U-Pb and Rb-Sr Dating of Granitoids from the Tatibin Group in the Plutonic Belt of Central Sikhote Alin

摘要

Magmatism in the central and southeastern Sikhote Alin is represented by plutonic and volcanic rocks of different development stages and geodynamic settings related to opposite movements of the Asian continent and Pacific Plate: frontal compression and lateral sliding. Frontal compression produced a plutonic belt concordant to folding. The next stage was marked by lateral sliding along the Central Sikhote Alin (CSA) and Eastern faults in the form of sinistral strike-slip faults. This was accompanied by the formation of a conjugate shear system with extended continental volcanoplu-tonic belts: Okhotsk-Chukotka, East Sikhote Alin, Pusan, and Southeast Chinese.
