摘　　要：云南绿春县牛波金矿矿体呈脉状、透镜状赋存于北西-南东向脆韧性剪切断裂破碎带中、近矿围岩为下二叠统高井朝组(P_(1g))安山玄武岩、灰岩。属构造构造控的低温热液脉型金矿床,断裂破碎带是找金矿的重要标志,硅化、褐铁矿化(铁帽)、黄铁矿化、青盘岩化是矿区的直接找矿标志。The orebody of Niubo Au deposit in Luchun,Yunnan is veined,lenticular in NW-SE brittle-ductile shear fault fracture zone.The wall rock near orebody is Lower P Gaojingchao Formation(P_(1g))andesite basalt,limestone,belonging to low T hydrothermal veined Au deposit of ore control of structure.The fault fracture zone is the important prospecting criterion and silicification,limonitization(gossan),pyritization and propylitization are the direct prospecting criteria of orefield.
