Abstract
ESR dating is a palaeodosimetric method based on the detection and quantification of the trapped charges accumulated over time in the crystal lattice of some materials due to their exposure to natural radioactivity. Like any chronometric dating methods, ESR has strengths and weaknesses. In particular, whilst the precision achieved with ESR is not as good as that of radiometric methods (e.g. radiocarbon, Ar-Ar or U-Th), it does have the advantage to being able to be used on a wide range of materials, covering thus almost any geological contexts during the last 2.6 Ma. Amongst them, the ESR dating of fossil tooth enamel and optically bleached sedimentary quartz grains are probably the most interesting applications in archaeology. This study mainly aims at showing an updated overview of the potential -and current limitations- of the ESR dating method used in geoarcheological contexts, through a synthesis of the previous studies carried out on various sites of the Iberian Peninsula that have been published over the last 30 years.
