Challenges of dating quartz OSL samples with saturated grains: Lessons from single-grain analyses of low dose-rate samples from Victoria Falls, Zambia

A suite of samples from an extensive aeolian sandscarp near Victoria Falls, Zambia was used to explore several different methods calculating optically stimulated luminescence (OSL) ages that account for the effects saturated quartz grains. Beta dose rate heterogeneity and early OSL signal saturation exacerbate impact grains have on equivalent (De) values calculated. Saturated cannot calculate De are often rejected but minimum burial information they contain can a significant sample's average value. This study compares multiple techniques combining measurements enables inclusion this data their sensitivity criterion rejects with saturation. The tested found advantages disadvantages, reasonable agreement between suggests including makes more difference calculated than specific method combine data.
