| 摘 要： | 位于新疆富蕴县境内的希勒库都克铜钼矿属于斑岩型矿床。含矿花岗斑岩和石英闪长岩为弱过铝质高钾钙碱性岩石，具有相对富集大离子亲石元素、亏损Nb、Ta、Ti元素的地球化学特征。获得含矿花岗斑岩SIMS锆石Ｕ-Pb年龄（329.6±4.1）Ma。综合分析，花岗斑岩和石英闪长岩可能为同一岩浆不同演化阶段的产物。据含矿岩石高的正εNd（t）值、低的87Sr/86Sr初始值推测，其原始岩浆起源于亏损地幔源区。

| Abstract: | The Xilekuduke Cu-Mo deposit in Fuyun County, Xinjiang is a porphyry type Cu-Mo deposit. The ore-bearing granite porphyry and quartz diorite belong to weak peraluminous high-K calc-alkaline series, with relative enrichment in LILE and depletion in Nb, Ta and Ti. The SIMS zircon U-Pb age of 329.6±4.1Ma for ore-bearing granite porphyry is obtained. And the comprehensive analysis shows that both of granite porphyry and quartz diorite are products of the same magma in different magmatic evolution stage. The high positive ε_(Nd)(t)values and low initial ~(87)Sr/~(86)Sr values of ore-bearing rocks can be an evidence that its original magma came from depleted mantle. |
