The fadia method: a new approach in luminescence dating using the analysis of single feldspar grains

The fadia method has been recently introduced in luminescence as one that may potentially resolve the problem of anomalous fading and age shortfalls in IRSL dating of sediments. This method takes advantage of the differential fading rates of single feldspar grains and allows one to extrapolate to zero fading. This paper describes step by step the protocol used in the Montréal laboratory. The application of the method is shown to be hampered by the occurrence of faintly luminescent feldspar minerals, and/or unbleached grains in the dated sediment samples.
