摘要
磁法勘探是利用岩矿石的磁性特征来进行地质勘探的一种地球物理方法,是应用地球物理最古老的物探方法。通过观测和分析由岩石、矿石(或其他探测对象)磁性差异所引起的磁异常,进而研究地质构造和矿产资源(或其他探测对象)的分布规律。在针对磁测数据的整理和处理中,我们常采用空间域和频率域若干常用的数据处理方法,如化极、延拓、一二阶导数等各类位场转换处理,以更好的解译磁异常的存在和原因。
Magnetic prospecting method is a kind of geophysical method that uses the magnetic characteristics of the rock to carry out geological exploration. Magnetic anomalies caused by the magnetic properties of rocks, ores （or other objects） were observed and analyzed to study the distribution of geological structure and mineral resources （or other objects）. We often use spatial and frequency methods to deal with the magnetic data to better interpret the existence and causes of magnetic anomalies.
