Abstract [en]

The chronology of two adjacent Danish Lateglacial sedimentary sequences with well- developed layering of alternating aeolian sand and organic matter has been investigated using both Optically Stimulated Luminescence (OSL) and Accelerator Mass Spectrometry (C-14). Both sites are known to cover at least the period Bolling to Younger Dryas, with the so- called older and younger coversand types present at both localities. Typical overall uncertainties with the OSL data are about two to five times those of the C-14 ages, but both data sets contain clear outliers. When these are excluded, OSL ages appear to be systematically slightly younger than the C-14 ages, by about 10%; possible reasons for this are discussed. The investigation stresses the importance of making several age estimates from any single locality. The older coversand type makes up the pre- Bolling and most, or possibly all, of the Bolling (which also has the highest net accumulation rate). Deposits of the younger coversand type are dominant in layers younger than the Bolling.
