云南易门狮子山铜矿床围岩蚀变岩相与矿石组构特征研究
Research on the Characteristics of Wall Rock Alteration and Ore Fabric of Shizishan Copper Deposit, Yimeng, Yunnan
摘要
Abstract
Shizishan copper deposit,Yimeng,Yunnan is one of the typical sedimentary-reformed copper deposit in Kunyang rift valley.The Cu mineralization at the deep part of the deposit is relative to wall rock alteration,the carbonation has close relations with Cu mineralization.The ores in siliceous dolomite type copper ore body are mainly of vein structure,disseminated structure; the ribbon ore is mainly of layer structure.The mineral particle in dolomite type copper ore is finer,which is bornite and copper pyrites; the mineral particle in slate type copper ore is coarser,which is copper pyrites and pyrite.The chemical composition of ore has the features of high Si,Ca and Mg,the important prospecting area is the contact zone of Luoxue and Etouchang formations.关键词
