摘　　要：新疆木祖克铅锌铜矿床位于新疆西天山博罗霍洛成矿带中西段,是金、铜、铅、锌、钼多金属的重要成矿区。矿区发现铅锌铜矿体8个,主要赋存于花岗闪长岩与上奥陶统呼独克达坂组大理岩接触带,含矿层延伸方向与矿区接触带产状基本一致。矿体呈脉状、透镜状产出,地表出露长度为15~250 m,厚度为0.35~4.51 m。样品分析结果显示,铅品位为0.56%~22.39%,锌品位为2.70%~19.35%,铜品位为0.42%~9.39%。地球物理异常主要以激电低-中阻异常为主,伴有磁异常。通过对矿床地质特征、地球物理特征等综合分析,认为木祖克铅锌铜矿床成因类型属矽卡岩型矿床。Muzuke lead-zinc-copper deposit is located at the middle-west section of Borohoro metallogenic belt in the West Tianshan Mountains of Xinjiang,which is an important metallogenic area of gold,copper,lead,zinc and molybdenum mineral resources.Eight lead-zinc-copper orebodies are found in the mining area,which are mainly hosted in the contact belt of granite diorite and marble of the Upper Ordovician Hudukdaban Formation.The extension direction of the ore-bearing strata is basically consistent with the occurrence of the contact belt in the mining area.The orebody is veined and lenticular,with the surface outcrop length of 15-250 m and thickness of 0.35-4.51 m.The sample analysis data show that the grade of lead is 0.56%-22.39%,the grade of zinc is 2.70%-19.35%,and the grade of copper is 0.42%-9.39%.The geophysical anomalies are mainly low-medium resistance anomalies of IP,accompanied with magnetic anomalies.Through the comprehensive analysis of the geological and geophysical characteristics of the deposit,it is considered that Muzuke lead-zinc-copper deposit belongs to skarn type deposit.
