While a crystalline material is heated from room temperature to around 500°C, a weak but measurable light will be emitted. This light is known as thermoluminescence (TL) and is based on storage of energy from ionizing radiation in many naturally occurring TL minerals, including quartz and feldspar. The source of radiation is the radioactive materials such as uranium, thorium, potassium and cosm...

We have investigated an optically stimulated luminescence (OSL) dating study in the Nimbluk lakebed in Khorasan, northeast Iran. Two samples of the lake-bed sediments from ~1 m below the land surface are successfully dated at 7.3-9.9 ka. All necessary experiments have been performed to choose the most suitable procedure for dating quartz extracts using single aliquot regeneration method (SAR). ...
