磁法勘探在寻找玄武岩盖层下铁矿的应用

Application of magnetic exploration in search of iron under the basalt cover

长期以来在吉林地区人们一直期盼着在火山岩分布区及玄武岩盖层下寻找铁矿床,但一直没有先例。本文重点介绍了利用地面磁测方法在玄武岩盖层下寻找铁矿床的勘探实例,从而填补了在吉林地区利用磁法勘探寻找玄武岩盖层下铁矿的空白。

For a long time in Jilin area,people have been looking forward to seeking for the iron ore deposits under the volcanic rock distribution area and the basalt under cover,but it has been without precedent.This article focuses on the using of ground magnetic survey method to seek for the iron deposits under the basalt level,which has filled the blank of using the magnetic exploration of iron ore under the basalt cover.
