摘要
Thermoluminescence (TL) signals from suspended sediment in an Icelandic meltwater stream exhibit small-scale random fluctuations over time, but show sufficient consistency to indicate that larger-scale fluctuations in TL are systematic rather than random. It is concluded that diurnal TL fluctuations are related to changes in sediment source and ambient conditions during transport. The results suggest 'young' fluvioglacial sediments may prove difficult to date using standard TL techniques.
