摘　　要：南沙海域新生代发生的多次构造运动既是盆地形成的主要原因,也是控制局部构造形成和发育的主要成因。本文以南沙海域曾母盆地典型构造为研究目标,分析了局部构造的沉降剥蚀史,进一步了解了前陆盆地局部构造沉降的特点,以及在区域动力场背景上局部构造的演化特征。在研究中采用构造高点和相邻凹陷模拟井的单井沉降史对比的方法,分析了局部构造在沉降过程中的各阶段主导因素。There are several construct movements at the southern part of South China Sea that are the main reason of basin formation and Local Structures forming and developing. The studying goal of this article is keystone local structures in the west of Zengmu Basin. The writ- ers analyze the history of subsiding-erosion about local structures, find out the subsiding charac- teristic of local structures on foreland basins, and realize their evolution feature. Contrast method of subsiding history of single well at the top of local structures and adjoining depression is adapted to research the subsiding dominant factors of each stage at the course of studying.
