Реферат:	eng: Cores of bottom sediments from epiglacial Donguz-Orun Lake (Cis-Elbrusian, Northern Caucasus) have been studied. Here we present descriptions of the sampling techniques, sample preparation, and analytical procedures by the X-ray fluorescence method. The sedimentation rate, estimated by calculation of peaks of the Rb/Sr ratio as well as employing isotope concentrations of Cs-137 and Pb-210 in the upper parts of the core, permitted us to assume the annual character of the regularly laminated sediment. A statistically significant correlation between the concentration variations of certain chemical elements and their groups in the sediment against normalized meteorological data from the Terskol meteorological station has been revealed. This makes the studied object applicable for development of high resolution palaeoclimate reconstructions.
