摘要
磁法在内蒙古巴彦淖尔地区的磁性矿产勘查中,在原有小比例尺航磁勘查筛选的异常区域基础上开展大比例尺的高精度磁测工作,进一步确定找矿靶区,经过钻探验证磁性矿产为铁矿化镁铁质麻粒岩,在深度上与物探反演解释基本吻合。
In order to identify ore prospecting target areas further,magnetic method has been adopted in magnetic mineral exploration in Bayannur area of Inner Mongoliacarry,including high-precision magnetic survey carried on the basis of the abnormal areas distinguished and selected through small scale aerial magnetic survey.Drilling test indicates that the magnetic minerals are iron-mineralized mafic granulite that is basically matched to the geophysical inversion interpretation at depth.
