新疆叶城库喀阿孜铅锌(-铜-钨)矿的成矿背景及矿床地球化学研究

本项目主要通过对新疆叶城库喀阿孜铅-锌-（铜-钨）矿床系统的地质地球化学研究，探讨该区变火山岩及侵入岩的来源、形成时代、及其与成矿作用的关系、成矿的地球动力学背景，探讨三种不同类型矿体（铅-锌-磁铁矿块状硫化物似层状矿体、铜（-铅-锌-钨）矿体和铅-锌-磁铁矿-石榴石-辉石组合的矿体）的矿床地球化学特征、成矿时代、成矿过程、矿床成矿模式，明确该类矿床的矿床地质地球化学找矿标志，并通过对西昆仑地区元古代地层中的一些块状硫化物矿床（点）的对比研究，建立适合本地区成矿特点的找矿模型，为成矿预测服务。

Based on the systematical geological and gochemical research on the Kukaazi Pb-Zn-(Cu-W) deposit, Yecheng, Xinjiang, to discuss the oirgin and diagenetic ages of meta volcanic rocks and intrusive rocks in the deposit area, and their relationship to the metallogenesis, and the dynamic background of metallogeny,to discuss the geochamicamical characteristics, ore-forming ages, ore-forming process, and metallogenic models of three types of orebodies (layered lead-zinc-magnetite massive sulfide orebody, Cu-(Zn-Pb-W) orebody, and Pb-Zn-magnetite-garnet-diopside orebody), to identify the geological and geochemical prospecting parameters and to establish prospecting modles of this type of deposit in the west Kunlun area through comparative metallogeny, and to serve the mineral exploration.
