NATURAL-TECHNOGENIC GEOCHEMICAL ZONING OF THE PERM TERRITORY

Abstract

The paper resents a natural-technogenic geochemical zoning of the Perm Territory as developed by the author. Theregion has a developed mining industry, and the study of the spatial distribution of elements is of considerable theoretical and practicalinterest. In the course of the study, background contents were obtained that characterize the region’s natural geochemical background.Separately, the areas with a high degree of anthropogenic transformation of the natural environment were studied. As a result of thecluster analysis, natural-technogenic geochemical areas were identified, geochemical specialization was determined for all the areas,and an association of elements was identified: the Northern Urals of litho-sidero-chalcophile specialization with vanadium-zincpolymetallic association; Western Urals of litho-sidero-chalcophile specialization with vanadium-polymetallic association; Kizel coalbasin of sidero-chalco-lithophile specialization with cobalt-manganese-polymetallic association; Middle taiga of sidero-chalcophilespecialization with manganese-lead association; Southern taiga of litho-chalcophile specialization with strontium-zinc association;Verkhnekamskoye deposit of potash salts of sidero-litho-chalcophile specialization with cobalt-polymetallic association; Coniferousdeciduous forests of sidero-litho-chalcophile specialization with nickel-polymetallic association; Kungur forest-steppe of siderophilespecialization with cobalt-nickel association. The results obtained are relevant for the ecological and geochemical study of the territory.The author comes to a conclusion that it is necessary to locally study the geochemical characteristics of soils in the zone of oil production influence to ensure environmental safety in the associated territories. Of most relevance is research in karst areas and in wetlandcomplexes.
