A comparative analysis of sections of soil columns from the northern part of the Black Sea and the Northern and Middle Caspian Sea was performed. In the Black Sea, the New, Old Black Sea and New Evksin sediments were identified, the features of their lithological composition were revealed and the age of 14C was established. Shallow and deep-water Novocaspian, Mangyshlak, Verkhnekhvalynsky, Nizhnekhvalynsky, Athelsky and Hyrkan horizons are identified and correlated in the Caspian Sea. As a result, the identity of the structure of the continuous deep-water sections of the compared reservoirs and the synchronicity of the Novoevksin and Late Khvalyn layers are established, which suggests the absence of a connection between the Novoevksin and Early Khvalyn seas.
The sections of boreholes and sediment cores in the Taman shelf area and on the Caucasian continental slope, which uncovered shallow and deep-water facies of the interglacial Karangate horizon, were studied. The shallow-water sediments include clayey and sandy-shell varieties containing stenohaline marine molluscan fauna. Deep-water sediments are represented by sapropelic and coccolithic layers with a marine flora of diatom algae and coccolithophorids.
The Pontocaspian (Black Sea - Caspian Sea) region has a very dynamic history of basin development and biotic evolution. The region is the remnant of a once vast Paratethys Sea. It contains some of the best Eurasian geological records of tectonic, climatic and paleoenvironmental change. The Pliocene-Quaternary co-evolution of the Black Sea-Caspian Sea is dominated by major changes in water (lake and sea) levels resulting in a pulsating system of connected and isolated basins. Understanding the history of the region, including the drivers of lake level and faunal evolution, is hampered by indistinct stratigraphic nomenclature and contradicting time constraints for regional sedimentary successions. In this paper we review and update the late Pliocene to Quaternary stratigraphic framework of the Pontocaspian domain, focusing on the Black Sea Basin, Caspian Basin, Marmara Sea and the terrestrial environments surrounding these large, mostly endorheic lake sea systems. ; C1 [Krijgsman, W.; Lazarev, S.; Hoyle, T.
