Аннотация: An accumulation of Cu and As is found in the peat deposit of an eutrophic marsh together with anomalously high concentrations of Ga in some layers. The element dispersed in the peatbog depth in the greatest extent is Zn, and in equally small portions there is dispersed In and Au. The main factors of the biogeochemical migration of Cu, Zn, In, Au, As, Ga in peatbog formation are: the lithological peculiarities of the territory, the oxidation-reduction zonality of the deposit depth within the limits of oxidation and the reduction background, the quality of the humus sorbing barriers, the carbonate equilibrium of marsh waters, and anthropogenic factors. A tendency to accumulate Zn migration streams in the bedding of marsh forests in South West Siberian taiga is observed.
