Abstract

This work on the luminescence dating method (TL/OSL) has been carried out following the recent installation of a Risø TL/OSL-DA-20 reader. In the first step, the method has been successfully tested and applied on quartz grains (reference samples) using the Single-Aliquot Regenerative (SAR) protocol. For each sample, we made the purity test, we estimated the dose and the preheat temperature, and then we calculated the equivalent dose. In the second step, the method has been applied on quartz grains of sediment from the Middle Atlas (Immouzer Kandar-north of Fez). In this part, we have highlighted the sampling procedure of the sediment and the quartz separation protocol at the laboratory. The obtained quartz grains have underwent different TL/OSL tests and the equivalent dose has been determined. We have evaluated the annual dose using gamma spectrometry, and a preliminary age as 1.22 ka ± 0.11 has been attributed to the sediment.
