Crustal types of Central and Northeast Asia, Far Eastern and Arctic continent–ocean transition ares
The article presents results of generalization of deep seismic studies performed in Central and Northeast Asia, as well as in the Far Eastern and Arctic continent–ocean transition areas. Variations in the crustal types for various tectonic structures of this area have been analyzed. A sketch map of crustal type distribution in the structures of Central and Northeast Asia and the continent-ocean transition area have been compiled. Studying different crustal types and patterns of heir distribution over the area, depending on types of geological structures, is of interest for understanding the history of formation and transformation of the Earth’s crust as a whole. The map reflects patterns of spatial distribution of various crustal types in Central and Northeast Asia and can serve as a basis for substantiating global geotectonic models of the formation of Eurasia and its interaction with the Pacific Ocean.
