主　　题：Red River Fault South China Sea Southeastern margin of the Tibetan Plateau Junction of the Yinggehai and Qiongdongnan Basins 

摘      要：The Red River Fault,which originated from the southeastern margin of the Tibetan Plateau,has a great significance for obtaining a further understanding of the regional tectonics,topography and river catchment evolution,as well as the petroliferous sedimentary basin *** junction of the Yinggehai and Qiongdongnan Basins(YQB Junction)is the key to understanding when and how the strike-slip deformation on the South China Sea resulted from the collision between the Indian and Eurasian *** this study,we show regional seismic profiles,3D seismic and drilling core data to analyze the tectonostratigraphy in the YQB Junction,aiming to identify its tectonic framework and the associated faults system.A transitional domain from the strike-slip zone to the extensional deformation zone was mapped,which consisted of the No.1 Fault and the Zhongjian *** strike-slip faulting in the YQB Junction was active during the Oligocene-Early Miocene,with a period of strong faulting in the Early *** with the regional tectonic evolution,a coevolution model of strike-slip and extensional deformation in the YQB Junction and the adjacent area was *** the Eocene,the YQB Junction was controlled by the NW-SE extension and formed a series of distributed rifts bounded by the NE-striking faults and filled up with proximal *** the earliest Oligocene,a NW-trending strike-slip fault began to develop in the YQB Junction and crosscut the NEstriking normal *** the occurrence of the strike-slip faults,the NE-striking faults,to the west of the No.1 Fault and the Zhongjian Uplift,failed to ***,to the east of the No.1 Fault and the Zhongjian Uplift,the faulting continued to develop until the latest Late *** faulting of the NW-trending faults was observed to be active until the earliest Middle *** then,with the exception of some diapiric structures and associated small-scale faulting in the Yinggehai Basin,we did not observe
