摘要

The middle part of the northern continental shelf-slope region lies in the south of the Pearl River Basin. As an important structure unit of the northern continental margin of the South China Sea, it has experienced multiphase tectonic events and bears a thinned crust, upon which Cenozoic rifted-depressions with great hydrocarbon potential are developed. Several seismic profiles crossing the study area are introduced in this paper. Based on the interpretations and balanced cross-section restorations of these profiles, combined with structural geology, a Cenozoic tectono-sedimentary model is established. The results show that three stages can be proposed for this region: the rift stage from Paleocene to Eocene, the rift-depression stage from Oligocene to the Early Miocene, and the depression stage after the Middle Miocene.
