【摘要】 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。更多还原

【Abstract】 The occurrence,development and evolvement of the interformational slip structure in coal measures formation of Long Tan Zu in southern Jiangsu have been roughly undergone three stages I the interformational slip structure,the tightening thrust and the extending fall.The interformational slip structure occurs between compe tent and incompetent beds, and the cataclasites and granulitic rocks may be formed. The further development of the interformatio-nal slip structure will lead to the tightening thrust, and the pudding stones and mylonites con be formed. But this dynamo-metamorphic degree is stronger than the preceding stage.The ezten-ding fall results from the transformation of mechanical nature of compressive fault, and the dynamo-metamorphic rocks which are produced on the preceding two stages are destroyed. There is no donbt that this research, of the interformational slip structure in coal measures formation of upper permian seros in southern Jiangsu is of great importance for the exploration and the exploitation of coal field.更多还原
