SOIL FORMATION IN CONTACT ZONES OF TERRITORIAL AND AQUATIC COMPLEXES OF SHIRA STEPPE ^{[№ 12 ' 2017]}
Diverse soil formation conditions in Shira Steppe of Chulym-Yenisei basin in Minusinsk intermountain trough, with their dissected relief and a substantial amount of standing lakes provide for a great topsoil diversity in the area. This fact complicates the possibilities of their use and methods of protection. Subordinate positions receive additional inflow of water and substances, additionally reinforced by erosion processes at anthropogenically modified parts of the watershed area. Another important factor is that contact zones of territorial and aquatic complexes around the lakes are subjected to the most active exodynamic processes, such as abrasion, colmatage, mire formation, salinization; types of soil chemism dynamics are observed along when cyclic changes in the soil regimes. These unique conditions cannot but reflect on the properties of lakeside soils, including — solonchaks, which mirror the environmental conditions. Soils profiles are located in landscape microzone directly adjacent to the waterfront and are represented by primary, primary stratified, as well as typical and schorre solonchaks. Objects are characterized by a predominance in the composition of chlorides and/or sulfates, in places — with the participation of soda. Easily soluble compounds are represented by halite, thenardite and astrakhanite. The presence of gypsum does not allow the solonetz process to develop in soils remote from the water area of the lake. The findings of the studies show a wide variation of basic soil parameters and properties of solonchaks, determined by a number of local soil formation factors, such as steepness and shape of surrounding slopes, exposure, wind direction, diversity of soil-forming materials, properties of the stratified material, lake size, location, etc.

THE SOILS OF SUBORDINATE POSITIONS OF ZAURALYE STEPPE ISOLATES (FOR EXAMPLE SHIRA STEPPE) ^{[№ 10 ' 2015]}
Isolated steppes of Central Siberia is a very specific ecosystems. Territorially they are located in the nuclei of the intermountain basins. In this connection, the soils formed under the additional receipts of substances from the slopes of the mountains surrounding them, may differ in their basic properties from the analogous models of soils of European Russia. The objects of study in this paper served as a soil heteronomous positions, developed in conjunction with zonal automorphic. The composition of the soil of the study area is very diverse. Heterogeneity of components and their genesis ensures the availability of most difficult of the elements release mechanisms by weathering of rocks, as well as moving as a result of migration processes, accompanied by subsequent transformation and (or) their accumulation in the soil profile. The article briefly reviewed the conditions of soil formation Shira Steppe. The semiquantitative emission spectral analysis fulfiled by an accredited laboratory Geoecocentre State Geological Enterprise "Berezovgeologiya" (Novosibirsk) and part of the gross elemental composition of soils was determined on this basis. Geochemical conjugation heteronomous and autonomous soils with using the ratio of the same name is evaluated. The data statistical processing of medium and modal content of trace elements in soils various types of landscapes are submitted. Possible options for lateral migration of elements with Kr>1 and peculiarities their behavior in the studied objects, operating in arid conditions are viewed.

THE FEATURES OF ELEMENTS COMPOSITION FORMING OF SHIRA STEPPE SOILS OF ELUVIAL TRANSIT POSITIONS OF LANDSCAPE GEOCHEMICAL ARENAS ^{[№ 6 ' 2012]}
The results of researches of gross chemical composition of zonal soils of Shira steppe come into question. Possible reasons of forming of features of their modern element composition are marked. The specific of soil formative breeds of eluvial soils is exposed, in obedience to which a conclusion is done about the necessity of study of geochemical differentiation of territory, but not lateral migration.
