Abstract

Geological-geophysical dates are showing that Holocene marine and Late Glacial glaciomarine sediments in the eastern Barents Sea represent seismostratigraphic complexes (SSC), accordingly SSCI and SSCII. Th e composed of glacial mineral matter sediments SSCII formed in the time of the Barents Sea shelf deglaciation, but the sediments SSCI deposited in conditions of open marine basin and are terrigenious. Features of the structure, composition and thicknesses of sediments SSCII are defi nite by melting conditions of degraded glacier masses and by character of originated sedimentation basins, but of sediments SSCI — by hydrodynamic factor and, partially, — by processes of last glacial eustatic marine transgression.
