山西口泉断裂与大同侏罗纪煤田的关系

山西口泉断裂是一条规模大，活动期长的大断裂，它构成了云岗断坳与桑干河新裂陷的构造单元界限，同时又是大同侏罗纪煤田的东部边界，一般认为，这一大型基底断裂的形成和演化对煤田地质构造的发育具有重要的控制作用。本文对这一构造的形成机制和演化历史进行了分析研究，阐述了口泉断裂的青磁窑断层对大同侏罗纪煤田地质构造的展布规律和构造特征的控制关系。

Studies on the Relationship Between Kouquan Fault and Datong Jurassic Coal Field

Kouquan fault zone is a large-scaled geological structure with a long history of Yungangfaulted-depression and Sanggan River rift, and also a boundary on the east of Datong Jurassiccoal field. It has been thought that the formation and evolution of the large-scaled basementstructure should play an important role for the development and distribution of the structurein Datong coal field. In this paper,the forming mechanism and evolution history of theKouquan fault zone are analysed; and their control and influence on the geological structurein Datong Jurssic coal field are discussed.
