Abstract

The paramagnetic centres used for ESR (Electron Spin Resonance) dating method should be thermally stable which is the main factor limiting the range of this method. In this work, thermal stabilities of the ESR centres in the cave deposites from the Aladaglar Massive and Alanya in Turkey has been investigated. The life times of the dating signal were calculated as about 4.0 and 3.7 years for G06 and G08 samples at the 10 degrees C depositing temperature. The activation energies of the centres are obtained the same, 0.7eV for both samples.
