昆阳群的因民组,其下限是穿时的,由以升降运动为主的东川运动所决定。东川运动存在着不均一性,表现在因民组下限的接触关系存在着局部整合、假整合、不整合。假整合比较普遍,而断层接触是后来构造迭加的产物。至今尚未见到使之因民组(含上覆地层)逆冲上来造成层位倒置的区域性之大断层。昆阳群依据东川运动和满银沟运动所致的接触面,划分为三个亚群,分别可与北方的长 Kunyang group due to the people group, the lower limit is worn, by the Dongchuan movement dominated by movements. There is a heterogeneity in the Dongchuan movement, manifested in partial integration, false integration and unconformity due to the contact relationship of the lower limit of the Mogao group. Fake integration is more common, and fault contact is the product of the superposition later. To date, no major fault has been seen in the area that caused the inversion of horizon due to the popularization of the Mogu Formation (including the overburden). Kunyang group based on the contact surface of the Dongchuan movement and Manyin groove movement, divided into three subgroups, respectively, with the northern long
