摘　　要：云县果园铜矿区位于澜沧江火山弧与兰坪-思茅弧后盆地过渡带,铜矿体呈脉状赋存于上三叠统小定西组(T_(3)xd)安山玄武岩、安山岩分布区北西向断层构造破碎带内。断层构造破碎带明显控制了铜矿体的展布,成因类型为构造控制的热液脉状铜床。Guoyuan Cu orefield in Yunxian,Yunnan is in the transitional area between Lancangjiang volcanic arc and Lanping-Simao back-arc basin.The Cu orebody is veined in NW fault fracture zone of Upper Triassic Xiaodingxi Formation(T_(3)xd)andesitic basalt,andesite area.The extension of Cu orebody is controlled clear by the fault fracture zone.It is a hydrothermal veined orebody in genesis of Cu deposit.
