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 completed Bayannur-Baotou 1: 50000 Aero-Aeromagnetic and navigation data of Inner Mongolia, the aeromagnetic anomaly characteristics of the known medium- and medium-permeability intrusive rocks and the exposed Bayan Orogenic magnetic layer are compared with those of the exposed Permian Based on the characteristics of the granite rocks and sediments, 53 pieces of concealed rock or concealed magnetic bodies are delineated in the Mesozoic-Cenozoic area in combination with geological, physical and geochemical data. Among them, 45 pieces of hidden rock mass are inferred by aeromagnetic data, 6 pieces of hidden magnetic layer are inferred, 1 piece of inferred volcanic rock area is inferred, and 1 piece of hidden rock mass is deduced by using navigation data. It enriches regional geological information and provides reference for finding hidden and blind mines in the coverage area.
