Mongolian-Siberian mountain belt and its analogues

Abstract

Belts of regenerated mountains including large arched uplifts, linear deformations and rift zones are widely distributed over Eurasia and North America. Mongolian-Siberian mountain belt is an example of such system.

Mountain belts of the Mongolian-Siberian type with complete set of zones are characterised with general arch-like uplifts of the socle due to isostatic upheavals above anomalous mantle lenses. Within isolated mountain belts individual forms replace each other across the belt. In the mountain belts associated with epigeosynclinal constructions the forms replace each other along the system's axis. «Uncomplete» mountain belts include only large arches and linear deformation zones and have no general socle uplifts.

Mountain belts of the Mongolian-Siberian type have their own elements of power supply in the deep structure, lateral movements of adjacent geoblocks influence the formation of their structure and act as an additional factor of the orogenesis.
