CHEMICAL COMPOSITION OF SUSPENDED MATERIAL IN LARGE RIVERS OF RUSSIA AND ADJACENT COUNTRIES

Abstract

The analyzed (by mass spectrometry) samples were collected in different time (1953-1993) at downstream of 9 rivers - Amudar'ya, Ural, Volga, Don, Kuban', Rion', Severnaya Dvina, Ob' and Enisei. The results indicate rather close correspondence of the compositions of river suspended matter and sedimentary clay rocks. It means that the secondary diagenetic and catagenetic processes don't lead to strong changes of clay sediment initial composition.
