Analysis of Gravitational Deposits at the Continental Slope of the Northeastern Part of the Black Sea

Abstract

Analysis of new 3D and 2D seismic data made it possible to describe the continental slope relief of the northeastern Black Sea in detail, and to reveal a large number of gravitational processes of various types. It was found that the final phase of active development of lithodynamic processes was caused by the New Euxinian regression associated with the last glaciation; this ended more than 10 000 years ago. Irregularities that formed as a result of late Holocene landslides also occur; however, their contribution is insignificant, with an amplitude rarely exceeding 1 m.
