摘　　要：内蒙古高尔旗铅锌银矿区地处阿巴嘎旗北部。通过开展1∶50 000和1∶10 000比例尺的土壤测量,逐步确定了异常的范围和矿体的大致产状,通过异常的元素组合特征确定找矿的主攻矿种为铅锌银矿;进一步实施的激电中梯测量工作,确定了铅锌银矿体的深部延展状况,并确定了3条主要矿体;继而采用可控源音频大地电磁测深方法,发现了地表玄武岩覆盖层以下的隐伏铅锌银多金属矿体,经过地质工程验证,铅锌矿的规模达中型以上。工作证实,综合物化探方法对发现和圈定铅锌银矿体起到了重要作用。The Pb-Zn-Ag property in Gaoer Banner is in the north of Abaga Banner. The extent of anomly and ore body occurrence are gradually defined by soil geochemical survey at scale 1 ： 50000 and 1 ： 10000. Element association of the anomly shows that ore deposit here should be targeted to Pb--Zn--Ag deposits. Ore body occurrence at depth is determined by IP Mid gradient survey and blind ore bodies under basalt cover are shown by CSAMT sounding survey and drilling encounters the ore bodies which constitute a deposit larger than a medium size Pb-Zn-Ag deposit. Prospecting practice proves that the integrated geo- physical and geochemical techniques play an important role in delineating the Pb-Zn-Ag ore bodies.
