摘　　要：云南洱源县芹菜塘金矿矿体呈似层状赋存于断裂构造破碎带中,矿体围岩为下元古界石门关组二段(Pt1s2)大理岩、斜长角闪岩,从地表出露较多岩株推断,矿区中深部可能存在隐伏岩体.从石门关组分布区广泛发育的金、银、铜、铅等矿化及地球化学异常来看,预测该矿区具有较好的金多金属矿找矿前景.The orebody of Qincaitang Au deposit in Eryuan,Yunnan is stratoid in the fault fracture zone.The wall rock of orebody is Lower Proterzoic Shimenguan Formation Member 2(Pt1s2)marble,plagioclase am-phibolite.According to many stocks outcropping on surface,there is the good Au multimetallic prospecting po-tentiality in this orefield.
