Towards an improvement of optically stimulated luminescence (OSL) age uncertainties: modelling OSL ages with systematic errors, stratigraphic constraints and radiocarbon ages using the R package BayLum

Abstract: Abstract. Statistical analysis has become increasingly important in optically stimulated luminescence (OSL) dating since it has become possible to measure signals at the single-grain scale. The accuracy of large chronological datasets can benefit from the inclusion, in chronological modelling, of stratigraphic constraints and shared systematic errors. Recently, a number of Bayesian models have been developed for OSL age calculation; the R package “BayLum” presented herein allows different models of this type t… Show more

“…A combination of highdensity sampling and Bayesian analysis has been demonstrated to provide robust age-depth models (Combés and Philippe, 2017;Zeeden et al, 2018;Perić et al, 2019;Fenn et al, 2020). Bayesian modeling can reduce overall uncertainty by simultaneously modeling the D E distributions and the individual components of the D R (Guérin et al, 2021) and can help clarify occasional age inversions in the chronostratigraphic data. The main advantage of luminescence agedepth models, compared to radiocarbon dating, is the larger time range accessible by the luminescence technique and the ability to date sediments void of organic material.…”
