摘　　要：白水河金矿具多因素控矿特征,新元古界澜沧群勐井山组钠质变质岩为其主要矿源层,矿体产于北西向断裂破碎带中,金矿化与石英斑岩、煌斑岩脉侵入关系密切:强烈的黄铁绢英岩化、褐铁矿化及硅化,以及褐红、褐黄、紫红色的风化土是寻找金矿的明显标志;该区具有较大的找矿潜力。Abatract： Baishuihe Au deposit is characterized by the polynary ore control. The main ore source bed is Neoproterozoic Lancang Group Mengjingshan Formation sodic metamorphic rock. The ore body is in the NW fault fracture zone. The Au metallogenesis is in close relation to the quartz porphyry, lamprophyre vein intrusion. The intense pyrite sericitolitization, limonitization, brown-red, brown-yellow, purple-red weathering soil are the obvious prospecting criteria of Au deposit. The prospecting potentially is good in this area. Key Words： Magmatism; Structure Fracture Zone; Composite Ore Control; Baishuihe, Shuangjiang, Yunnan
