摘要
查啊母铜矿分布于属分布于班怒带西段五峰尖~拉热拉新火山岩浆弧,赋存于古~始新世美苏组火山岩,受北西向断裂构造控制,属中低温热液型矿床。矿(化)体呈脉状,具有膨涨缩小特征。主要金属矿物主要有黝铜矿、黄铜矿、孔雀石,铜矿石具它形~半自形粒状结构、碎裂斑状结构,呈浸染状构造、脉状构造。矿化蚀变主要有硅化、黄铁矿化、孔雀石化等。
The Zhaaimu copper deposit is located in the Wufengjian-Rajelaxin volcanic magma arc in the western segment of the Bannu belt.It occurs in the Meisu Formation volcanic of Paleo-Eocene,controlled by NW-trending faults and being a kind of medium-low temperature hydrothermal deposit.Its ore(mineralized)bodies are in veins and are characteristic of expansion and contraction.Its main metal minerals include tetrahedrite,chalcopyrite and malachite.The copper ore is of xenomorphic-hypidiomorphic-granular texture,cataclastic porphyry texture,disseminated structure and vein structure.Its mineralization and alteration mainly comprise silicification,pyritization,peacock petrifaction and etc.
