摘　　要：东昆仑地处中国中央造山带的西段,横跨青海、新疆两省(区),不仅是我国重要的金属成矿带,也是我国新的黑色有色金属资源基地。该区构造-岩浆活动强烈,成矿地质条件优越,新近发现或扩储了一批大(中)型矿床。区内主攻矿种为钨、锡、金、铁、铜、镍、铅锌等;主攻矿床类型为岩浆熔离型铜镍硫化物矿、造山型金矿、云英岩-矽卡岩-热液脉型钨锡矿、矽卡岩-斑岩型铁铜铅锌多金属矿。本文在综合分析已有各类工作成果基础之上,划分了成矿谱系和矿床成矿系列,开展了资源潜力评价分析,提出了4个一般远景区及4个普通远景区,为进一步找矿工作提供支撑。The East Kunlun metallogenic belt is located in the western section of the central orogenic belt in China,which goes through Qinghai and Xinjiang provinces.It is not only the important metallogenic zone but also an important nonferrous metal base in China.This area underwent several intensive tectonic and magmatic activities and has favorable metallogenic conditions.Several large-or medium-scale ore deposits were discovered,which are enriched inW,Sn Au,Fe,Cu Ni,Pb and Zn.The main deposit types are magmatic melting-type Cu-Ni sulphate deposit,orogenic type Au deposits,greisen-skarn hydrothermal Sn deposit,and skarn-porphry-type Fe-Cu-Pb polymetallic ore deposits.On the basis of comprehensive analysis of previous studies,this study classifies metallogenic lineage for the East Kunlun W-Sn-Au-Ni metallogenic belt and conducts the assessment of potential for mineral resources.Finally,four prospective areas and for average areas were defined,providing the support for the further prospecting.
