“…Beta and gamma dose rate contributions arising from the cobbles and the surrounding matrix were calculated using the relevant infinite‐matrix dose rates, the linear attenuation coefficients by Sohbati et al. (2015), and the methodologies described there, based on Aitken (1985) and the principle of superposition (Fig. S1).…”

“…Here, we consider the signal to be well‐bleached (and thus useful for deriving burial ages) if the pre‐burial signal (M) is predicted to have been <5% of the signal acquired during burial (N) (al Khasawneh et al. 2019).…”

We constrain the age of a cobble beach ridge system in Greenland using Optically Stimulated Luminescence (OSL) dating of buried cobble surfaces. Luminescence signals from six cobbles are measured using infrared (IR) stimulation at 50 °C (IR50) and 180 °C (pIRIR180); these cobbles represent four progressively younger beach ridges lying between ~35 and ~6 m above present sea level. Luminescence–depth profiles show that the IR50 signals in all the samples and pIRIR180 signals in four out of six samples are well bleached to depths >1.2 mm into the cobble surfaces. Equivalent doses in well‐bleached cobble surface slices (i.e. <1.2 mm) are measured and divided by the effective environmental dose rate to the cobble surfaces in order to derive burial ages. Both IR signals are corrected for anomalous fading using the sample‐specific ratio of the field to the laboratory saturation levels. Our results are consistent with a depositional model predicting that the investigated portion of the beach ridge system built out continuously during relative sea level fall between ~5.3 and ~1.9 ka ago. The optical ages suggest that the rate of construction varied considerably, with the highest rates ~3.4 ka ago. Additionally, the lowest‐elevation beach ridge investigated here provides the first evidence for a higher‐than‐present relative sea level, between 1.5 and 2 ka ago, in the Disko coastal region.

“…Despite the variations in the form and function, the chronology of these structure has always been a debate among scholars because of the lack datable materials. However, these sites now are potentially datable using luminescence rock surface dating technique as seen in this case and previous studies in the region (Sohbati et al, 2015;al Khasawneh et al, 2018). ̅̅̅̅̅ is the trap-emptying rate at the surface (s -1 ), μ the light attenuation coefficient (mm -1 ).…”

“…Promising recent work has shown the potential of using the optically stimulated luminescence (OSL) signal from rock surfaces to date the emplacement of gravel pavements and blocks in both archaeological (11)(12)(13) and geological contexts (14,15). OSL rock-surface dating has also been used to constrain the exploitation of a lithic raw material quarry (16) and the timing of a whetstone usage (17).…”

Direct dating of lithic surface artifacts using luminescence

et al. 2021

Archaeological surface assemblages composed of lithic scatters comprise a large proportion of the archaeological record. Dating such surface artifacts has remained inherently difficult owing to the dynamic nature of Earth-surface processes affecting these assemblages and because no satisfactory chronometric dating technique exists that can be directly applied to constrain the timing of artifact manufacture, discard, and thus human use of the landscape. Here, we present a dating approach based on optically stimulated luminescence (OSL)—OSL rock-surface burial dating—and apply it to a lithic surface scatter in Tibet. We generate OSL burial ages (age-depth profiles) for each artifact, outline the methodological complexities, and consider the artifact burial ages in the context of local-scale Earth-surface dynamics. The oldest age cluster between 5.2 and 5.5 thousand years is likely related to quarrying activities at the site and thus represents the oldest chronometric age constraints for human presence on the south-central Tibetan plateau.
