西南格陵兰前寒武纪Tartoq群中,金出现在毒砂—黄铁矿、砷黝铜矿和黄铜矿三种共生组合中。在玄武质成分的绿岩中含金硫化物矿化似呈整合的石英层,透镜体和脉体。在毒砂—黄铁矿中,金微粒细度大约为990。在富砷黝铜矿脉中细度大约为720,在黄铜矿石英脉中细度大约为500,毒砂—黄铁矿层为海底喷发成因,而砷黝铜矿和黄铜矿石英脉及透镜体为成岩的和/或变质成因。
In the Precambrian Tartoq group in Southwestern Greenland, gold appears in three symbiotic combinations of arsenopyrite - pyrite, arsenic tetrahedrite and chalcopyrite. Gold mineralization in the greenstone of basaltic composition appears to be an integrated quartz layer, lens, and veins. In arsenopyrite-pyrite, the fineness of gold particles is about 990. The fineness of the arsenic-rich tetrahedrite vein is about 720, the fineness of the quartz vein in the chalcopyrite is about 500, the arsenopyrite-pyrite layer is the origin of the seabed eruption, and the arsenic-tetracrite and chalcopyrite vein And the lens body is diagenetic and / or metamorphic.
