Biology Bulletin of the Russian Academy of Sciences. Radiocarbon dating of the pollen concentrate from late Pleistocene syngenetic ice wedges was carried out using accelerator mass spectrometry AMS in Seyakha and Bizon sections. Comparison of the results with palynological data and the results of AMS radiocarbon dating previously obtained for other organic fractions of the same samples allowed the accuracy of dating of different fractions to be evaluated. Quantitative criteria for data evaluation in terms of possible autochthonous or allochthonous accumulation of the material on the basis of pre-Pleistocene pollen content in these samples were considered. Paleoecological information content of pollen spectra from late Pleistocene syngenetic wedge ice was evaluated. Unable to display preview.

The paper presents the results of the AMS radiocarbon dating of moss macrofossils which seem to be too old in the context of palynological data. The lack of agreement between the obtained results of radiocarbon dating and pollen analysis has been discussed. Some possible causes of the discrepancies between the results of radiocarbon dating and palynological dating have been given.
