摘要

东南地区中新生代形成的盆岭构造,受控于盆岭区内业已存在的大型断裂系统,盆岭区内存在有北北东至北东向、近东西向、近北西向等3组主要断裂系统。根据区内盆地特征,可划分为地堑型盆地、铲状断层型盆地和变换-伸展型盆地3类。东南地区的盆岭构造总的面貌呈现南北纵向分块,东西横向分带之特征。形成中国东南地区盆岭构造的外部条件是滨西太平洋域的地球动力学演变,次要条件是西侧印度板块向北移动与欧亚大陆的碰撞及推挤。

Abstract

Basin and range structure developed during the Meso-Cenozoic period in Southeast China was controlled by those pre-existed fault systems.There are three fault systems in the area with NNE-NE, nearly E-W, NW strikes.Based on the characteristics of the basins, there are three types of basins in the area: graben, listric faults and transform-extension.The characteristics of the basin and range province in Southeast China is shown by longitudinal blocks in S-N and cross zones in E-W.Formation of basin and range province in Southeast China was mainly resulted from geodynamic evolution of west marginal-Pacific tectonic domain, and from collision and squeezing of Indian plate with Euro-Asian continent.
