Optically stimulated luminescence (OSL) and Thermoluminescence (TL) are applied in this study to date a Lateglacial and Holocene aeolian sediment sequence. Quartz and potassium rich feldspars extracted from dune sands from western Germany were dated using both multiple-aliquot (MA) and single-aliquot (SA) protocols for luminescence dating. This particular dune section was chosen for this test study, because an independent age control is provided by a horizon of the Laacher Seetephra (12,880 a). In contrast to the results for potassium feldspars, which show underestimation of up to 25%, the quartz fraction provides promising results with respect to the presumed geological ages.
