摘要
尕林格矿区第四系覆盖层较厚,约200 m.矿床以铁为主,共(伴)生有铜、钴、铅锌多金属矿床.地面高精度磁法测量和三分量磁测井是最为直接而有效的方法.通过对地面磁测和三分量资料的处理与分析来指导钻探施工,协助地质布孔,寻找井旁盲矿体取得了很好的效果,特别是井中三分量磁测起到了地面磁测所起不到的作用和效果.井中三分量已经成为寻找磁铁矿和磁性体共、伴生多金属矿的必不可少方法之一.
The Galinge orefield,containing iron with polymetallic deposits of copper,cobalt,lead and zinc,is covered by Quaternary overburden about 200 m thick.The most direct and effective exploration methods are ground high-precision magnetic survey and three-component magnetic logging.The combination of ground magnetic survey and three-component data processing and analysis is applied to guide the layout of geological drilling and find blind orebody,which has achieved good results.Particularly,the three-component magnetic survey is more effective than the ground method in some way.The three-component borehole has been one of the essential methods to find magnetite ore and magnetic associated polymetallic deposits.
