Spatial variations of the magnetic susceptibility in the profiles of paleocryomorphic soils

The distribution and variation of the magnetic susceptibility (MS) have been studied in the profiles of soils with paleocryogenic features. The MS values proved to be tightly related to the C_org content, the $pH_{H_2 O}$ (on the paleocryogenic microhighs (blocks)), and the pH_KCl (in the paleocryogenic microlows (interblock spaces)). The horizons of the buried soils were characterized by the high variability of the MS with the maximum variations at much smaller distances than those in the surface soils. This allows us to suppose that the soil-forming conditions in the ancient soils differed significantly from those in the recent soils. The differences in the spatial variability of the MS values are largely related to the presence of paleocryogenic features, which also considerably affect the current soil processes.
