Devonian

The purpose of this work is to study depositional history and the dynamics of post-sedimentary transformations, in particular the thermal maturity of kerogen in the Middle-Upper Devonian rocks of the Lviv Paleozoic Depression. Methodology. This study utilized an integrated approach involving geochemical analyses, specifically focusing on parameters of Rock-Eval pyrolysis such as total organic carbon content, temperature Tmax, S2 oil potential, and palynological studies that included the color index of microfossils. Results.

Purpose. The objective of this study is the investigation of the Silurian-Lower Devonian (Lochkovian) carbonate-clay sedimentary complex of the southwestern slope of the East-European platform. Its formation was the result of a single cycle of geodynamic and sedimentary events in the lithological record of the southern continental margin of Baltica. Methodology. The study is based on well-logs correlation, lithological and geochemical investigations of core samples, and petrographic thin sections analysis.
