Morphostructural subdivision of the Turan Plain

Abstract

Special features of Turanian large morphostructures are discussed and morphostructural types are identified in accordance with the orographic units relation to the basement topography and sedimentary mantle structure, morphostructural regions of various direction are outlined, the orientation being controlled by structural frame of the plain. Inherited morphostructures prevail at the western part of the plain, while those of inverse type are widespread at the sort-hern and eastern periphery. The author came to a conclusion that the morphostructural plan was relatively simple as compared with the sedimentary mantle structure, at the central part of the plain a regional sub-longitudinal zone is revealed where sublatitudinal morphostructures come into contact.
