摘要
白云凹陷北坡具有独特的层序地层样式 :它的坡度较缓 ,不存在地貌上的陆架坡折 ,但由于断裂的活动 ,断层上下盘的落差客观上起到了陆架坡折的作用 ,使其低水位体系域具有Ⅰ型陡坡层序的特征 ,主要由盆底扇、深切河谷及充填物等组成。对于这种新的层序地层样式 。
The north slope of Baiyun Depression possesses a special sequence stratigraphic model.Its stratigraphic gradient is lower and has no shelf break.Fault activities make the throw of fault acting as shelf break,and cause its lowstand system trace to have the characteristics of type 1 sequence of steep slope.The slope consists maimly of basin fan,incised valley and fillings.This new sequence stratigraphic style is called fault controlled type 1 gentle slope sequence.
