Abstract
The evolution of the deep-sea sedimentation system in the north-eastern part of the Black Sea during the Oligocene-Pliocene is considered mainly on the basis of seismic data. The fans and erosion canyons formation time is presumably related to the regressive-transgressive stages in the history of the Eastern Paratethys. The source areas of detrital sediments in the Tuapse Trough are identified. The sedimentation model of the Tuapse Trough and the changes in the Trough’s morphology since the Oligocene were reconstructed based on the analysis of the thickness maps and the onlap surfaces on the northern side of the Shatsky Swell. Paleogeographic maps were compiled for the Late Oligocene-Early Miocene (Maikop), Middle Miocene, and Pliocene.
