Abstract: |
Five optically stimulated luminescence (OSL) samples were taken from the palaeochannel deposits located in the Water Meadows south of Silbury Hill, Wiltshire. The depositional nature of the sediments sampled requires coarse (ie sand-sized) grains to be used for OSL dating, to ensure that the De distribution can be examined and hence that an assessment can be made of whether the sediments were incompletely bleached at deposition. However, the palaeochannel sediments were all heavily dominated by clay. The coarsest of the five OSL samples taken was therefore selected to investigate the feasibility of isolating sufficient pure coarse-grained quartz for OSL dating from these clayrich samples. Only 0.02% of the initial very large [~1kg] initial sample mass was found to be coarse-grained quartz of between 90-250μm diameter. Nevertheless, the luminescence characteristics of this material indicated that this coarse-grained quartz was suitable for dating using small aliquots. |
