Abstract:
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.
