General Regularities of the Distribution of Microelements in the Surface Deposits and Soils of West Siberia

Abstract
The effect of genesis, grain size distribution, mineral composition, physicochemical and chemical properties of soil-forming rocks, climate, relief, and soil formation on the bulk content of microelements, regularities of their spatial and profile distribution in the solids of West Siberia is considered. The revealed regularities correspond to the general laws governing the formation of lithologic and lithochemical composition of sediments, and associations of chemical elements in them. A connection of microelements in the surface sediments of the South-East of the West Siberian Plane with the Altai-Sayan fold region is confirmed. It is noted that aeolian sedimentation and exogenous processes in Holocene could level the granulometric and microelement composition of the upper layer of soils, reduce their genetic differences and connection with soil-forming rocks.
