✦ Synopsis
Abatraet--Certain materials that are capable of being dated by TL have a mixed history of their quartz content: first, not all quartz grains may have been completely zeroed at the initial instant, and secondly, their geological origin could be varied. Thus, individual TL behaviour characteristics of different quartz grains from the same sample may not all be suitable for TL dating and obviously those which are not suitable hinder the measurements for TL dating.
The present work concerns TL measurements on individual quartz grains taken one by one with the prospects of selecting, those with good TL characteristics for dating studies. A statistical study is then carded out with the results.
A case study for a volcanic event, and the possibilities for automating the measurement and data reduction are discussed. The advantage of automation lies in the exploitation of the great variability of quartz: although poor quartz (from the TL dating point of view) is often encountered, very good quartz can sometimes be found, and data processing techniques provide the ability to look for it.
