摘要
栗树街铜多金属矿矿体呈脉状、透镜体状,主要赋存于断层构造破碎带中,矿体围岩均为三叠系上统小定西组富钾的中基性火山岩,区域上该火山岩系为重要的含铜多金属矿赋矿层位。矿床受构造控制明显,蚀变矿化类型有黄铁矿化、硅化、碳酸盐化、褐铁矿化、绿泥石化、绿帘石化等。
The ore body of Lishujie Cu multimetallic deposit is veined, lenticular, mainly in the fracture zone. The wall rock of ore body is Upper Triassic Xiaodingxi Formation K-rich intermediate-basic volcanic rock. Regionally, The important Cu-bearing multimetallic deposit horizon is the volcanic rock series. The ore deposit is controlled clear by the structure. The metallogenesis alterations are pyritization, silicification, carbonatization, li- monitization chloritization epidotization etc.
