土壤磁学性质及其数值指标,有磁化率(K或X)、磁导率(μ)等等。土壤磁化率是土壤中各种反磁质物质(如水、高岭石、石英、硬石膏等)、顺磁质物质(如蒙脱石、伊利石、蛭石、白云石及各种矿物盐类)和铁磁质物质(磁铁矿、磁亦铁矿)的磁化率的代数和。而铁磁性矿物的磁化率要比其它成分的磁化率高几个数量级,虽然它们的含量不到1％,但决定着土壤磁性的大小。土壤成土母质、成土条件、成土过程、熟化程度及各种理化因素和生物因素,影响着土壤中含铁矿物的形态和转化、改变着土壤的磁性,因此和磁化率有一定关系。
Soil magnetism and its numerical indicators, the magnetic susceptibility (K or X), permeability (μ) and so on. Soil magnetic susceptibility is the soil of a variety of antimagnetic material (such as water, kaolinite, quartz, anhydrite, etc.), paramagnetic material (such as montmorillonite, illite, vermiculite, dolomite and various mineral salts ) And the ferromagnetic material (magnetite, magnetite) the algebraic sum of magnetic susceptibility. The magnetic susceptibility of ferromagnetic minerals than other components of the magnetic susceptibility several orders of magnitude, although their content of less than 1%, but determines the size of the soil magnetism. Soil soil parent material, soil forming conditions, soil formation process, the degree of maturation and a variety of physical and chemical factors and biological factors affect the shape and transformation of iron-bearing minerals in the soil, changing the soil magnetism, and magnetic susceptibility has a certain relationship .
