Luminescence dating of a geological sample from Denizli, Turkey.
Recent advances in luminescence dating have led to increasing application of the optically stimulated luminescence (OSL) technique to investigate the sedimentation of the depositional environmental samples. In this study, a geological sample was dated by using OSL technique. The sample was collected from a main fault line located in Denizli, Turkey. It was prepared using the fine grain method. The optimum preheat temperature of 205 degrees C and duration value of 3 min are determined through a sequence of experiments. For the calculation of the age of the samples the equivalent dose (ED) was measured using both the multiple-aliquot and single-aliquot techniques. The annual dose (AD) was obtained by measuring the concentration of the major radioactive isotopes in the samples by using a high purity Ge detector. The age of the sample was found to be between 5490 +/- 300 years and 6000 +/- 320 years.
