Geological Features and Prospecting Sign of Mojia Tin Deposit in Gejiu County Southeast Yunnan Province

滇东南地区是云南省重要的有色金属矿产资源基地,具有良好的成矿条件,该区处于个旧锡多金属矿成矿带西部和著名的个旧锡矿西区的西缘,具有良好的成矿环境。矿区内锡多金属矿化与印支燕山火山岩浆活动关系密切,受断裂控制明显。地层岩性、构造特征、化探异常及物探异常是该矿区的重要找矿标志。

Southeast Yunnan area is the important nonferrous metals mineral resources base in yunnan province,it has good metallogenic conditions.It’s located in the west of Gejiu tin polymetallic metallogenic belt and the west of the famous Gejiu tin,It has good metallogenic environment.Tin polymetallic mineralization in the mine with indosinian,yanshan epoch volcanic closely related to magmatic activities,obviously controlled by fracture.Formation lithology,tectonic characteris-tics,geochemical anomalies and geophysical anomalies are the important prospecting marks.
