苏南龙潭煤系中层滑构造的发生、发展和演变大体经历了层间滑动、收缩逆冲和伸展错落三个阶段。层滑构造发生于骨干和非骨干岩层之间,形成碎裂岩和碎粒岩等。收缩逆冲是层间滑动进一步发育的结果,可形成磨砾岩和糜棱岩等,和前一阶段相比,动力变质程度较深。伸展错落是由压性断裂力学性质转化造成的,并破坏了前二阶段的动力变质岩。苏南地区晚二叠世地层的层滑构造研究对于煤田的勘探和开发是很有意义的。 The occurrence, development and evolution of middle-level slip structure of the Longtan coal measures in southern Jiangsu generally experienced three stages of interlayer sliding, shrinkage thrusting and spreading. The layer-slip structure occurs between the backbone and non-backbone rock formations, forming cataclasites and nodules. Shrinkage thrusting is the result of further development of interlaminar sliding and can form conglomerate and mylonite. Compared with the previous stage, the dynamic deterioration is deeper. The extensional patchwork is caused by the transformation of compressive fracture mechanics and destroys the former two stages of dynamic metamorphic rocks. The study of the stratigraphic slip in the Late Permian strata in the southern Jiangsu area is of great significance to the exploration and development of the coalfield.
