Abstract

Seismic survey data interpretation resulted in describing six overlapping accumulative sequences forming the Don–Kuban deep sea fan. Three lower sequences belong to the Don fan in the mouth of canyons abeam of the Kerch Strait. Three upper sequences records present systems of channels, levees, suprafans relative to the Don fan and Kuban fan pertinent to the Anapa canyon. In the records, identification of six Don–Kuban deep sea fan sequences, which correspond to the Neopleistocene superhorizons (climatorythms), facilitates seismic stratigraphic subdivision of the Neopleistocene sediments section in the Black Sea abyssal basin. The Don–Kuban deep sea fan section can refer to a key seismic stratigraphic section, stratotype of the Neopleistocene stratigraphic boundaries of the abyssal basin.
