Abstract
Lateral and radial geochemical structure of bog catena soils of Western Siberia middle-taiga subzone has been investigated on the base of B, Na, Mg, Al, P, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Rb, Sr, Y, Zr, Mo, Cd, Sb, Cs, Ba, Hf, W, Pb, Th, U and lanthanoides content. Bog catena is characterized with high contrast of radial distribution of most studied elements. Lateral differentiation is significantly lower than radial one and is monotonous for most elements. In bog catena soils of Western Siberia middle-taiga subzone there are investigated correlations between elements content and soils characteristics that are mainly determined by specific peculiarities of ecosystem development.
