We investigate the feasibility of a modified single-aliquot regenerative-dose (SAR) protocol for OSL dating of individual grains from young samples (<300 years) using dose-recovery tests. Parameters such as pre-heat temperature, test- and regenerative-dose size, an additional bleaching step at high-temperature and optical stimulation time are optimised to give the highest percentage of accepted...
Two modern coastal sands are studied through single-grain optical dating techniques. The first sample is estimated to be less than 10y old by means of independent age control and is known to be well-bleached on the basis of preliminary single-aliquot studies. The second sample is less than 1y old, but an age of 73±24 years had been determined through single-aliquot analysis. For both samples we compare...
