Abstract
The results of lithological studies of Quaternary deposits in the coastal outcrops of the valley of the lower course of the river are presented. Pechora. In the latitudinal section of the Pechora, two horizons of boulder loams (moraines) and underlying horizons, dividing or overlapping the moraine strata, are exposed to intermoraine sediments of fluvial genesis. Based on the results of lithological studies of textural, granulometric and mineralogical features of fine earth of deposits and petrographic composition of coarse material, it was concluded that material was supplied during the formation of moraines from different terrigenous-mineralogical provinces. The formation of the lower Pechora (Dnieper) moraine is associated with the North-Eastern feeding province, and the upper Moscow (Vychegda) moraine, with the North-West Fennoscandian center of glaciation. The glacial genesis of boulder loams has been confirmed.
