| 摘 要： | 文中根据地震、钻井资料,对黄骅坳陷孔南地区古近纪孔店组残留地层进行精细研究,获得了对孔店组沉积特征的深刻认识,进而分析孔店期沧东断层伸展作用和走滑作用对孔店组沉积的控制作用,并得出沧东断层在孔店期的构造活动规律:沧东断层在SQ1层序沉积时期开始发生伸展作用,SQ1层序沉积期和SQ2层序沉积期伸展强度较弱,并且只有沧东段活动;SQ3层序沉积期和SQ4层序沉积期伸展作用持续增强,并且整段都有活动,成为控制东侧下降盘沉积作用的边界断层。与此同时,沧东断层的右行走滑运动也控制了其东侧孔店组地层的沉积作用。

| Abstract: | According to the seismic and drilling data, this paper studies the residual formation of Paleocene Kongdian Formnation in Kongnan Area, Huanghua Depression and gains profound understanding about the sedimentary features of Kongdian Formation, then analyzes the control role of extension and strike-slip of Cangdong fault on Kongdian Formation deposition at Kongdian stage and drawsthe tectonic activity law of Cangdong fault at Kongdian stage, namely at SQ1 depositional stage, Cangdong fault shows the extension, which is very weak at SQ1 and SQ2 depositional stages and happens in Cangdong section only. The extension of the whole section is stronger and stronger at SQ3 and SQ4 depositional stages, and the Cangdong fault controls the deposition in the throw wall. At the same time, the strike-slip role of Cangdong fault controls the deposition of Kongdian Formation on the eastern side. |
