摘　　要：在综述东昆仑地区成矿地质背景及成矿条件的基础上,通过对肯德可克、驼路沟、督冷沟和大场等典型矿床的剖析,详细论述了矽卡岩型铁多金属矿、海相火山喷气沉积叠加后期改造型钴(金)矿、块状硫化物型铜钴矿和造山型金矿的成矿特征、成矿规律及找矿前景,并结合区域成矿模式、找矿模型和各类矿产、异常的空间分布特征确定出8个成矿远景区,13个找矿靶区。同时指出东昆仑各成矿带的成(找)矿潜力由大到小的依次排序为:昆南成矿带≈阿尼玛卿-北巴颜喀拉成矿带>昆北成矿带>>昆中成矿带。On the basis of comprehensive analyses on geological setting and mineralization conditions in the eastern Kunlun metallogenic belt, this study systematically discusses metallogenic characteristics, mineralization processes and prospecting potential for skarn iron and polymetallic deposit, hydrothermal superimposed Sedex type Co-Au deposit, massive sulfide Cu-Co deposit and orogenic Au deposit with the examples of Kendekeke, Tuolugou, Dulenggou and Dachang deposits, respectively. Eight metallogenic prospective regions and thirteen prospecting targets have been determined by a regional metallogenic model, spatial distribution of different ore deposits and anomalies in the eastern Kunlun area. Also, an order of increasing metallogenic potential for mineralization zones in the area has been inferred as follows： central Kunlun area, Northern Kunlun area, Aneymaqen-northern Bayankala area, southern Kunlun area.
