摘　　要：　内蒙油房—二把伙地区位于华北地台北缘南兴安晚华力西期地槽褶皱带,中生代火山岩系发育,燕山期中酸性岩浆活动强烈,形成了一系列火山、潜火山热液型银多金属矿床。文章论述了二把火银矿、油房银多金属矿的矿床地质特征及其控矿因素、找矿标志,认为该区具有可观的找矿潜力,并提出了找矿方向。Youfangxi-Erbahuo area is situated in Late Hercynian Nanxingan geosynclinal fold belt and developed with Mesozoic volcanics, strong Yanshanian intermediate-acid magmatism and a series of volcanic-subvocanic hydrothermal Ag polymetal ore deposits. The paper describes typical Erbahuo Ag deposit and Youfangxi Ag-polymetal deposit geology, ore-control factors and marks showing the potetial and direction for further exploration.
