摘　　要：白水河金矿属断裂构造控制的热液蚀变型金矿床,金矿体产于新元古界澜沧群变质岩区多期断裂的次级分支断裂破碎带内。沿构造带有辉绿岩脉、石英斑岩脉、煌斑岩脉侵入,首次在临沧地区新元古界澜沧群变质岩区找到金矿。The Baishuihe Au deposit belongs to the Au deposit of Hydrothermal Alteration type controlled by the fault.The Au ore body is in the subordinate branch fault fracture zone of multiperiodic fault in Neoproterozoic Lancang Group metamorphic rocks.There are the intrusive diabase,quartz porphyry and lamprophyre veins in the structure zone.It is the first Au deposit discovered in Neoproterozoic Lancang Group metamorphic rocks in Lincang area.
