This paper aims to provide an overview concerning the optically stimulated luminescence (OSL) dating method and its applications for geomorphological research in France.

An outline of the general physical principles of luminescence dating is given.

Hence it underlines the increasing importance of the method to geomorphological research, especially by contributing to the development of quantitative geomorphology.

L’objectif de cet article est de proposer une présentation d’ensemble des méthodes de datations par luminescence stimulée optiquement (OSL) et de leurs applications dans le champ des recherches en géomorphologie.

Ainsi, l’article souligne l’importance de la méthode pour les recherches en géomorphologie, notamment dans le cadre du développement de la géomorphologie quantitative.

Absolute dating methods have been developed over the last five decades (Jull and Scott, 2007).

The method is a direct dating technique, meaning that the amount of energy emitted is a direct result of the event being measured.

If we assume that the radiation dose rate of the sediment has remained constant over time, then if we measure that dose rate, we can calculate the sample age.

Hollie Wynne (Aberystwyth University) stirs OSL samples being treated with acid in the preparation lab of the Aberystwyth Luminescence Research Laboratory. We make an approximation of the number of trapped electrons by measuring the light that they emit following stimulation by light (hence the name of the technique, “Optically stimulated luminescence”).

Despite the progress toward understanding the chronological and spatial aspects of the wheels, a great deal of research remains to resolve the actual nature of these enigmatic stone structures.

Optically stimulated luminescence is a method of determining the age of burial of quartz or feldspar bearing sediments based upon principles of radiation and excitation within crystal lattices, and stems from the fact that imperfections in a crystal lattice have the ability to store ionizing energy (Radiation is absorbed by the crystal lattice upon sediment burial, and over time, excites electrons causing them to migrate within the crystal and become stored in traps resulting from crystal lattice defects.
