Pollen Assemblages and Plant Macrofossils in Holocene Deposits of Maloe Olen’e Lake (Kaliningrad Oblast)

Resumo

Sediments of Maloe Olen’e Lake in the central part of the Kaliningrad oblast were subjected to analysis of the botanical composition of peat, pollen analysis, and radiocarbon dating. Four local pollen assemblage zones as reflecting the dominant plant communities of the surrounding territories during the Holocene were assigned. Analysis of plant macrofossils resulted in the identification of the stages of floating mat vegetation development in the Late Holocene. The atypical sequence of peat deposition, with transition mire peat located above raised bog peat, was identified. Sediment accumulation rate was calculated according to radiocarbon dating.
