In this work, the equivalent dose values have been determined using the standard multiple- and single- aliquots process for the geological sample and the infrared stimulated luminescence decay curves were decomposed into fast, medium and slow components using a simple fitting procedure. The Equivalent dose (ED) values were recalculated using these components and the results were compared in between. The ED obtained using the slow components displays comparable results with those obtained by standard methods.

    The author collected 26 samples from six loess profiles located in Poland and Ukraine and 16 samples from three galcigenic profiles in Lithuania. TL and OSL dates were obtained for the samples. The TL dates were calculated in the Gdañsk University laboratory and the OSL dates were obtained by...

    Ripple-laminated sandy deposits at shallow water depths in four rivers on Jameson Land, East Greenland were sampled for optically stimulated luminescence (OSL) dating. Silt-sized grains have significantly higher equivalent doses (~1.1 Gy) than sand grains (~0.1 Gy). This suggests that coarse...

    This study examines the effects of feldspar contamination of different extent (by fluorosilicic acid etching for different time periods and mixing pure quartz with different percentage of unetched grains) on blue-light stimulated luminescence (BLSL) of quartz (38-63 µm) for Chinese loess. In...

    In the dating of sediments by luminescence methods, to obtain a sample the purest possible as to its mineralogy determines the rest of the analytical procedures. The isolation of the sample minerals is a critical stage due to the impossibility of quantifying the relative contributions to the...
