CHRONOSTRATIGRAPHY OF THE OKUNIN AND CZEREPACHA LAKE-MIRE GEOSYSTEMS (VOLHYNIA POLESIYE, NW UKRAINE) DURING THE LATE GLACIAL AND HOLOCENE
Cores of lacustrine and lacustrine-peat deposits from the Okunin and Czerepacha sites were examined using the following methods: sedimentological analysis, radiocarbon dating, pollen, ostracod and geochemical analyses. 137 Cs distribution was determined in the top parts of these deposits. The obtained results allow us to reconstruct the main stages of evolution of the lake-mire geosystems in relation to regional changes of environmental con- ditions during the Late Glacial and Holocene.
