摘　　要： 内蒙古中东部大地构造位置处于内蒙古兴安地槽褶皱系东乌珠穆沁旗早华力西地槽褶皱带柴达木复背斜北东端东南翼。本文通过对该区域地层、岩浆岩、构造及地表矿化等现象的分析,认为铋铜矿体赋存在印支期二长花岗岩中北东15°—45°和北西向断裂构造中倾向北西和北东倾角较缓25°—45°。勘查区发现的矽卡岩带局部含方铅矿、闪锌矿体。属贫矿Pb+Zn小于5%。矿石自然类型属石英脉型黄铜矿、辉铋矿矿石铅锌矿属矽卡岩型矿石。 Eastern Inner Mongolia tectonic location is in the Inner Mongolia Xingan geosyncline Dongwuzhumuqinqi early Variscan geosyncline fold belt at the eastern end of the North Qaidam brachyanticline Southeast wing.Based on the analysis of the regional stratigraphy,structure,magmatite and mineralization of surface phenomena,that bismuth copper ore bodies occur in Indosinian granite in North East two-15 degrees and 45 degrees north west trending faults in North West and North East inclined angle is 25 degrees,45 degrees of corrosion.The skarn zone found in the exploration area contains galena and zinc blende ore bodies.A poor Pb＋Zn is less than 5%.The natural types of ore are quartz vein type chalcopyrite,bismuth ore and lead zinc ore belong to skarn ore.
