摘要
黄金洞金矿位于湖南省平江县黄金乡。金矿（化）体赋存于蓟县纪浅变质板岩及变质砂岩中,同时受控于断裂构造。金矿体呈脉状、透镜状、扁豆状产于断裂带扩容地段。流体包裹体资料确定的成矿流体性质为中温（成矿温度下限为336~339℃）、中低盐度〔w（Na-Cl）eq〈10.98%〕的变质热液。金的沉淀与温度降低和成矿流体的混合作用有关。
Huangjindong gold deposit is located in Pingjiang county,Hunan province.The mineralization was controlled by faulted structure,and emplaced in Jixianian period slate and sandstone.The ore bodies are vein-like and lenticular formed at the expansion space of the fault zone.Fluid inclusion data of the Huangjindong gold deposit show that the metamorphic fluid was characterized by low temperature（higher than 336 ~ 339 ℃）,and relatively low salinities（w（NaCl） eq 10.98%）.Gold precipitation was caused by cooling and mixing of the different source fluids.
