GEOCHEMICAL BARRIERS IN SOILS AND LANDSCAPES OF THE ANADYR TUNDRA
Abstract
The interaction of radial and lateral subsurface geochemical fluxes on the pairing elementary landscapes of the lowland tundra is analyzed. Two typical Anadyr lowland urochishches were examined to describe the structure of geochemical landscapes and tundra soils, and the concentrations of Fe, Mn, Zn, and Cu within the area and along the section. The regularities and specific features of the location of low and high geochemical anomalies in correlation with oxidative, gleyic and sorption barriers in soil and landscape are revealed. It was concluded that the radial and lateral geochemical barriers form united geological bodies in landscapes. Their morphology depends on the topography of the impermeable permafrost horizon.
