Linear geological structures of the southern Aldan-Stanovoi shield and eastern Central-Asian Foldbelt: The geodynamic aspect

Abstract

Based on the digital models of the relief and gravity anomaly field, the linear geological structures have been analyzed within the test area (122–129°E, 52–60°N) at the junction between the Aldan-Stanovoi Shield and a fragment of the eastern part of the Central-Asian Foldbelt. The application of a special filter to the digital relief model and the further processing of the initial data with the WinLessa program allowed us to obtain new additional information on the structure of the considered area. As a result, the temporal succession in the development of the geodynamic processes at the Stanovoi and Mongol-Okhotsk system-forming fault zones was established from the Late Jurassic till the present time. An evolution model of the junction boundary was proposed for this territory.
