Geomorphology of the Shakhunsky Uvals

Abstract

A large orographic unit - Shakhunsky Uvaly - is known in NE Gorki region, within the Vetluga drainage basin. By hypsometric position, relief and geology of the unit it can be considered as a series of remnants of planation surface, dominating at present the northern Privolzhskaya upland, earlier it spread further northward. The Vetluga region morphostructure reflects consequent stages of the structural-tectonic evolution. The Shakhunsky Uvaly is formed long before the Dnieper Ice Age. During the whole Cenozoic it controlled the spatial distribution of the morphosculptural elements, including pre-glacial, glacial and post-glacial forms.
