UDC (551.215.6:553.065.3):550.42(292.518) GEOCHEMICAL AND MINERALOGICAL CHARACTERISTICS OF BOTTOM SEDIMENTS IN THE SIZIY MUD POOL (UZON CALDERA, KAMCHATKA)

An integrated approach (XRF-SR and atomic absorption spectrometry) has been used for detailed investigation of the chemical elements distribution in sediments of the Siziy thermal lake (Uzon Caldera, Kamchatka). Research findings indicate that there are three layers varying in concentration of trace elements. It can be distinguished two groups of elements with the opposite distribution trends: 1 – Sr, Sb, Y, Zr, Zn, Ba; 2 – K, Rb, Ca, As, Fe, V, Mn, Ti. Data on the elements content can be used as markers in the setting of the epithermal hydrothermal mineralization.
Key words: XRF-SR, thermal lakes, Uzon Caldera, bottom sediments.
