Morphostructures of zones of contact between orogenes and depressions at the Northern Tien Shan

Abstract

The authors analyzed geology and geomorphology of the morphostructures in several transitional regions 'from ridge to depression and concluded that large and complex morphostructural bands marked the transition. The data given on the morphostructures of the transition zone of epiplatformian orogenes suggest the morphostructures to be of widespread type. Origin and special features of the zone are controlled by deep faults, Transition «ridge-depression» zones are linear, they are characterized by a network of active faults, differentiated mosaic tectonic pattern, variety of geological structure, complex character of topography and wide spectrum of exogenous processes.
