imbricated fault meaning in English

叠瓦状断层

Kongxi buried hill shows following features in the seismic profiles : the structures are asymmetric . there is flexural syncline on the east side and a monocline on the west side . asymmetric repetition of stratigraphic units is present in the drill wells and the dips of beds and faults are gentle . the permo - carboniferous system of both sides almost lie in the same slope and the events of cambrian or upper proterozoic are continuous from east to west . the phenomenas suggest that kongxi buried hill could be a thrust belt been traced which consists of reverse faults . the imbricate faults mainly effect pre - jurassic strata . there are obvious angular unconformity between jurassic - cretaceous system and paleozoic involved deformation of thrust . the thrust front in some place has cut off the beds of jurassic - cretaceous system . the structural style of the thrust structure changes along the strike of the kongxi buried hill
地震和钻井资料揭露的孔西构造带前第三系潜山的地质特征可以归纳为：构造带总体上不对称构造带内部有地层重复现象石炭二叠系地层的位置明显高于两侧的同一地层的高度。用由34条向东倾斜的逆冲断层组成的叠瓦扇构造模式能够比较合理地解释上述地质特征。该带向东倾斜的逆冲叠瓦状断层组主要影响前侏罗系地层，侏罗白垩系与卷入逆冲构造变形的古生界地层之间有明显的角度不整合。
