Investigating the last deglaciation of the Scandinavian Ice Sheet in southwest Sweden with Be-10 exposure dating
In this study we have obtained 17 cosmogenic exposure ages from three well-developed moraine systems - Halland Coastal Moraines (HCM), Goteborg Moraine (GM) and Levene Moraine (LM) - which were formed during the last deglaciation in southwest Sweden by the Scandinavian Ice Sheet (SIS). The inferred...

In this study we have obtained 17 cosmogenic exposure ages from three well-developed moraine systems - Halland Coastal Moraines (HCM), Goteborg Moraine (GM) and Levene Moraine (LM) - which were formed during the last deglaciation in southwest Sweden by the Scandinavian Ice Sheet (SIS).
