Seshchin glaciodislocations and dynamic conditions of their formation

Abstract

Seshchin glaciodislocations situated at the boundary of Bryansk and Smolensk regions near Roslavl are related to the Middle Pleistocene push moraine ridges embracing gigantic preglacial trough. Different viewpoints indicated in literature are considered of the conditions of these glaciodislocations' formations.

A new hypothesis is suggested according to which detached masses are of scale structure. Glacial ploughing took place there in the course of continual detachment of bedrock masses. This hypothesis is confirmed both by concrete geologic- geomorphologic data and the results of theoretical studies in glaciology and geological engineering.
