当岩浆从中海脊下涌起的时候，岩浆中的磁铁矿物质按地磁场的方向被磁化。
As magma rises under the mid-ocean ridge, ferromagnetic minerals in the magma become magnetized in the direction of the magma become magnetized in the direction of the geomagnetic field.
由于磁性矿物受当时磁场作用往往呈定向排列，导致岩石磁化率各向异性，反映了岩石的磁组构特征。
The anisotropy of rock magnetic susceptibility, caused by the oriented arrangement of magnetic minerals effected by then magnetic field, reflects the feature of the rock magnetic fabric.
常用的磁性泥浆含有铁磁质或磁性物质，另外还有一些低磁化率矿物也有贡献，如赤铁矿、钛铁矿。
The most common magnetic muds contain iron filings or magnetite. Other paramagnetic minerals such as hematite and ilmenite may contribute, although their magnetic susceptibility is considerably less.
磁化率空间分布机理如下：首先，强烈的人为影响使土壤中磁性矿物人为来源占有重要地位。
The distribution mechanism of magnetic susceptibility as follows: first, magnetic minerals from human activity in soils play an important role;
