Luminescence methods (TL and OSL) are based on the estimation of the impact of radiation on the crystalline structure of minerals while they are shielded from light (Aitken, 1985; Wintle, 1997; Aitken, 1998; Duller, 2004; Vandenberghe, 2004).For the investigated coarse grain quartz samples all ages calculated from the MAM-3UL, including their uncertainties, are within the historical documented age.Results of the polymineral fine grain samples are overestimating the historically documented depositional age, indicating undetectable incomplete bleaching.Most of the publications actually focus on one part of either the method (, laboratory procedures, statistical treatment) or its applications, and available general literature for non-specialists is still uncommon.The general principles of the method are described first.
