1) recessive sand ridges
衰退沙脊
1.
The sand ridges on Stratum U2 are recessive sand ridges,which have belonged to the TST since the LGM(last glacial maximum),and their upper bounding surfaces are the MFS of the LGM.
基于高分辨率的单道地震和多波束测深数据,识别并对比了东海陆架中部同一海区相距20余万年的层U14和层U2两期沙脊群,其中层U14期沙脊属于埋藏沙脊,位于东海海底以下90 m深处,推测属于距今320~200 ka的海侵体系域(TST),沙脊顶界面是该期海侵的最大洪泛面(MFS);层U2期沙脊位于东海陆架,属于衰退沙脊,系末次盛冰期(LGM)以来的TST,顶界面是LGM以来的MFS。
