Abstract

Geological-geophysical data show that the Holocene marine and Late Glacial glaciomarine sediments in the eastern part of the Barents Sea are seismostratigraphic complexes (SSCs), SSCI and SSCII, respectively. SSCII sediments composed of glacial mineral matter were formed during deglaciation of the Barents Sea shelf. The SSCI sediments deposited in the setting of the open sea basin are terrigenous. The structure, composition, and thicknesses of the SSCII sediments are determined by the thawing of degraded glacier masses and by the character of the resulting sedimentation basins, while the same parameters of the SSCI sediments are determined by the hydrodynamics and, partially, by processes of the last glacioeustatic marine transgression.
