摘　　要：根据新完成的内蒙古巴彦淖尔-包头1∶5万航磁、航放资料,对比已知中基性侵入岩和出露的白云鄂博群磁性层的航磁异常特征,以及出露的二叠纪花岗岩航放特征,结合地质、物性和化探等资料,在中新生代覆盖区共圈定隐伏岩体或隐伏磁性体53片。其中利用航磁资料推断隐伏岩体45片,推断隐伏磁性层位6片,推断隐伏火山岩区1片;利用航放资料推断隐伏岩体1片。丰富了区域地质信息,为在覆盖区寻找隐伏矿、盲矿提供参考。According to the newly obtained 1 ： 50000 aeromagnetic, airborne radioactive data ofBayan Nur--Bao tou area i^l Mongolia province, this paper made a comparative study on characteristics of magnetic anomalies to know inlermediate-basic intrusive rocks and exposed Bayun Obo Group magnetic layer, and the airborne radioactive characteristic of exposed Permian granitoids, combined with the geological and physical characters, geochemical data, to delineate 53 concealed rock or concealed magnetic body in Mesozoic-Cenozoic coverage area. The use of aeromagnetic data to infer 45 concealed rocks, inferred 6 concealed magnetic layers, and inferred I concealed volcanic rocks area： The use of airborne radioactive data to infer 1 concealed rock. So enrich the regional geological information, and provide reference to find concealed mines and blind ore in coverage area.
