摘要:
六梅金矿床位于广西贵港市大平天山岩体东北部,矿体赋存于寒武系黄洞口组细碎屑岩中,受高角度断裂构造的控制。根据矿物组合与脉体的切割关系,将矿床热液活动过程划分为4个阶段:石英—黄铁矿阶段(Ⅰ),黄铁矿—毒砂—石英阶段(Ⅱ),方铅矿—闪锌矿—黄铜矿—(砷)黝铜矿—铁白云石—石英阶段(Ⅲ),石英—铁白云石阶段(Ⅳ),其中Ⅱ阶段为主要的成矿阶段。载金矿物主要为毒砂和(砷)黄铁矿,EPMA分析结果显示金主要以“不可见”的次显微—超次显微包体金形式存在。流体包裹体测试结果表明:石英或方解石中的包裹体以气液两相为主,主成矿阶段温度平均为181 ℃,平均盐度[w(NaCl)]为9.36%,密度为0.946 g/cm3,显示成矿流体为低温、低盐度、低密度流体。H、O同位素组成(δD值介于-73‰~-57‰之间,
