| Pollen extracted from ocean and wetland sediments cored from the eastern Canadian Margin, James Bay region, and Atlantic provinces of Canada have been radiocarbon dated and results are reported here. Pollen dates from ocean sediments were compared with marine carbonate (mollusk shells or foraminifera) dates from the same core levels, dates for which validity was assessed via correlations with other cores, and for which reworking has been excluded. Pollen samples from 3 tidal wetlands were taken from levels dated with Cs-137 and Pb-210 profiles. Pollen dates from 2 additional wetlands were compared with C-14 dates of botanical macrofossils. Most pollen dates disagree with C-14 dates based on macrofossils or carbonates, with age differences typically... |
