永顺-张家界地区矿山地质特征研究

Study on the geological features of mines in Yongshun Zhangjiajie area

保靖~慈利的矿体是扬子准地台与江南隆起两个构造单元的分界线,也是碳酸盐台地相区与台缘斜坡钙屑碳酸盐相区的分界线。该矿区矿体具有规模大、经历时间长、活动期多和开启性等特点,它控制着永顺-张家界地区自震旦纪-三叠纪的沉积和构造格局。对本地区矿山地质的聚集产生了不利的影响。

The geological change of Baojing to Cili is the dividing line between the two tectonic units of the Yangtze platform and the Jiangnan uplift, and also the boundary between the carbonate platform facies area and the calcium carbonate facies area of the platform margin slope. The geological change of the mine area is characterized by large scale, long time, active period and opening. It controls the sedimentary structure of Sinian and Triassic in Yongshun Zhangjiajie area. It has a negative influence on the mine geological agglomeration in this area.
