Destruction and destructive topography (summing up the recent geomorphological researches in Mongolia)

Abstract

Destructive topography is presented in Mongolia with Gobi peneplain (due to denudation) and large intermountain depressions due to tectonics. Concepts of exogenous (denudational) and endogenous (tectonic) destruction are introduced; the former proceeds together with the matter desintegration and landforms demolishion while the latter does not involve a desintegration of the substance and only changes landforms appearance. An importance of the concepts for geomorphological analysis is emphasized.
