云南会泽铅锌矿地质特征及研究现状

Geological characteristics and research status of Huize Lead zinc mine, Yunnan Province

会泽铅锌矿为川-滇-黔成矿省中一大型矿床,具有负责的矿床成因特征。矿区出露地层主要为前寒武纪基底及沉积盖层;构造特征以断裂为主,呈NW向;出露岩浆岩为峨眉山玄武岩;Pb-Zn矿体主要受NW向断裂控制。同位素特征显示,矿床形成于晚三叠,成矿物质主要来自于沉积盖层,成矿流体主要为变质流体。

Located in the SYG(Sichuan-Yunnan-Guizhou)metallogenic province,the Huize is a large Pb-Zn deposit with complex mineralization process.Precambrian basement and sedimentary rocks are occurred at this deposit,and the main structures are the NW-trending faults.The Emeishan basalt is the only discovered magmatic rocks of the deposit.Isotopic data reveal that mineralization materials came from the sedimentary rocks and the ore-forming fluids were originated from the metamorphism.The deposition of the Pb-Zn elements was likely occurred at late Triassic.
