TRACE ELEMENTS IN GROUND WATERS AND SURFACE WATERS OF THE SENTSA RIVER BASIN (EASTERN SAYAN RIDGE)

Abstract

: The paper presents the first data on the distribution of trace elements in ground waters and surface waters of the Sentsa River basin (Eastern Sayan Ridge). It is shown that the Khoyto-Gol thermal waters are significantly en-riched in Li, Be, B, Si, Mn, Ge, As, Br, Rb, Sr, Cs, Ba, W and depleted in Al, P, Cu, Zn, Ag relative to river waters and rainwater. The REE distribution spectra in ground waters and surface waters are characterized by a strongly positive Eu anomaly and the prevalence of light REE over heavy REE.
