摘　　要：研究区位于东昆仑造山带东段伯喀里克-香日德印支期成矿带,区内物化探异常显示了较好的成矿前景。在异常查证过程中发现12条含钨矽卡岩带,圈定30个钨矿体;发现6条含金银构造蚀变带,圈定金矿体8个、金银矿体1个。通过分析表明:矿床受构造、岩浆岩、地层等多种因素控制,当碳酸盐沉积建造遇到高温流体后,发生了强烈的气水溶液交代作用,其成矿阶段主要为矽卡岩期进变质阶段、退变质阶段和氧化物阶段,石英-硫化物期分早期硫化物阶段和晚期硫化物阶段。The study area is located in Burkaric-Xiangride Indosinian Berkarik-Chantilly Indosinian period metallogenic belt in the eastern part of the East Kunlun orogenic belt,and the geophysical and geochemical anomalies in the area show a good metallogenic prospect.In the process of anomaly verification,six gold and silver bearing structural alteration belts were found,including 8 deposit ore bodies and 1 gold and silver ore body.According to the analysis,the minerals in the area were formed under the control of regional structure,magmatic rocks,strata and other comprehensive factors.When the carbonate sedimentary formation encountered high temperature fluid,strong gas-aqueous metasomatism occurred.The mineralization stages were mainly the progressive metamorphic stage,the retrometamorphic stage and the oxide stage,and the quartz-sulfide stage was divided into early sulfide stage and late sulfide stage.
