The overlying sediments which build up the spit landform (Unit 3b) yielded mid Holocene ages (4.2 ± 0.3 to 6.1 ± 0.4 ka). More specifically, one comparative OSL age from the
spit overlaps the TL age within 2s uncertainties, while the other yielded a significantly older TL age compared to the single grain OSL result (P31-20, Fig. 7), but still Holocene in age. In this case, the high single grain overdispersion of ~80% suggests an offset of several thousand years in the TL data, e.g. resulting from incomplete bleaching or dose rate related issues.
