摘　　要：云南玉龙县玉湖金矿矿体呈透镜状、似层状赋存于北北东向压扭性断层构造破碎带中,北北东向断裂是该矿区的成矿和控矿构造;矿体围岩为二叠系玄武岩,区域上频繁而强烈的华力西期海底火山活动及海盆的大幅度沉降,为金矿的形成提供了丰富的物质来源。该金矿属热液型金矿床,具有较好的成矿条件和找矿远景.The orebody of Yuhu Au deposit in Yulong,Yunnan is lenticular,stratoid in NNE pressure shear fault fracture zone.The structure of metallogenesis and ore control is NNE fault in this orefield.The wall rock of orebody is P basalt.The regional frequent and intense Variscan submarine volcanism and sinking of sea basin in big dimension provide the abundant material source,metallogenesis condition and prospecting potentiality for this hydrothermal Au deposit.
