LUMINESCENCE DATING OF LATE QUATERNARY SEDIMENTS FROM EAST GREENLAND

Luminescence dating based on K-feldspars and using both TL and OSL methods have been performed on 94 sediment samples from East Greenland.-The ages go back more than 380 ka, but are mainly from the last interglaciation and the subsequent period and include both shallow-marine/coastal-fluvial and ice proximal meltwater sediments. Independent age control indicates that the dates in the first group generally fall within +/- 15% of the expected age, although a few samples show larger deviations. The ice proximal sediments, on the other hand, show a much larger spread and exaggerated ages, probably owing to incomplete bleaching. OSL may give better results than TL in these sediments.
