摘　　要：黄土覆盖区存在高强度的磁异常,地质解释是由磁铁矿引起。但4勘探线剖面施工的4个钻孔均未见到磁铁矿体,通过对三分量磁测井的研究,找到了65.12 m的磁铁矿、8.51 m金矿体和2.2 m铜矿体。说明三分量磁测井在寻找盲矿体中具有重要的指导意义。There are high intensity magnetic anomalies in the loess overlay area.Geological interpretation is caused by magnetite.However,the magnetite ore bodies are not found in four boreholes of the fourth exploration line profile,based on the study of three component magnetic logging,65.12m magnetite,8.51m gold orebody and2.2m copper orebody have been found.It shows that the three component magnelog has important guiding significance in the search for blind orebody.
