地面高精度磁测在四川某磁铁矿勘查中的应用研究

摘要

高精度磁测法是磁铁矿勘查中常用且效果较好的一类方法.在利用地面质子磁力仪(WCZ-1型)对四川西部某磁铁矿普查区进行了大比例尺、高精度磁法测量后,进行系统的磁测资料处理与整理,对地质、物探、科研资料进行综合研究,进行找矿预测.进而在重点区布置精测磁测剖面,并进行带地形反演,为钻探工程提供了地球物理依据.实施初步工程验证,见矿率高,从而说明了地面高精度磁法测量找寻磁铁矿的可行性和有效性.%High precision magnetic measuring method is a kind of method often used wildly in iron ore exploration. In the use of the ground proton magnetometer (WCZ-1 type) large-scale, high-precision magnetic survey a magnetite census district in western Sichuan, Magnetic survey data processing and collation. Do a comprehensive study of geological, geophysical exploration, scientific data, and prospect prediction. Preliminary engineering validation further implementation in key segments, refer a high rate of mine. Illustrate the ground high-precision magnetic method used in magnetite survey is feasible and effective.
