广西金秀龙围铜矿位于大瑶山多金属成矿带的东部,是石英脉型铜矿床;矿体呈脉状、部分呈透镜体状产于断裂破碎带内的下泥盆统(D1);矿化主要有黄铜矿化、黄铁矿化及辉铜矿化,矿石矿物主要为黄铜矿及辉铜矿。矿床中黄铁矿样品的Re-Os等时线年龄为449±140Ma,结合矿床地质特征,暗示该地区铜矿主要形成于加里东期,也暗示该地区加里东期之后没有明显的岩浆热液活动。 The Jinxiu Longwei Copper Mine in Guangxi is located in the east of the Dayao Mountain polymetallic metallogenic belt and is a quartz vein type copper deposit. The ore body is vein-shaped and is partly lenticular in the shape of a lens body in the Lower Devonian (D1) ; Mineralization is mainly chalcopyrite, pyrite mineralization and chalcocite mineralization, ore minerals are chalcopyrite and chalcocite. The Re-Os isochron age of the pyrite samples in the deposit is 449 ± 140Ma. Combined with the geological characteristics of the deposit, it indicates that the copper deposits in the area were mainly formed in the Caledonian period, suggesting that there is no obvious magmatic hydrothermal fluid in the area after the Caledonian period activity.
