Abstract
The distribution of 152Eu, 154Eu, and 155Eu isotopes along the vertical profiles of several floodland and bottom sediments of the Yenisei River was studied. The decrease of 154Eu/152Eu and 155Eu/152Eu ratios down the profiles is described by exponential function. This makes it possible to determine the age of floodland and bottom sediments of the Yenisei River and calculate their average formation rate.
