摘　　要：万古金矿位于位于平江县城西南。金矿（化）体产于中元古宙蓟县系变质岩中,严格受NWW向构造破碎带控制。金矿体呈似层状、透镜状。矿脉由含金石英脉和（或）含金破碎蚀带组成。流体包裹体研究表明,成矿流体温度较低（220~260℃）,具有多源性,并以深源流体为主。Wangu gold deposit is located in the Pingjiang county,Hunan province.The mineralization was controlled by structural fracture zone,and emplaced in Middle Mesoproterozoic Jixianian System metamorphic rocks.The ore bodies are stratiform-like and lenticular composed of the gold-bearing quartz veins and cataclastic alteration zones.Fluid inclusion data of Wangu gold deposit show that the ore-forming fluid was characterized by low temperature（220 ~ 260℃）.The ore-forming fluid was derived from various sources and mainly from the deep fluid.
