ESR DATING OF TOOTH ENAMEL FROM KARAIN EXCAVATION (ANTALYA, TURKEY)

Samples of fossil tooth enamels taken from different depths of Karain Cave (Antalya, Turkey) were studied by the ESR method. The accumulated doses (D(E)s) of the samples were determined using the paramagnetic c enter at g = 2.0020 +/- 0.0003 by means of three different microwave p ower conditions. It is found that the dating signal at g = 2.0020 (Del ta Hpp approximate to 0.34 mT) is disturbed significantly by the isotr opic signal at g = 2.0007 +/- 0.0003 at high microwave power. The life time of this signal is significantly smaller than the lifetime of the dating signal. However, the statistical uncertainty caused by differen t microwave powers is still within the total uncertainty in the age de termination of the tooth enamels under investigation. The ESR ages of the samples were calculated using early uranium (EU) and linear uraniu m (LU) uptake models. The ages due to EU and LU models are in agreemen t within an error of 10% due to the low uranium content of the samples .
