| 摘 要： | 希勒库都克钼铜矿床位于新疆北部富蕴县境内,萨尔布拉克-阿克塔斯断裂南侧.初步研究和钻孔资料表明,矿体受斑岩体控制,矿石具细脉浸染状、稀疏浸染状构造,金属矿物主要为辉钼矿、黄铁矿、黄铜矿、白铁矿、磁铁矿.岩体和其接触带内常见硅化、绿帘石化,次为绢云母化、钾化、绿泥石化、矽卡岩化,外围褐铁矿化,未见明显蚀变分带.含矿岩石地球化学研究表明,花岗斑岩、花岗闪长岩(花岗闪长斑岩)、闪长玢岩属弱铝质不饱和高钾钙碱性岩石系列,微量元素分布模式总体趋势一致,表明为同源岩浆演化产物.结合年代学研究成果认为,成岩成矿可能为同一岩浆作用过程.对矿区浅部地层中含辉钼矿石英脉包裹体氢、氧同位素研究成果显示,成矿流体中具来自天水部分流体特征. |

| Abstract: | Xilekuduke is located in Fuyun country of north xinjiang and the south fracture of Sharbulale-Aketasi.Preliminary studies and drilling data indicate that the ore body is controlled by porphyry.The ore has veinlet-like infection,sparse disseminated structure,metallic mineral resources are mainly molybdenite,pyrite,chalcopyrite,marcasite and magnetite.The most common is quartz,epidotization,followed by sericite,potassium mineralization,chloritization,skarn in the ore body and its contact belts,outside is the limonite,no significant alteration zoning.Geochemical studies of the ore-bearing rock shows that graniteporphyry,granodiorite(granodiorite porphyry),diorite belongs to weak aluminum unsaturated K calc-alkaline rock series,Trace element distribution pattern consistent with the overall trend,indicating that the same source magma evolution.With the mine’s year study shows that ore-forming may be the same magma process.The study with inclusion of hydrogen and oxygen isotope which come from molybdenite quartz vein in shallow stratum show the characteristics that ore-forming fluids is come from part fluids of air water. |
