摘要
///Abundant oblique slip faults characteristic of the torsion structures occur in the Tertiary cap rocks of the Huanghua depression. The torsion structures in the depression comprise two types: translational structures and rotation-torsion structures. The former appear in the areas bounded by the Cangdong fault, Xuxi fault, Nanpibei-Yanshan concealed fault and Zaopo-Guxian concealed fault. The latter appear dominantly in the Wumaying region in the southern part of the Nanpibei-Yanshan concealed faults, and secondly in the Shenusi region on the downthrown side of the Cangdong fault. The tenso-shear fault systems may exercise an important control on the formation of traps and faulted zones, vertical migration of hydrocarbons, and different controls on hydrocarbon accumulation.
