| Yhteenveto: | Title screen The results of mineralogical-geochemical studies of the oligotrophic pine-fruticulose-sphagnum segment of Vasyugan Swamp (West Siberia) in the winter of 2017 are presented. A mathematical model is developed for the depth distribution of chemical elements in water and acid extracts of peats, organo-mineral sediments, and inorganic soil. It is shown that two complex geochemical barriers related to the changes in filtration properties of soils and contributing to the formation and/or accumulation of Fe compounds and other chemical elements function in the peat deposit. The first (oxidizing, reduction, sulfide, and adsorption hydroxide) barrier is found approximately at a depth of 0.40-1.25 m; the second (alkaline carbonate and hydrolytic, adsorption hydroxide, clayey, and carbonate) barrier lies in the lower layer of the peat deposit (a depth of 2.25-2.50 m). The result obtained is important for understanding the production-destruction methane cycle. Режим доступа: по договору с организацией-держателем ресурса |
