Après une présentation des principes physiques généraux, les procédures mises en œuvre aussi bien sur le terrain qu’en laboratoire sont abordées, à partir de l’exemple des analyses réalisées sur des alluvions sableuses issues d’une basse terrasse de la Moselle.La place des datations OSL dans la recherche géomorphologique en France et son potentiel pour les recherches futures sont décrits à travers une présentation de la diversité des environnements sédimentaires et des problématiques pouvant être traités.Strata Data offers a dating service using the Optically Stimulated Luminescence (OSL) technique.This is done in collaboration with the University of Oxford Luminescence Dating Laboratory.The basic cost is £550/sample plus reporting time based on your requirements.The report will contain OSL results calibrated for sample water content and salinity.Stimulating samples using infrared light causes luminescence, the intensity of which varies depending on the amount of radiation absorbed.Exposure to sunlight resets the luminescent signature and so the time period since the sediment was buried can be calculated.

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.

The potential of red thermoluminescence (RTL) emission from quartz, as a dosimeter for baked sediments and volcanic deposits, has received some attention over the past decade.

While there have been some important observations relating to signal stability, saturation characteristics and emission wavebands, there has not been a systematic analysis of RTL properties of older (i.e., 1 Ma), quartz-bearing known age volcanic deposits.

Turnaround time is several weeks to several months and very dependent on the time taken to prepare the samples, with organic rich samples taking the longest. All sediments contain trace minerals including uranium, thorium and potassium.
