Future directions of luminescence dating of quartz

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.Feldspars have the specificity of being sensitive both to short and to near-infrared or infrared wavelength (800-950 nm; Bøtter-Jensen ., 1994); iv) the sensitivity of the trap to light.Released electrons can recombine with another kind of crystalline defects (“holes” reflecting electrons vacancies).

The main minerals studied are quartz and K-rich feldspar, which can be found in almost all sedimentary environments.

This phenomenon is associated with a resetting (“zeroing”) of the dosimetric clock; iii) after one or several transport phases the grain is “definitively” buried under a sedimentary cover.

It is exposed again to radiation and accumulates trapped electrons.

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.

  1. You probably have stories that could compare, LOL.**Make sure you’ve actually leafed through this book; otherwise, substitute the last 2 sentences with a question about something you read in her profile.**May the odds be ever in your favor…
