This study describes the luminescence characteristics of quartz of Upper Pleistocene loess of the Middle Rhine area. The loess/palaeosol sequence of the Schwalbenberg near Remagen comprises a multitude of interstadial soils and soil sediments that have been dedicated to the Marine Isotope Stage 3 (MIS 3). These weak calcaric cambisols and their derivates are underlain by loess and soil sediments of MIS 4 to MIS 5 and covered by loess sediments and intercalated gelic gleysols of MIS 2. We applied luminescence dating of quartz and feldspar of drill core samples and observed an age discrepancy within both data sets. The quartz ages were clearly younger than the feldspar ages, because of thermally unstable signal components of the quartz luminescence signal. Therefore, we regarded the quartz samples of the lower parts of the drill core as unsuitable for luminescence dating. This underestimation did not affect the quartz samples of the upper part of the drill core which was indicated by age control that was provided by the Eltville tephra layer. Geochemical analysis based on X-ray fluorescence showed that the sediments in the upper part and the lower part of the drill core have different geogenic finger prints most likely due to changing source areas of dust and sediment allocation. We assumed that these different facies types were the reason for the luminescence behavior of the quartz samples.

“…The advantage of OSL is that the signal is known to bleach rapidly when quartz grains are exposed to light and to be stable for millions of years once shielded. However, some quartz has been unsuitable for OSL dating due to either low signal levels (Preusser et al, 2006) or signal instabilities (Steffen et al, 2009). In such contexts, feldspar IRSL often provides an alternative, although this signal is known to suffer from anomalous fading, causing age underestimation (Wintle, 1973;Huntley and Lamothe, 2001).…”

“…In view of the observations that have been made regarding the potential contribution to the initial part of the OSL decay curve from a medium decay component with a relatively short half life (Li and Li, 2006;Steffen et al, 2009), the early background (EBG) subtraction procedure (Ballarini et al, 2007;Cunningham and Wallinga, 2010) was also applied, using signal integration intervals of 0-800 ms and 800-1600 ms for signal and background respectively. The ratio of the D e values calculated using EBG and PBG subtraction was employed to screen aliquots for the presence of the medium decay component.…”
