对萨吾尔金矿带中阔尔真阔腊金矿床和布尔克斯岱金矿床黄铁矿流体包裹体氦、氩同位素进行了测定和研究,两个金矿床成矿流体中3He/4He分别为0.64~4.25和1.16~9.48Ra,40Ar/36Ar分别为282~359和312~525;两个矿床成矿流体来源一致,主要来自岛弧深部的地幔(包括俯冲作用带来的洋壳及其上的沉积物),在地壳浅部又有大气降水的进一步稀释,是幔源流体和少量大气降水的混合物.两个矿床成矿流体演化规律一致,从成矿早阶段到晚阶段,成矿流体中大气降水/幔源流体比值逐渐增加.在此基础上结合矿床的地质、地球化学特征,认为两个矿床成因相同,是同一火山机构中形成的火山晚期热液型金矿床.
The isotopes of helium and argon in the fluid inclusions of the Central Kuerzhenkuola gold deposit and the Burkeside Dai gold deposit in the Uyghur gold belt were measured and studied. 3He / 4He in the ore-forming fluids of the two gold deposits With the 40Ar / 36Ar being 282-359 and 312-525, respectively. The origins of the ore-forming fluids of the two deposits are mainly from the mantle of the deep arc of the island arc (including the oceanic crust brought by the subduction and its On the sediments), further dilution in the shallow crust and atmospheric precipitation is a mixture of mantle source fluid and a small amount of precipitation.The evolution of ore-forming fluids of the two deposits is consistent, from the early stage to the late stage of mineralization, mineralization Based on the geological and geochemical characteristics of the deposit, it is considered that the two deposits have the same genesis and are the volcano late hydrothermal gold deposits formed in the same volcanic unit.
