Geochemistry of suspended matter in the Volga river marginal filter

Abstract

The first data on the long-term study of marginal filter (MF) of the Volga River is presented. The concentrations of suspended particulate matter, suspendforming chemical elements and microelements are considered. Ratios of enrichment suspension by chemical elements relative to the upper lithosphere are calculated. as well as their interrelations at different stages of the MF. It is shown that the sedimentary substance supplied by the sea with river flow, changes radically, both quantitatively and qualitatively.
