Thermoluminescence dating of Denizli travertines from the southwestern part of Turkey

The experimental determination of the formation age of a travertine collected from Denizli region in the southwestern part of Turkey was investigated using the thermoluminescence(TL) method. The first glow peak of calcite crystals of travertine limestone observed at 280°C was closely fitted with second-order kinetics and used for the evaluation of the accumulated dose. From the derived values of the trapping parameters for this glow peak, a mean lifetime can be predicted for ambient temperature, and hence the low peak should be stable enough to be used for dating this travertine. The thermoluminescence dating result is 828 ± 93 ka.
