Some indication for late quaternary Pechora River discharge: results of vibrocore studies in the southeastern Pechora Sea

The study of Upper Quaternary sedimentary sequences in the Pechora Sea by m eans of vibrocoring revealed three sediment units. The (youngest) sandy uni t accumulated in marine environments later than 5000 years B.P. The clayey unit belongs to a pro-deltaic facies, probably formed during Middle Holocen e times. The diamict unit formed during Middle/Early Weichselian times, pro bably has a glacigenic origin and is separated from the clayey unit by a hi atus. The changes in lithology are partly related to changes in Pechora Riv er discharge during late Weichselian/Holocene times.
