...

STRESZCZENIE: Dotychczas wykonane badania wykazały, że z jednej strony analiza maksymalnych paleotemperatur, jakim podlegały w swojej historii geologicznej skały odsłaniające się na powierzchni w Karpatach, pozwalają na wydzielanie bloków tektonicznych o różnym stopniu ekshumacji, a z drugiej strony pomiary wielkości koncentracji radonu w glebie po...

Radiometric K/Ar dating of glauconite and nanno- and micropaleontologic analyses of calcareous nannoplankton, foraminifers and dinoflagellates isolated from the Miocene rocks in the Polish part of the Roztocze region, a northeastern part of the fore-bulge of the Carpathian Foreland Basin System - CFBS), SE Poland, reveal that these strata contain n...

The Podolia region is located along the western border of the Eastern European Craton, which is also known as Ukrainian Shield. From the Ordovician to the Miocene, this area formed part of an epicontinental basin system. In order to investigate the effects of orogenic cycles occurring along the plate margin, a multi-disciplinary approach was used i...

Western Carpathian orogeny has been the subject of intense scientific debate due to the occurrence of enigmatic features, leading several authors to provide contrasting geological models. In this paper, a new interpretation for the tectonic evolution of the Western Carpathians is provided based on: (i) an analysis of the stratigraphy of the Mesozoi...

The Hamernia peat bog in the Roztocze region started to develop in the Allerød within the deflation basin divided into two sub-basins by a parabolic dune formed in the Older or the Oldest Dryas. Lithological and palynological analyses as well as radiocarbon dating of samples from three logs cored in different parts of the peat-bog indicate that up...

In this paper, a new approach is applied to test a proposed scenario for the tectonic evolution of the Western Carpathian fold-and-thrust belt- foreland system. A N-S balanced section was constructed across the fold-and-thrust belt, from the Polish foreland to the Slovakia hinterland domain. Its sequential restoration allows us to delineate the tec...

A new 240-km long, deep seismic reflection profile (POLCRUST-01) was recently acquired in SE Poland crossing the East European Platform (EEP) margin south-east of the North-German-Polish Caledonides (NGPC). Here we document geophysical field work and subsequent data processing and modelling. Results obtained from reflection seismic data are augment...

This study is devoted to chaotic complexes occurring in the Carpathian Mountains. Their genesis and location in the Carpathian orogen structure is discussed. Among different types of chaotic complexes revealing “blocks in the matrix” structure, the focus was put on tectonic mélanges, so far not mentioned in polish literature. In the study a controv...

The aim of the paper was to show possibilities of applying the relatively new, and quick FTIR molecular vibrational spectroscopy with Attenuated Total Reflectance – ATR technique – in order to correlate extracted organic matter samples of different types with its infrared spectra. The technique was employed for 22 shale rock samples of the Carpatia...

Teisseyre–Tornquist Zone (TTZ) corresponds to a crustal boundary between the Precambrian East European Platform (EEP) and the Palaeozoic West European Platform. Although the zone has been controlling Phanerozoic evolution of large parts of Central Europe, its course, geometry and origin are still poorly constrained. Deep reflection seismic profile...

he Carpathian-Pannonian region is made up of the wide extensional Pannonian Basin surrounded by the Carpathian mountain belt. The Pannonian Basin formed in the Miocene by extension in a retro-wedge position while thrusting was still active at the Carpathian front. The Ukrainian region is an ideal area to reconstruct the relationship between the Pan...

Biostratigraphic analysis of fossils material has allowed the documentation of sediment gravity flows in the Skole basin during the Paleocene and Eocene times, and also in the Eocene-Oligocene transition. This most external basin of the NE Outer Carpathians was a marginal sea especially sensitive to geotectonic instability and relative sea-level ch...

The research was carried out in different tectonic units of the Polish Carpathians. Three stages of migration were indentified with the use of fluidal inclusions in cements analyses and bitumen traces in the pore space. The main migration paths of hydrocarbons are usually mélange tectonic zones revealing signs of diversified mineralization. These o...
