以1：5000比例尺进行地面磁法测量，采用廊坊物探大队研究所生产的电子垂直磁力仪，读取垂直磁场ΔZ。在此基础上，根据磁铁矿赋存于斑杂状斜长角闪岩中，二者都具有磁性的特点，进行间接找矿。同时，对比分析已知铁矿体磁场特征，建立磁铁矿地质-地球物理找矿模型，进行找矿预测。进而在重点区段实施初步工程验证，见矿率高，从而说明了地面磁法测量找寻磁铁矿的可行性和有效性。

Using electronic vertical magnetometer produced by research institute of Langfang geophysical brigade, the authors do the ground magnetic survey with 1:5 000 scale, read the vertical magnetic ifeldΔZ. According to the magnetite occurs in taxitic amphibolite, both have magnetic characteristics, indirect prospecting. At the same time, we analyze comparatively magnetic characteristics of known iron ore bodies, establish geological geophysical prospecting model of magnetic iron ore, proceed the prospecting prediction. And then we carry out the preliminary test at the emphasis section, gain high ore occurrence rate, which shows the feasibility and availability of ground magnetic survey for seeking magnetite.
