Luminescence dating: methods, recent developments and applications

Guillaume Guérin's seminar, 2019

Abstract

Luminescence dating methods rely on the ability of certain ubiquitous minerals (quartz, feldspars) on the surface of the earth to record the radiation doses to which they are subjected. The most common applications are geomorphology to study sediment erosion, transport and deposition.
My recent research has led me to develop models of Bayesian analysis of luminescence dating in order to improve its accuracy and accuracy. In addition, luminescence has recently made it possible to date the surface exposure of rocks to light, or to work in low-temperature thermochronometry. Regarding the applications of luminescence, I worked in recent years mainly on the prehistory of Western Europe, including studies of Breton sites (Menez Dregan, Beg-er-Vil, Béniguet, etc.).
During this presentation, I will present the methods, some applications and an overview of recent developments in the field. I will also say a few words about the ERC project (Starting Grant 2019), which I am carrying and which concerns the Neanderthals, who passed the first stage of selection and that I will go to defend orally at the end of the month. next June.
