Optical dating of sediments

The trapped charge accumulates over time at a rate determined by the amount of background radiation at the location where the sample was buried.

The radiation causes charge to remain within the grains in structurally unstable "electron traps".

It uses various methods to stimulate and measure luminescence.

It includes techniques such as optically stimulated luminescence (OSL), infrared stimulated luminescence (IRSL), and thermoluminescence dating (TL).

Although there is stratigraphic correlation based on archaeological finds of Ahmarian origin, numerical age estimates are lacking.

We applied single-aliquot optical dating of coarse grained quartz of wadi deposits and investigated the luminescence properties in detail to achieve more accurate age information about the time of human occupation.

Extreme concentrations of boron result in economic evaporitic deposits, and, thus, water-soluble boron minerals, notably borax, have been among the most accessible of useful compounds to humankind, even in antiquity.

At Wadi Sabra (SW Jordan) human occupation dates back to the Palaeolithic and Epipalaeolithic.

Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating.
