摘要
磁铁矿矿石与强磁性火山岩磁性有明显的差别,前者以感应磁化为主,后者以剩余磁化为主。推荐一种利用地磁场变化磁场确定磁异常源磁性特征的方法,评论了几种涉及由剩余磁化引起的磁异常的解释方法。
The distinct difference of magnetic properties between magnetite ores and strongly magnetic volcanic rocks lies in the fact that magnetite ores mainly have induced magnetization,while strongly magnetic volcanic rocks are dominated by remanent magnetization.A method that could allow the remote determination of in-situ magnetic properties of sources by using natural geomagnetic variations has been recommended in this paper.Comments are also made on several methods related to interpreting magnetic anomalies caused by remanent magnetization.
