Abstract

Samples of bottom sedimentary material of drilling column 02a from Teletskoye Lake were investigated by synchrotron radiation X-ray fluorescence analysis (SRXFA). Geochemically important elements (Zn, As, Fe, Rb, Sr, Y, Zr, Nb, Ba, La, Ce, Pr, Nd) were determined. Results reveal the difference between sedimental layers associated with rhythmic layer-by-layer oscillation of mineral composition and grain size. A conclusion is drawn about the ability of using of the international geologic standard BIL-1 in studying sediments of Teletskoye Lake by means of a reference sample method in SRXFA.
