The basic characteristics and geologic meanings of crustal structure in the domain of Japan Sea

LI Rui-lei,ZHAO Xue-ping,YANG Bao-jun (Department of Geophysics, Jilin University, Changchun 130026, China)  
Utilizing the multiple profiles from seismic sounding and other geophysical data completed in the domain of Japan Sea, the paper synthetically analyzes the characteristics of crustal structure and Benioff zone in the domain. The crustal structure of the domain of Japan Sea takes on the differences between continental crust and oceanic crust and two types of dichotomy and trisection. The Benioff zones have different dip in different directions and their extended depths have greater differences. The drive of Japan Sea's opening comes from multiple compression and extension stress field produced by the westword subduction of the Pacific plate.
