| 摘 要： | 通过构造格架和层序地层格架的分析，结合区域不整合对比，将南堡凹陷地层与中国东部其他盆地进行对比，进行大型构造幕的确定，确认南堡凹陷古近系地层为区域可对比的裂陷Ⅲ幕和裂陷Ⅳ幕沉积。在此基础上，应用区域不整合规模的对比和火山活动期次研究，将南堡凹陷古近纪沉降划分为4个构造幕，并对各个构造幕的构造活动特征及其控制的沉积充填特征进行了分析。南堡凹陷的幕式构造活动可以分为三个阶段:在第一个阶段（即裂陷Ⅰ幕、裂陷Ⅱ幕），完全受到边界断裂活动的控制；在第二阶段（即裂陷Ⅲ幕），高柳断层开始活动，在南堡凹陷东部地区形成了陡坡断阶坡折带控制着沉积发育；而在第三阶段（即裂陷Ⅳ幕），高柳断层发育为控边断裂并控制着其下降盘的沉积充填。

| Abstract: | Through analyzing tectonic framework and sequence stratigraphic framework, comparing regional uniform surfaces, Nanpu Sag was compared with other basins in the eastern China, it was sured that strata of Paleogene of Nanpu Sag were related with sedimentary in the third period and fourth period of rifting. On the basis of all of these, it could be divided into 4 sub periodic subsidence through comparing the scale of uniform of different periodic rifting and volcanic activity periods researching. Meanwhile, characteristics of tectonic activity in different periodic rifting and their controlling on sedimentary filling were studied. Periodic rifting activity in Nanpu Sag could be classified into three periods. Sedimentation process was entirely controlled by boundary fault in the first and second period, sedimentary and subsidence were controlled by stepped shaped slope belt in steep slope of the eastern Nanpu Sag in the third period, while Gao liu fault became marginal fault and controlled sedimentary filling in its downing wall in the fourth period. |
