C-14 AMS MEASUREMENTS FROM THE LATE WEICHSELIAN PART OF THE SWEDISH TIME-SCALE

Accelerator mass spectrometry measurements on plant macrofossils from the older part of the Swedish Time Scale, a chronology spanning over t he past 13,000 calendar years, indicate a good agreement between varve years and calibrated ages (tree-rings, U-Th) between ca. 10,500 and c a. 12,000 calendar years BP. Around 12,000 varve years, the varve/radi ocarbon discrepancies seem to reach a maximum, while the U-Th/radiocar bon differences increase steadily.
