摘要
左庄矿区位于平邑石膏矿区的中部,石膏矿赋存于古近纪官庄群卞桥组中段地层中,主要含矿4层,矿层呈层状、似层状展布。以石膏矿形成的地质背景为基础,对其矿石地质特征、矿床成因及找矿标志进行了系统分析,对在该区找寻同类型石膏矿具有一定指导意义。
Zuozhuang mining area is located in the middle part of Pingyi gypsum mining area.Gypsum ore occurs in the middle section of Bianqiao formation of Paleogene Guanzhuang group,which mainly contains 4 layers,and the ore bed is layered and stratoid.Based on the geological background of gypsum deposit formation,the ore geological characteristics,deposit genesis and prospecting criteria are systematically analyzed,which has a certain guiding significance for looking for the same type of gypsum deposit in this area.
