Optical dating of archaeological samples using a single aliquot of quartz stimulated by blue light

The single aliquot additive dose method of equivalent dose determination was applied to quartz from heated archaeological materials, using luminescence stimulated by blue light. The quartz was extracted from pieces of pottery and kiln in an area of archaeological interest in Suwon region, south of Seoul, Korea. The dates obtained were in good agreement with the ages derived by archaeological evidence. It is concluded that the additive dose single aliquot method of determining equivalent dose, with correction for re-use of the aliquot, should contribute significantly to optically stimulated luminescence dating procedures, particularly when the amount of sample separated is limited. Additionally, some luminescence images from quartz samples using a CCD camera are presented and relationships between AGTL, TL and OSL are discussed. (author)
