Holocene, Chukotka, spore-and-pollen analyses, Quaternary deposits, paleogeography


Results of radiocarbon dating and spore-pollen analysis of lacustrine sedi ments in the Nyrki sectionfrom the Yurumkuveem river basin (Central Chukotka) show the wider distribution of floodplain forests and the warmer  climate in this time in the region in the early Holocene than in the present time. The occurrence of larch (Larix) in the vicinity of Nyrki lake in the early Holocene is also discussed. Our data suggest that the larch range was expanded to the Yurumkuveem river valley and its inflows during the early Holocene, but this tree disappeared from there in the late Holocene.
