摘　　要：江东湾锑金矿床位于雪峰造山带中段,产在区域主干断裂控制的断块上升隆起区。矿体呈脉状、薄板状赋存于新元古界板溪群五强溪组上段浅变质岩系中。通过矿床成矿地质特征、控矿因素、垂向分带、找矿前景等方面的综合分析,认为江东湾锑金矿床是湘西龙王江金矿集区最具有找矿潜力的矿床。矿床浅部以锑或锑金为主,深部以金为主,且越向深部,金矿化越强,隐伏矿脉增多,深部找矿空间大,具有中型金矿床的资源潜力。Jiangdongwan antimony-gold deposit is located in the middle section of Xuefeng orogenic belt,which is produced in the uplift area of the fault block controlled by the main regional fault.The ore bodies,in vein and thin-plate,are hosted at the upper part of the shallow metamorphic rock series of Wuqiangxi Formation of Neoproterozoic Banxi Group.On the basis of the analysis of the metallogenic and geological characteristics,ore-controlling factors,vertical zonation,and prospecting perspective of the deposit,it is considered that there is a great prospecting potential in Jiangdongwan antimony-gold deposit in Longwangjiang gold ore concentration area in West Hunan.The shallow part of the deposit is dominated by antimony or antimony-gold orebodies,and there are mainly gold orebodies in the deep part.The gold mineralization is stronger and stronger with the depth in the deposit,and the hidden ore veins increase as well.There is a large prospecting space in the deep for the resource potential of a medium-scale gold deposit.
