Quartz OSL and polymineral post IR–IRSL dating of the Požarevac loess–palaeosol sequence in north–eastern Serbia

Luminescence dating at Border Cave: attempts, questions, and new results

“…Fading has already been reported for quartz of volcanic origin (Bonde et al, 2001;Tsukamoto et al, 2007) or from loess (e.g. Perić et al, 2021). Consequently, the fading rates for some of our quartz grains were measured.…”

“…However, additional issues have been raised, such as, first, the domination by medium and/or slow components which are thermally unstable (e.g. Jain et al, 2003), fading in quartz of volcanic origin, or in some loess (Bonde et al, 2001;Tsukamoto et al, 2007;Perić et al, 2021), and, secondly, differences in competition for free charges, which can occur during stimulation and/or dosing and/or heating, between the traps and luminescence centers for natural and artificial dose rates (Bailey et al, 2004a). The consequence of this difference in competition is that the regenerative dose response curve is not equivalent to the natural dose response curve, and/or the natural test dose signal is not a good surrogate for the sensitivity of the natural signal (e.g.…”

Testing the Applicability of Quartz and Feldspar for Luminescence Dating of Pleistocene Alluvial Sediments in the Tatra Mountain Foothills, Slovakia

“…The obtained quartz ages ranged from 40-60 ka (Table 3), but showed unreliable results, which could have multiple reasons, among which an important factor is that the sediment samples in this study have doses higher than 200 Gy, which is usually beyond the reliable natural dose range for quartz luminescence dating (Buylaert et al, 2012;Avram et al, 2020;Perić et al, 2021).…”

“…At present, we are uncertain about the reason for such discrepancy between the investigated samples. One explanation may be that the samples originate from diverse primary sources which might have caused the difference in the signal characteristics (Perić et al, 2021). The decay curve shape (Fig.…”

Data on the saturation behaviour of the 63-90 µm quartz from the Carpathian Basin

“…This agrees with the findings of Timar-Gabor and Wintle [ 6 ], Timar-Gabor et al [ 7 ]. and Perić et al [ 8 ]. for Romanian and Serbian loess respectively, where it was concluded that quartz from this region cannot be used for measuring a known given dose in the high dose range and that most measurements overestimated the expected doses.…”
