昆仑河地区位于东昆仑成矿带西段，其矿产勘查工作还刚刚起步。本文在对昆仑河地区钨锡成矿规律梳理的基础上，对赋矿花岗岩体的岩石地球化学特征进行了分析，结果表明该岩体属于钙碱性过铝质侵入岩，具同碰撞花岗岩的特点。根据其岩石地球化学以及昆仑河地区的钨锡成矿特征，认为该花岗岩体即为该区钨锡矿的成矿母岩，形成于早泥盆世巴颜喀拉地块与东昆仑块体的碰撞阶段。结合现有找矿成果认为该区钨锡矿产找矿潜力较大。

Kunlun River area is located in the western part of the East Kunlun metallogenic belt ,its mineral exploration work has just started .In this paper ,tungsten‐tin mineralization law of the Kunlun River region is summarized ,geochronology and geochemistry of the ore‐bearing granite are analyzed ,the results show the ganite has the age of (396 .8 ± 4 .0 ) Ma ,which belongs to peraluminous calc‐alkaline ,syn‐collisional intrusive rocks .According to geochronology ,geochemistry characteristics of the granite and tungsten‐tin mineralization features in Kunlun River region ,that the Early Devonian granite plays essential part for tungsten and tin mineralization ,probably due to the collision of Bayan Har block and East Kunlun block .Combined with the results of exploration works in area ,we believe a great prospecting potential for tungsten tin mineral .
