Comparison of Sample Preparation Techniques Used in Luminescence Dating Methods

Abstract

Age determination by the luminescence dating method is based on measuring the luminescence of samples that contain quartz or similar minerals. Accurate determination of the luminescence signal is essential and closely related to the sample preparation. Many kinds of techniques are used for sample preparation in Optically Stimulated Luminescence and Thermoluminescence dating. In this study, different sample preparation techniques, including crushing by hand or mortar, sieving by hand or sieve shaker and chemical application were compared. Different groups of samples were prepared and then the OSL and TL luminescence signals were examined. According to results, the best sample preparation techniques were determined.
