　　In active rift basins,tectonism is extremely important for sequence stratigraphic pattern,affecting both the sequence architecture and internal makeup.Sequence stratigraphic framework of a Paleogene rift succession in Qiongdongnan basin,northern South China Sea were builded using seismic profiles,complented by well logs and cores.One first-order and three second-order sequences are identified on the basis of basin-scale unconformities.Constituent third-order sequences are defined by unconformities along the basin margins and correltative conformities within the central basin.
