The article presents the results of studies of the macro- and microelement composition of alluvial soils in the Amur River valley. Based on the analysis of changes in the distribution pattern of microelements (rare earth elements), as well as values of geochemical indices (WIP, STI, R, CIA, CIW, PIA, V), it is shown that the formation of alluvial soils proceeded in different sections of the river in different geomorphological conditions and was influenced by sorting of detrital material and technogenic factors. Statistically significant differences between studied sections are confirmed by statistical analysis.
