GEODYNAMIC EVOLUTION OF THE CENTRAL-ASIAN AND MONGOL-OKHOTSK FOLD BELTS AND FORMATION OF THE ENDOGENIC DEPOSITS

Abstract

This paper deals with the geodynamic evolution and some problems of metallogeny of the Central Asian and Mongol-Okhotsk fold belts. It has been established that throughout its history (from Proterozoic to Cenozoic) all known types of geodynamic settings existed. It has been found, that each setting has a strictly specified geodynamic structure, a number of tectonic structures, magmatic and metamorphic complexes and related mineral deposits. Each geodynamic setting has its own well-defined structural-magmatic and metallogenic zonation. Metallogenic analysis performed on the basis of paleogeodynamic reconstructions for short intervals suggests a position of the ancient borders of the litospheric plates. Magmatics and metallogenic activity was found along and around the boundaries of these plates. This analysis also suggests additional criteria for prediction and search for minerals within Transbaikalia and Mongolia.
