MINERALOGICAL AND CHEMICAL FEATURES OF MAGNETIC PHASE OF SOILS OF SOUTH TAIGA OF PERMSKII KRAI
With a view to improving the system for monitoring soil farmland using methods of environmental magnetism the authors studied features of mineralogy and elemental composition of magnetic phase of soddy-podzolic soils in Southern Taiga's agrolandscapes of Perm Krai. By method of dry fractionation using permanent ferrite magnet, magnetic soil phase was selected from non-magnetic matrix of fine soil. Electron probe microanalysis of magnetic phase was made by the use of the analytical complex «TescanVegaII». Direct experiment determined cell chemical and mineralogical compositions of magnetic particle phase. It was found that magnetic minerals in soil phase are local inter-profile geochemical anomalies. The priority role of chromium, nickel, and zinc in the composition of impurity elements in the magnetic fraction of fine soil was established. Minerals of iron of high-temperature genesis are present in the magnetic phase of agrolandscape soils. The obtained data confirms the expediency of using the methods of ecological magnetism for improving monitoring of the soil cover of the agrolandscapes of the region.
