Determination of Cenozoic tectonic movement in the northern South China Sea and the relationship between oil-gas reservoir and tectonic movement

CAI Zhou-rong1,2 LIU Wei-liang1,WAN Zhi-feng1,GUO Feng1 (1.Key Laboratory of Marginal Sea Geology,CAS,Guangzhou 510640,China; 2. Maritime Academy of Sun Yat-Sen University,Guangzhou 510006,China)  
The northern edge of the South China Sea is the most complicated one of the passive continental margins,and a number of complex tectonic movements have gone through in the Cenozoic. Several different programs about the division of tectonic movement were brought up by the predecessors,but still lack the scope of comprehensive study due to the restrictions of study area. Based on analysis of the existed division plan and taking into account the research results about the tectonic movement in shallow-water area,as well as combining with the latest research information in the deep sea district,the author proposed a new plan to divide tectonic movement in the Cenozoic in the northern South China Sea into four tectonic movements:Shenhu Movement at the end of Late Cretaceous,Zhuqiong Movement which began at the end of middle Eocene (including the first scene and the second scene),Nanhai Movement at the end of late Oligocene,and Dongsha Movement at the end of the middle Miocene in the east of the northern South China Sea.The four tectonic movements play an important role in controlling the hydrocarbons Source rocks,as well as the development of oil and gas migration and accumulation.
