Stability of some centres in quartz

(1991)

Electron spin resonance (ESR) is a promising dating method for Quaternary sediments. A preliminary 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 (Al 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
