【摘要】 黄骅坳陷位于渤海湾盆地中部,在始新世孔店组开始接受沉积,主要发育在坳陷的南部地区,沿着沧东断裂带下降盘展布。根据区域性不整合,综合岩芯、地震、测井资料,将孔店组划分了一个二级层序和4个三级层序。叙述了各时期沉积地层的展布特征,分析了早期原型盆地结构特征,指出了构造活动对沉积的控制作用。更多还原

【Abstract】 Huanghua depression is in the middle area of Bohai bay basin,it deposits at the beginning of Kongdian formation,and distributes along the Cangdong fault zone.Based on regional unconfoimity surface,core,seismic and well log data,Kongdian formation can be divided into 1 second-order sequence and 4 third-order sequences.This paper discribes its distribution characteristics,and analyses former basin structure characteristics,and points that structure movement controlled deposition.更多还原
