摘　　要：沉积—火山岩建造中金矿是近年来在内蒙古白云鄂博地区新发现的具有较大远景的矿床类型。金矿产于中下奥陶统包尔汗图群布龙山组(O1-2b)、哈拉组(O1-2h)中,含矿岩系为一套海相沉积—火山岩建造,具层控特征。成因类型属于海相火山—沉积作用有关的沉积变质—改造型金矿。Under the tectonic background of the north margin of north china plate in baiyun＂ ebo area , Gold deposit occured in Sedimentary-volcanic formation is an important deposit which have prospective significance. Gold deposit were identified in bulongshan and hala information Baoerhantu group of middle-lower Ordovician. the ore-bearing rock series is a set of submarine volcanic-eruptive and exhalative-sedimentary formation, which is characterized by strata-bound deposits. The gold deposit is classified as a sedimentary-metamorphic reconstruction-type that have something to do with the submarine volcanic deposition.
