西双山铜多金属矿区域地质背景及成矿条件分析

Analysis on Regional Geological Background and Metallogenic Condition of Xishuangshan Copper Polymetallic Deposits

西双山铜多金属矿区位于八家子-杨家杖子成矿带的小孤山-影壁山断裂的西南部。区内断裂发育,脉岩众多,蚀变强烈,以往的工作中,在火山岩内、火山岩与花岗岩的接触部已发现了铜、铅锌、钼的矿(化)体。本文通过对区内地质特征进行分析,预测其找矿潜力。

Xishuangshan copper multi-metal mining area is located in the southwest of xiaogushan - yin- bishan fracture zone which is a part of Bajiazi-Yangjiazhangzi metallogenic belt. In this area, the fault is development, the dike is multitudinous and the alteration of rocks is intensive. In the previous work, the mineralized body of Cu Pb-Zn Mo have been discovered in the volcanic rock and the contact zone of vol- canic rock and granite. This article analyzes the geological characteristics and predicts its prospecting po- tential in this area.
