Marginal glacial formations at NW Dnieper tongue areas as the basis for deglaciation stages reconstruction

Abstract

A distinct zonality of topography and glacial deposits has been established at NW of the area covered with Dnieper tongue of the ice sheet, the zonal pattern being formed by four bands of marginal glacial formations (MGP). As f ar as the geomorphology of MGF is concerned, they consist of glaciomorphic sectors, which in turn include marginal zones, the latter consisting of elementary forms.

Some features of the Dnieper tongue dynamics and geological activity during deglaciation are inferred from data on the MGF geology and geomorphology, as well as from the glacial deposits occurence and lithology. The ice sheet recession at the right bank of the middle Dnieper and within the Pripyat drainage basin took place by means of areal deglaciation, with pronounced sectoral-zonal pattern.
