Abstract

A well-defined thermoluminescence (TL) peak was observed in several quartz samples from various origins in the range 380–395°C (heating rate 5°C s -1 ) at a wavelength of around 600–620 nm. This red TL peak (RTL), seemingly common in quartz, could be used for dating in the range 10–150 ka, and probably beyond, so a comprehensive study of its main properties seemed worthwhile. Our study included annealing and heat treatment effects, dose rate effects and fading tests. Preliminary results are also given on crushing effects and light exposure sensitivity.

Abstract

Electron spin resonance (ESR) is a promising dating method for Quaternary sediments. A prelimenary ESR analysis was done on quartz grains extracted from sediments baked by lava-flows of Massif Central (France). For this type of sample, zeroing occurs during heating. To test the reliability of the method, the palaeodoses were determined from centres (A1 and Ti) and compared with those obtained by the thermoluminescence (TL) method. The annealing temperature and sunlight have an effect upon the stability and the behaviour of the different ESR signals. An attempt to correlate ESR signals and the red TL peak is made in terms of the variation of these two factors.
