drape fold
1.The folds and faults develop very much in the basin,and the former can be di- vided into 3 genetic types——regional compressive fold,local associated fold and drape-like fold,and the latter mainly shows 3 directions——near EW—NE,NW and NNE,in which the near EW—NE and NNE faults are well-developed relatively and control the distribution framework and sedimentary features of uplift and depression.
2.7.It is indicated the prospects for exploration are BeiDagang bueried-hill-drape-lik fold oil accumulation belt,Baidong Structure belt and Chengbei fault step oil accumulation belt,which directs the explorations of Neogene in Qikou depression.
