The Plateau Method For Dating Partially Bleached Sediments By Thermo-Luminescence

The plateau method for dating sediments that have been incompletely bleached prior to deposition is described. By exposing aliquots of a sample to sunlight for different periods of time, a range of residual values is obtained and combined with the additive dose or the regeneration technique to yield a series of paleodoses. The correct paleodose is taken as that for which the longest plateau in a plot of paleodose vs. temperature is obtained.
