We report here a new application of thermoluminescence (TL) for dating sand dunes. This application assumes that exposure to sunlight causes bleaching of the geological TL of a sediment to a residual value and that TL accumulation starts again when the sediment is buried under fresh deposit and is thus shielded from the Sun. Although the TL method has been applied to loess and ocean sediments, the application of this technique to sand dunes provides the first reliable dating control for dune dynamics, palaeoclimatology and spread of deserts.
