摘　　要：文章通过对内蒙古翁牛特旗二把伙银多金属矿区地质特征综合分析,认为矿区成矿作用类型为与火山穹窿构造形成有关的隐爆角砾岩成矿,成矿作用受断裂构造和火山机构双重控制;从浅表至深部,矿床类型依次为浅成低温热液型、裂隙充填隐爆角砾岩型和斑岩型(隐爆角砾岩筒型)。为二把伙银多金属矿区深部找矿提供了理论依据。Based on the comprehensive analysis of geological features of the silver polymetallic deposit of Erbahuo,Wengniuteqi,Neimongu,this article considers that the ore-forming type is belonged to hidden breccia mineralization with the volcanic dome formation.The mineralization is dually controlled by the fault structure and volcanic structure.From the superficial to deep,there are epithermal type,fracture filling hidden breccia type and porphyry type,hidden breccia tube type,deposits in series.This provides a theoretical basis for deep prospecting in Ag polymetallic ore of Erbahuo.
