Luminescence dating techniques

"Optical dating" typically refers to OSL and IRSL, but not TL.

All sediments and soils contain trace amounts of radioactive isotopes of elements such as potassium, uranium, thorium, and rubidium.

It includes techniques such as optically stimulated luminescence (OSL), infrared stimulated luminescence (IRSL), and thermoluminescence dating (TL)., (1)Department of Agronomy, University of Cordoba, Cordoba, Spain, (2)Applied Physic, University of Cordoba, Cordoba, Spain, (3)Soil Geography and Landscape group & Netherlands Centre for Luminescence dating, Universidad de Wageningen., Wageningen, Netherlands, (4)Rural Engineering, Universidad de Córdoba, Cordoba, Spain, (5)Netherlands Centre for Luminescence dating (NCL), Delft University of Technology, Netherlands, (6)University of Cordoba, [email protected] formation includes important factors such as bioturbation and erosion-deposition.These geomorphological processes alter the soil properties and the soil production from saprolite.Consultation with a lab prior to field work will also help avoid collection of non-ideal/ unsuitable material, submittal of incomplete samples, or missing information required for dating.Luminescence specialists are available to help assess the specific luminescence technique, grain size and mineral fraction needed to produce the most accurate age results from each setting. S.-based laboratories operate under standard protocols like optically stimulated luminescence (OSL) of quartz, and/or infrared stimulated luminescence (IRSL) of feldspar, and some specialize in other capabilities like single-grain and/or fine-grain dating, pulsed luminescence, and/or thermal transfer OSL.
