Nemuno ledynmečio periglacialinės nuosėdos šiaurės vakarinėje Lietuvos dalyje
The pollen of the tree group amounts to 40%. Among those dominating are Pinus (40-58%) and Betula (24-36%) while rather a lot of Betula nana L. pollen were found (Fig. 2). Estimating the pollen spectra by distribution of individual groups of plants, by frequency and by the species composition of gra...
