The areas of gas-extraction cover sizeable territories in Russian federation.The soil cover changes as a result of natural gas field developing,construction of underground gasholders,the following amplification of geochemical influence of natural and artificial gas deposits,realization of drilling and exploitation works.During the technogenesis takes place the pollution of natural soils,their incomplete replacement on natural-technogenic,technogenic soils and ground.Thetop part of natural-teclnogenic and technogenic soils presents in redeposited turbic and techaogenic humic horizons,often polluted with residual mineral oils,polycyclic aromatic hydrocarbons,heavy metals (AYtur,pol).Technogenic horizons lay under humic horizon (TG).The particular place has sediment horizon that consist from drilling and drilling fluid.This horizon has montmorillonitic mineralogical composition and loam-clay texsture,large-monounit macrostructure,and the increased contents of magnetic fraction (TSd).The magnetic markers of sedirnentics horizon are octahedral lithogenic microparticles of magnetite with specific admixtures.Often sediment horizon is characterized by desagregated peptidized microstructure,a merged micromorphological structure (DA).Teclnogenic and sediment horizons have high content of organic carbon from drilling fluid (H); high content of bituminous substances (B).The magnetic markers of horizons,polluted by mineral oil,are spherical magnetic microparticles of ferric oxide with specific admixtures.Technogenic and sediment horizons of humid zone soils can be polluted by soluble salts-(S); these horizons can be alkaline (Sn) and have exchangeable sodium (ASK).In teclnogenic soils neogenic layers and horizons replace the top and median horizons of initial soils.In natural-technogenic soils mechanical disturbance and adjournment of sedimental horizons are localized in the top horizons of natural soils.At the same time there are some other changes in illuvial horizons of natural soils.Diffusion and convection fluxes of natural gas reach a soil cover through system of cracks in geological structure and change composition of soils air.During interaction between hydrocarbonic gases and soil are formed pedogenic bacteriomorphic nanodispersic particles of magnetite.The processes of pedogenic magnetite neoformation are most intensive in illuvial horizons of natural-technogenic and natural soils (Bnm).From the named position the profiles schemes of technogenic,natural-technogenic and natural soils of gas-bearing areas are accordingly represented as follows:AYtur,pol-TSdH-TGB-Bnm-C; AYtur,pol-TSdH-E-Bnm-C; AYtur,pol-E-Bnm-C.The division of antropo-technogenic soils is based on the ratio between processes of natural and technogenic soils formation.This division is buih into the system of taxonomic units of soils classification of Russia (2004).The central place in classification takes types of antropo-technogenic soils.Each type is characterized by community of properties,uniform system of natural genetic and technogenic soils horizons,integrated by similarity purposeful anthropogenous influences,processes and regimes of soil formation.In the structure of soil cover of gas-bearing areas,the natural soils,with new growth of pedogenic magnetite that is formed under the influence of natural gas received the most development.Significant territories are occupied by mosaics of natural polluted soils with technogenic soils.Soils and soil cover of gas-bearing areas have specific features in various natural zones.
