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