The measurement sequence, the single aliquot regenerative dose . A series of checks was carried out on each grain to ensure that the luminescence signals were reproducible, and that they were derived from quartz.
The measurement sequence, the single aliquot regenerative dose protocol, was used to obtain values for the total effective radiation dose to which each grain had been exposed since burial. This led to acceptance of less than 5% of the grains. An estimate of the radiation dose for the sand unit was obtained by combining the values using the central age model.
Single Quartz OSL ages can be determined typically from 100 to 350,000 years BP, and can be reliable when . Advances in Optically Stimulated Luminescence Dating of Individual Grains of Quartz from Archaeological Deposits". Evolutionary Anthropology.
Single Quartz OSL ages can be determined typically from 100 to 350,000 years BP, and can be reliable when suitable methods are used and proper checks are done. Feldspar IRSL techniques have the potential to extend the datable range out to a million years as feldspars typically have significantly higher dose saturation levels than quartz, though issues regarding anomalous fading will. need to be dealt with first. Ages can be obtained outside these ranges, but they should be regarded with caution.

Single-grain optically stimulated luminescence (OSL) dating of quartz has been widely used for dating sediments, because of its inherent advantages over the single-aliquot method in identifying poorly behaved grains and dealing with insufficiently bleached samples and those affected by post-depositional mixing (. Understanding the intrinsic variability of OSL behaviors at the single-grain level is important for dating, since De estimation can be dependent on these behaviors, .
