Landscape-geochemical zoning of the Amur Basin (Russian Territory)

This study presents the landscape-geochemical characteristics of the Russian part of the Amur Basin and highlights the influence of geographic factors on the formation of the soil geochemical systems. The spatial variability of the element concentrations in the background soils is found to be a function of the mobility of the elements in organometallic compounds. The formation of the landscape-geochemical features is briefly reviewed. New approaches and principles of landscape-geochemical zonation are used to compile the map of the landscape-geochemical zoning of the Amur Basin on a scale of 1: 2500000, which shows the landscape-geochemical features reflecting the spatial variability of the element concentrations and the conditions of the element migration in the soils.
