摘要
大姚县秀水河金铜矿矿体呈似层状、脉状,均赋存于断层构造破碎带中。目前发现的金矿为氧化矿,铜矿为硫化矿,两者的含矿岩石为褐铁矿化、硅化之构造角砾岩。属断裂构造控制的蚀变热液型金铜矿,特殊的构造破碎带部位及褐铁矿化。
The ore body of Xiushuihe Au-Cu deposit in Dayao is stratoid, veined in the fracture zone. The discovered Au ore is oxide ; Cu ore is sulfide. The ore-bearing rocks of them are the limonitized, silicified struc-tural breccias. It is a altered hydrothermal Au-Cu deposit controlled by the fault. The direct prospecting criteria are the special fracture zone place and limonitized, silicified zone.
