Optically Stimulated Luminescence (OSL) Dating of Quaternary Deposits from the Sussex/Hampshire Coastal Corridor

Author(s): Bates, M R, Rebecca Briant, E J Rhodes, Jean-Luc Schwenninger, Francis Wenban-Smith

A total of 43 samples were collected from different sites across the West Sussex coastal plain, the Western and Eastern Solent, the Test Valley, and the Isle of Wight for optically stimulated luminescence (OSL) dating. The dates were obtained from sand-sized quartz grains, and alaeodose determinations were made using a single aliquot regenerative-dose (SAR) protocol. The environmental dose rate for each sample was calculated using the results of neutron activation analysis (NAA) and in situ gamma-ray spectroscopy measurements. The concentrations of radioactive elements were nearly always above detection limits and the samples and their luminescence characteristics were generally considered to be suited for OSL dating.
