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

一组来自赞比亚维多利亚瀑布附近广泛风沙岩的样品被用来探索几种不同的方法来计算光激发发光 (OSL) 年龄，这些方法解释了饱和石英颗粒的影响。样品的 Beta 剂量率异质性和早期 OSL 信号饱和加剧了饱和晶粒对计算的等效剂量 (D _e ) 值的影响。无法计算 D _e值的饱和颗粒通常会被拒绝，但它们包含的最小掩埋剂量信息会对样本的平均 D _{e产生重大影响}价值。本研究比较了多种用于组合发光测量的技术，这些技术能够包含这些数据及其对拒绝具有早期 OSL 信号饱和的晶粒的标准的敏感性。_{测试的方法被发现有不同的优点和缺点，但他们计算的De}值之间的合理一致性表明，与用于组合数据的特定方法相比，包含来自饱和晶粒的数据对计算的_De值产生更显着的差异。
