摘　　要：拟在总结前人有关东海与南海盆地形成机制研究的基础上,整析两盆地的差异构造演化及其形成动力机制,选取盆地内部典型富生烃凹陷进行构造演化分析,依照盆地的构造演化进程,着重对比了各凹陷聚煤前基底构造、聚煤期伸展方式、断坳转化与聚煤后构造改造特征,旨在揭示两盆地构造控煤规律。Based on the previous research of formation mechanics of the east China sea and the northern south China sea,integrated the different tectonic evolution of this two basins under different dynamic mechanics.In accordance with the tectonic evolution sequence of typical rich hydrocarbon generation sags,the coal-accumulating features were comparatively analyzed with the three perspectives of the basement structure before the coal accumulating,the extensional structure and the rift and depression transformation in the period of the coal accumulating and the tectonics reworking after the coal accumulating.
