| 摘 要： | 通过详细的光、薄片研究，认为乌兰乌珠尔铜矿主要金属矿物有黄铁矿、黄铜矿、磁铁矿、磁黄铁矿、毒砂、闪锌矿、黑钨矿和锡石等.进一步通过金属矿物组合及其成分分析和流体包裹研究，推断乌兰乌珠尔铜矿的金属矿物主要是在高硫逸度较还原环境下形成的，其形成作用可划分为锡石-多金属和黄铜矿-多金属两个成矿阶段.结合乌兰乌珠尔区域地质和矿床地质的研究，确定该矿床为中高温热液Cu矿床.

| Abstract: | A detailed research on polished sections and thin sections shows that the major minerals of Wulan Wuzhuer copper deposit are pyrite,chalcopyrite,magnetite,pyrrhotite,arsenopyrite,sphalerite,wolframite,cassiterite and so on.According to analysis of metallic mineral assemblage,compositions and fluid inclusions,it is concluded that the metallic minerals were mainly formed in a high sulfur fugacity and reduced environment.The ore deposit underwent cassiterite-polymetal and chalcopyrite-polymetal metallogenic stages.Combining the study of regional and orefield geology,the deposit is considered to be of meso-hydrothermal copper type. |
