THE ERLANGEN AMS FACILITY AND ITS APPLICATIONS IN C-14 SEDIMENT AND BONE DATING

We report here on the radiocarbon dating of sediment samples from Bava ria using the Erlangen accelerator mass spectrometry facility. The abs olute time calibration of different sediment profiles, together with p ollen analyses, should establish a better chronology of climate and ve getation during Holocene in Bavaria. For an enhanced reliability of se diment dating, we measured different fractions such as bulk sediments, pollen grains, macrofossils and humic acids. For these fraction, we d escribe the separation methods and conversion to sputter targets. Furt hermore, we discuss the sample preparation for the dating of bones and present some results.
