Abstract
The results of granulometric analyzes of the basal Neopleistocene moraines from sections of coastal outcrops and boreholes in the vast territory of the European Subarctic of Russia and in the more southern regions of the Timan-Pechora-Vychegoda region have been summarized. It showed that moraines are typical mixed, practically unsorted rocks with similar contents of gravel-sand, silt, and clay fractions, which is one of arguments is in favor of thear glacial genesis. Their granulometric composition is due to the peculiarities of the rocks of the ice bed.It is formed in the process of crushing, abrasion, and mixing of material assimilated and transported by the glacier during its transportation and deposition, which determines the variability of the granulometric composition of moraines. As a result, the granulometric composition of the moraines in combination with other lithological data reflects the path of the glacier and the dynamics of its movement.
