摘　　要：云南巍山县扎村金矿矿体呈似层状、透镜状,赋存于近南北向推覆断裂F_(24)构造破碎带中,矿体近矿围岩均为具有碎裂岩化和角砾岩化构造碎屑岩;矿体的蚀变类型为石英-白云石-黄铁矿型;矿体中的金主要以单矿物自然金的形式存在;扎村金矿属构造破碎带控矿的中-低温混合热液型金矿床。The orebody of Zhacun village Au deposit in Weishan,Yunnan is stratoid,lenticular in nearly NS nappe fault F_(24) fracture zone.The wall rock near orebody is the fragmentated and brecciated rocks.The alteration of orebody is the quartz-dolomite-pyrite type.The Au oreis mainly the monomineralic natural Au.It is a middle-low T mixed hydrothermal Au dposit controlled by fracture zone.
