| 摘 要： | 阿尕泽铜金矿位于青海省共和盆地的最南缘，大地构造位置处于秦岭一昆仑东西构造北亚带边缘及北北西向（河西系）构造带交接部位。成矿带属于鄂拉山成矿体系。矿区属于高寒草甸区，采用土壤样测量反映测区被覆盖的地质信息。通过土壤地球化学测量圈出的元素异常及形态，确定成矿主元素Au、As、Sb的浓集中心，根据金矿前缘指示元素As、Sb的形态建立找矿靶区AⅠ、AⅡ、AⅢ、AⅣ，确定铜金矿的成矿类型为构造热液蚀变型金矿。对总结鄂拉山地区金矿成矿规律具有指导意义。

| Abstract: | Agaze copper-gold deposit is located hai province, of which the tectonic position be in the south margin of Gonghe Basin in Qingtectonic belt edge and NW （Hexi series） tectonic longs to the Ela Shan mineralization system and ngs to the belt trans Qinling Mountains-North Kunlun fer area. The metallogenic belt be the mineralization is located in alpine meadow area. Measuring soil samples show covered geological information of measurement zone and using element anomalies and shape from soil geochemical measurements determine the concentration center of the ore-forming elements Au, As, Sb. According to the leading edge indicator elements for gold As, Sb the ore-prospecting target AⅠ. AⅡ. AⅢ. AⅣ and the copper-gold deposit belongs to tectonic hydrothermal alteration type gold deposit, showing a guiding significance for gold mineralization in Ela Shan area |
