| 摘 要： | 通过对希勒库都克钼铜矿床的矿床地质、矿区地层、岩浆岩微量元素含量特征进行研究,认为下石炭统南明水组上亚组地层富集成矿元素,为矿区的主要含矿层位,该地层中强蚀变砂岩、凝灰质粉砂岩的成矿元素含量较高,为矿区的主要赋矿围岩。岩浆岩中成矿元素及主要伴生元素的含量特征显示,海西中晚期侵入的花岗闪长岩、花岗闪长斑岩和闪长斑岩（玢岩）与成矿作用密切,可能直接或间接提供了成矿物质来源。矿床在水平和垂直方向上均具有良好的分带特征,水平上由矿床中心向外呈现Mo、Cu（Au）、→V、Ti、Co、Cr、Ni、Mn、As、Sb、Hg、W、Sn、Bi→Ag、Zn、B、F的分带特征,垂向上自上而下呈现F、B、As（Cr、Ni）→Au、Cu、W（Mo、V、Co、Bi）→Mn（Au、V、Bi、Mo）的分带特征,对指导找矿具有一定意义。

| Abstract: | Based on a study of geological features and characteristics of trace elements in the strata and magmatic rocks of the Xilekuduke Mo-Cu deposit in Fuyun County,the authors consider that the lower subformation of the Lower Carboniferous Nanmingshui Formation is the main ore-bearing horizon,in which the strongly altered sandstone and tuffaceous siltstone are enriched with metallogenic elements.The content characteristics of metallogenic elements and associated elements in the magmatic rocks show that the late Hercynian granodiorite,granodiorite porphyry and diorite porphyry were closely related to the mineralization and might have provided metallogenic materials directly or indirectly.Studies of geochemical anomalies show that in the horizontal direction,the ore deposit has elemental zonation of Mo,Cu(Au)→V,Ti,Co,Cr,Ni,Mn,As,Sb,Hg,W,Sn,Bi→Ag,Zn,B,F,while in the vertical direction,the elemental zonation is F,B,As(Cr,Ni)→Au,Cu,W(Mo,V,Co,Bi)→Mn(Au,V,Bi,Mo),which may have some guiding significance for mineral exploration. |
