摘要

摘要: 南黄海盆地奠基于前南华纪变质基底之上,盆地演化历经南华纪-早、中三叠世海相地层发育期、晚白垩世-古近纪箕状断陷发育期和新近纪-第四纪坳陷发育期,为一典型地台-断陷-坳陷多层结构的复合盆地。受不同时期地质营力及区域应力场变化的影响,南黄海盆地形成多种构造样式,可分为伸展构造、挤压构造、反转构造和底辟构造4类,前3类构造样式是地壳水平运动的结果,后一类是地壳垂直运动的结果。

Abstract: The South Yellow Sea Basin, based on the pre-Nanhua metamorphic basement of the Lower Yangtze platform, is a polycycle basin with a sandwich-type construction. The geologic evolution of the basin can be divided into three stages:the Nanhua-early and middle Triassic marine basin stage, the late Cretaceous-Paleogene graben fault basin stage and the Neogene-Quaternary depression basin stage. There are various tectonic styles controlled by multiple-period tectonic reformation and different regional stress fields. On the new seismic profiles, we can recognize four kinds of tectonic styles (extension structure, compression structure, inversion structure and diapir structure). The first three structures are due to hori-zontal motion of the crust and the last is due to vertical motion of the crust.
