The application of the IRSL dating technique to feldspars from Kayseri-Turkey

The aim of this study is to test the suitability for luminescence dating of polymineral sediment samples taken from Kayseri, Turkey, an important area for both geologists and archaeologists. Feldspars isolated from samples were heated at different temperatures for 10 min to optimise the preheat temperature. The optimal pre-heat temperature was found to be 220°C for 10 min. The IRSL technique was applied using both single- and multiple-aliquot procedures. Although both of these methods gave comparable results, the age obtained using multiple-aliquot procedures was found to be more reliable than those obtained by other methods. The results obtained were in good agreement with those of geological interpretations.
