| 摘 要： | 珠斯楞铜金矿位于晚古生代板块缝合部位,产于华力西晚期花岗斑岩和闪长玢岩岩脉中,通过矿区基础地质、物化探等的研究,确定有2个矿体、1个矿化体。主要矿石矿物为黄铜矿、黄铁矿、磁黄铁矿、闪锌矿、方铅矿、毒砂等,呈浸染状、细脉状分布。化探垂直分带性表明,Au和前缘晕元素在浅部富集,Cu在中深部富集。矿床为斑岩型,主要发育青磐岩化带,其可作为区域上大型斑岩铜矿的找矿标志。

| Abstract: | The Zhusileng Cu-Au deposit is located in a Late Paleozoic plate suture zone related to granite porphyry and dioritic-porphyrite. Two orebodies and one metallizd body were found through regional geological, geophysical and geochemical prospecting in mine field. Ore minerals, mainly including chalcopyrite, pyrite, pyrrhotine, sphalerite, galena and arsenopytite, distribute in gangue miners as disseminated sulfides or in the form of veins. Geochemical vertical zonation indicates that Au enrichs at shallow part and Cu in the deeper level. Propylitization is the main type of mineralization alteration related to Hercynian volcanism and magmatic intrusions and can be made as an indicator of large-sized porphyry type Cu deposits in the study region. |
