| 摘 要： | 上海地区的断裂构造系统主要是由北东向、东西向和北西向三组主干断裂组成。三组主干断裂向东分别延入长江口和杭州湾海域,与海域主要断裂构造相连接。其中北东向断裂与北西向断裂形成时代不一,两者间无成生联系,晚新生代以来的活动性差异也甚大。

| Abstract: | The fracture tectonic system in Shanghai area is mainly formed by three groups of main fractures in north-east,east-west and north-west directions.The three groups of fracture, which extend eastward individually into the mouth of the Yangtze river and the sea area of Hangzhou Bay,have linked up with the main fractures in the sea area.Among them, the age of the formation of the fracture in the north-east direction is quite different from that in the north-west direction,and also there is no genetic relationship between them. Moreover,the variance of their activities has been great since Late Cenozoic era. |
