摘　　要：青海省尕林格铁多金属矿区第四系覆盖层近200 m.矿床以铁矿为主,铜、钴、铅锌多金属矿伴生,进行磁法勘探是最直接而有效的方法.通过对尕林格Ⅱ矿段的地面磁测资料分析,采用二度半反演方法,发现深部存在磁性体.经井中三分量磁测资料的处理和分析,为钻孔布设提供依据,指导钻探施工,在深部找矿方面取得了良好的地质效果.The Quaternary overburden in Galinge iron polymetallic orefield in Qinghai Province is nearly 200 m.The deposit is dominated by iron ore,associated with polymetallic ores such as copper,cobalt,lead and zinc.Magnetic prospecting is the most direct and effective method.Based on the analysis of ground magnetic survey data,the magnetic bodies are found in deep part with the 2.5-D inversion modeling.The processing and analysis of the borehole three-component magnetic survey data provide a basis for borehole layout and a guide for drilling construction.Good geological results have been achieved in deep prospecting.
