“…They conclude that that D e estimates above this value are likely to be underestimated. The available dataset of three SAR-OSL measurements of this study does not allow to construct a reliable natural DRC but the L n /T n values range between 3.6 ± 0.14 (1A9H2), 4.0±0.37 (1A6H2B) and 4.0±0.12 (1B2H2), indicating no increase with increasing natural dose, whereas the laboratory-generated dose response curve shows a constant increase up to 1240 Gy, as observed by Chapot et al (2012) (see also Sect. 7).…”

“…They also report on the slow growing dose response curve beyond 400 Gy, which is represented by a linear component. Chapot et al (2012) have analysed this problem by comparing a natural dose response curve, which was constructed from the test dose normalized natural OSL signals of seven samples from a Chinese loess record, and the laboratory generated dose response curves (DRC). They observed a continuous increase of the laboratory generated normalized OSL signal above 500 Gy but no growth in the equivalent natural DRC at these Table 3.…”

Abstract. This study tests the paleomagnetic and proxy-data based Mid- to Upper Pleistocene sediment deposition history of Lake El'gygytgyn by applying different approaches of luminescence dating techniques on sediment cores taken from the centre of the 175 m deep lake. For dating polymineral and quartz fine grains (4–11 μm grain size range) were extracted from nine different levels from the upper 28 m of sediment cores 5011-1A and 5011-1B. According to the independent age model, the lowest sample from 27.8–27.9 m below lake bottom level correlates to the Brunhes-Matuyama (B/M) reversal. Polymineral sub-samples were analysed by infra-red stimulated luminescence (IRSL) and post-IR IRSL measured at 290 °C (pIRIR290) using single aliquot regenerative dose (SAR) sequences. SAR protocols were further applied to measure the blue light optically stimulated luminescence (OSL) and thermally-transferred OSL (TT-OSL) of fine-grained quartz supplemented by a multiple aliquot approach. Neither low temperature IRSL measurements at 50 °C nor any OSL dating approach on quartz yielded reliable results. Deconvolution of their dose response curves revealed a pseudo-increase of the dose response curves and explains the observed underestimation. The pIRIR protocol applied to polymineral fine grains was the only luminescence technique able to provide dating results of acceptable accuracy up to ca. 700 ka when correlated to the existing proxy-data and paleomagnetic based age record. We present the potential and limits of the different dating techniques and a correlation of pIRIR290 results with the proxy-data based age model.

“…All OSL ages were in stratigraphic agreement and provided ages between 20 and 50 kiloyears (ka). D e values remained below 150 Gy and do not fall in a region for which methodological problems have been reported (Chapot et al, 2012;Lai, 2010;Lowick et al, 2010;Timar et al, 2010). Therefore these ages are considered reliable.…”

Abstract:Recently exposed loess-palaeosol sequences in the northern Alpine foreland close to Bobingen (southern Germany) were investigated with a multi-proxy approach combining isotopic, geochemical, lithological, and micropalaeontological methods. Luminescence ages date the sections into the Middle and Upper Würmian periods corresponding to Marine Isotope Stages 3 and 2. A gleyic soil horizon at the base was dated to 45 ka and provided a palynoflora dominated by Poaceae, Cyperaceae, and Pinus, as well as frequent aquatic taxa. Lacustrine conditions prevailed after the gley formation until 30 ka, providing a comparatively diverse lacustrine fauna dominated by aquatic gastropods and the ostracod species Candona candida. At the transition to the Upper Würm, climatic conditions became harsh, indicated by accelerated deposition of more coarse-grained loess, organic geochemical indicators, and scarceness of biotic remains. Two tundra-gley horizons in the Upper Würm point to short phases of climatic amelioration with higher humidity also evidenced by reoccurrence of ostracod and aquatic gastropod remains. We propose that these climatic ameliorations were coincident with the Greenland interstadials 4 and 2.Published by Copernicus Publications on behalf of the Deutsche Quartärvereinigung (DEUQUA) e.V.

“…From the viewpoint of the obtained results we should also consider whether the luminescence results obtained for quartz can be underestimated in connection with the quartz luminescence properties. In the literature, several workers have reported age underestimation in OSL dating (Lowick et al, 2010;Timar-Gabor et al, 2011, Chapot et al, 2012 for high D e doses (more than 150 Gy). In the S1 unit, for all samples the equivalent doses (D e 's) show a clear change with depth for all fractions.…”

OSL chronostratigraphy for loess deposits from Tyszowce – Poland

et al. 2017

Abstract:The presented work concerns a loess profile located in Tyszowce, in the eastern part of Poland on the Volyn Upland, close to the Ukrainian border. The investigated loess formation is well preserved and is characterised by clear stratigraphic units providing an opportunity to refine the loess chronostratigraphy in Poland. In the paper, we present luminescence ages of loess from the last glacial cycle in SE Poland (up to about 100 ka) together with seven radiocarbon ages. Twenty-one samples were collected and dated using infrared (post-IR IRSL) and blue light stimulated luminescence dating. Two fractions were used, namely polymineral fine grains (4-11 µm) and medium sized quartz grains (45-63 µm). The obtained luminescence ages show very good agreement of both methods in relation to loess deposits, however for the fossil soil units the post-IR IRSL method yields older ages. Radiocarbon dates also confirm luminescence chronostratigraphy for younger units. Moreover, the luminescence results are supported by detailed analyses of grain size distribution, carbonate content and magnetic susceptibility variations allowing to create a comprehensive picture of chronological evolution of this site.
