AbstractA method of identifying the most appropriate thermal annealing or preheating treatment for optical dating of quartz is proposed. The procedures can also be used in equivalent dose determination using single and multiple aliquot techniques. It is found that optically stimulated luminescence (OSL) from quartz can be either increased or decreased after preheating. An increase in OSL signal is attributed to thermal charge transfer from non-OSL traps into OSL traps or change in OSL sensitivity. This enhancement is dependent on preheating time and temperature. The decay of the OSL signal by heating is mainly from a single type of OSL trap. Implications for quartz optical dating are discussed.
