Abstract:Limited by the quality and distribution of exploration data,the south and north strata in the South China Sea have not been unified.Based on regional seismic sections covering the South China Sea,this paper uses the pluralism to synthesize a variety of data including magnetic data,and ocean drilling program (ODP) data to establish the stratigraphic framework in the South China Sea.The seismic geological strata calibration is carried out mainly based on the high exploration degree area (Zhujiangkou,Qiongdongnan,Zengmu,and Lile Basins),some other strata (in Beikang and Nanweixi Basins) are also calibrated.Six sets of seismic reflectors and their interfaces have been identified in the Cenozoic.According to our study,the Cenozoic strata in the South China Sea are controlled by the expansion.There are three sets of strata:pre-expansion stage,expansion stage and post-expansion stage.The research results provide significant references for the unification of the south and north strata,the partition of new schemes,and Moho surface research in South China Sea.
