我们分析了最近获得的两条多道地震剖面，它们横跨危险地带和南中国海芦滩地区。构造沉陷重建表明，南部大陆边缘可划分为三个不同沉降速率的阶段。裂解后两个地区都存在构造沉降的延迟，这可能与海底扩张过程中的主要地幔对流有关，这种对流是由大陆边缘以下的次级地幔对流引发的，此外还与岩石圈厚度的变化有关。同时，不同走向的延缓沉降期也不同。在芦滩地区，这一阶段在32-23.8 Ma之间，而在危险地区，这一阶段要晚得多(19-15.5 Ma)。我们认为，南中国海的扩张性裂谷作用主导了这一延迟沉降速率阶段的变化。
We analyzed two recently acquired multi-channel seismic profiles across the Dangerous Grounds and the Reed Bank area in the South China Sea. Reconstruction of the tectonic subsidence shows that the southern continental margin can be divided into three stages with variable subsidence rate. A delay of tectonic subsidence existed in both areas after a break-up, which was likely related to the major mantle convection during seafloor spreading, that was triggered by the secondary mantle convection below the continental margin, in addition to the variation in lithospheric thickness. Meanwhile, the stage with delayed subsidence rate differed along strikes. In the Reed Bank area, this stage is between 32–23.8 Ma, while in the Dangerous Grounds, it was much later (between 19–15.5 Ma). We believe the propagated rifting in the South China Sea dominated the changes of this delayed subsidence rate stage.
