In the dissertations the theoretical generalisation of complex geochemical researches in a zone of aeration of Southeast Donbass and the new decision of a problem of the forecast of technogenic loading in coal-mining region that is connected with features of metals distribution both on lateral vertical direction of a soil profile and dynamics of technogenic geochemical anomalies that in the turns conducts to geochemical autostabilization of the geological environment are presented. For the first time in the course of fulfilled works it is established that in soils there is the raised background of Mn, Hg, Ti, Zn, F, As, Pb in Southeast Donbass in comparison with adjacent region, of the Voronezh antheclise slope. It conected with a small capacity of a sedimentary cover (up to 18m) and the increased maintenance of these elements in rocks of Middle Carboniferous of Southeast Donbass. It is established, that regional thrusts of the Southeast Donbass and intersecting their faults are characterised by presence of abnormal zoning of paragenetic association of microelements such as Hg, Pb, Zn, Tl, As, concentration of Hg in soil air and Hg, As, Zn, Pb, Tl in soil depend on an order of faults. For the first time, as a result of the fulfilled works it is established that technogenic geochemical anomalies of Southeast Donbass have 2 zones of the maximum accumulation of microelements: I- 0-10сm; II- 25-35сm. Depth of 35сm is the bottom border of technogenic geochemical anomalies in eluvial landscapes of Southeast Donbass. It was shown by researches that the vertical and horizontal zoning of chemical elements distribution in a zone of aeration of Southeast Donbass is caused by its features. The increased contents of carbonates reduced by contents humus in horizon A in comparison with other climatic zones of Ukraine and presence of a coal dust on a surface. It is established that soil the profile of a zone of steppe landscapes of Southeast Donbass is complex barrier system. In the eluvial landscapes 8 geochemical barriers are established: A - oxygen, Е - acid, G - sorption Gб - biosorption on the depth of 0-15сm; B-a redox-barrier on the depth of 25-35сm; C - gley on the depth 35-50сm; D - alkaline on the depth of 50сm to left confining layer; G (МnO2) - sorption bymanganeseoxides; Gcl - sorption by clay components of soils on which accumulation of metals occurs On all thikness of a zone of aeration. In aquatic landscapes there are 7 geochemical barriers (carbonate D is absent). On latheral the minimum of 2 geochemical barriers is traced: A-oxygenic and G- sorption. It is determined that rocks of coal mining which have been generated in the conditions of coastal lithogenesis of Middle Carboniferous and in further metamorphised, at change of thermodynamic conditions have passed from a stable condition in metastable through 4 stages of transformations which are accompanied by formation of new compounds and minerals, owing to spontaneous processes which arise in system. It again comes back in a stable condition, inherent in hypergene conditions of Donbass. It is is determined that chemical elements on rates of dispersion from a soil cut of horizon А0 (0-10-15cm) of eluvial landscapes shares on three groups: 1) elements with the short period of dispersion - about 3 years Cl, F, Na, Br, Hg, As, Cd; 2) elements with the average period of dispersion - 3-15-17 years- Pb, Ni, Co, V, Ge, Ga, Be, Zn, Cu, Ag; 3) elements with the long period of dispersion> 17-20 years Mn, Ti, Al, Fe, Li. Law of a soil profile and aeration zone to geochemical autostabilization is established All mineral, organic and technogenic connections which have been generated in conditions which differ from conditions of landscape-geochemical unit where they have got from the outside, under the influence of geochemical and biochemical spontaneous processes deposit, redistributed and sediment in those forms which are inherent given taxonomic unit of zone hypergenesis. The geochemical system of aeration zone is able to regulate spontaneously the balance of geochemical components of that volume and those forms which necessary for correct functioning concrete taxonometric units of hypergenesis zone.
