云南省维西县大宝山铜矿矿床地质特征及控矿因素初探

Study on the Geological Characteristics and Ore Controlling Factors of Dabaoshan Copper Deposits in Weixi County,Yunnan

云南省维西县大宝山铜矿位于金沙江构造带与蓝坪盆地结合部位,分布于区域性叶枝断裂和四十驮断裂组成的断夹块中。经对该矿床以往地质资料的综合整理,通过对矿区地层岩性、矿体产出形态、矿石特征、围岩蚀变等特征的总结,分析区内铜矿床的成矿控矿因素,以期对矿床今后的地质找矿工作起一定的指导作用。

Dabaoshan copper deposits is located at the junction of the Jinsha River structural belt and the LanPing Basin, distributed in the regional faulted blocks between Yezhi Fault and Sishituo Fault. On the basis of the comprehensive study of the existing geological data of the deposit, the paper concludes the formation lithology of the mining area, ore body output form, Ore characterisfics and wall rock alteration etc., and analyzes ore-controlling factors of the copper deposits in the area, in order to play a guiding role in ore prospecting in the future.
