The Region of Matching of Central-Asian Mobile Belt and Pacific Mobile Belt
Abstract: Central Asian and Pacific mobile belts are the two geological superstructures of Eastern Asia. They keep many geological secrets. There is a region of the interaction of the structures in the frames of the margin ofEast Asia. The region is ambiguous. It is denominated in tectonic superposition or covering (interference) of the segments of the structures. The main goal of the research work is to establish the boundary line of the jointing of two superstructures. Here we show the role of the Mesozoic tectonic restructuring and magmatism in the interaction of the structures. The region of their jointing is the boundary line between Bureja-Jziamusy and Badzhal terrains. The boundary line in the frames of Mongol-Okhotsk orogenic belt is disputable. Geochronological and paleomagnetic data and chemical composition of the volcano-plutonic rocks of the eastern margin of Mongol-Okhotsk belt and of the structures of Central-Asian mobile belt were recently obtained. The data allow us to review the region of the joint of the two structures of easternAsia. It was suggested to draw the boundary line of the joint (in this case-interference) of Central Asian mobile belt and Pacific mobile belt in the frames of the eastern margin of Mongol-Okhotsk orogenic belt along the margin of the disappearance of late Mesozoic oversubductional volcano-plutonic complexes in the western direction. The structure of Bureja-Jziamusy superterrain was related to the structures of the Pacific mobile belt. The proposed model of the region of jointing of two East Asian superstructures enables us to reconsider the tectonic and geodynamical and metallogeny schemes of evolution of the Eastern margin ofAsia.
