| Summary: | The object of the study is the microelene composition of soils under the mountain meadow vegetation of the Western Caucasus in the Arkhyz area. The work uses traditional methodological techniques for studying the microelentic composition of the soils of mining regions: field soil and geochemical studies, cameral processing of materials and analytical generalizations. It was established that the formation of the microelene composition of soils under the mountain-meadow vegetation in the highland zone of Arkhyz is determined by the special conditions inherent in this part of the Western Caucasus: a high level of solar insolation throughout the year, increased moisture and a large number of incoming organic residues in the soil. Chelating organomineral complexes, Fe and Mn oxides and hydroxides, the products of aluminosilicata in the form of hydrospree, chlorites, and minerals of kaolinitis acts as phase and lumber soils of the region. The predominant binding with chelat organomineral complexes is characteristic of Zn and Cu, which have a high affinity to organic matter in an acidic environment. Consolidation on Fe and Mn oxides and hydroxides, clay minerals is characteristic of almost all microelements under consideration to varying degrees, depending on the gradation of strength of the formed connections. Based on the results of the study, we can conclude that the manifestations of the natural features of the development of the soil cover of the studied territory are strengthened by the role of chelating organomineral complexes in the binding of microelements in the soils and weakening of the influence of primary minerals products on the distribution of metals according to soil profile. The main zones of the accumulation of microelements in mountainmeadow soils are intracrene geochemical barriers-biogeochemical, sorption and alphahumus. The anthropogenic effect on the soil cover of the high-mountain landscapes of Arkhyz is locally pronounced and is not significantly reflected on the microelene composition of soils. |
