Sedimentological examination of the sediments in the area along the northern margin of the loess belt in Northern Germany show a typical stratigraphic sequence of at least five phases of aeolian sedimentation. As a contribution to the chronostratigraphic classification of the sedimentary sequence in this zone, 15 samples from a section close to Denstorf, near Braunschweig in Lower Saxony, Northern Germany, were dated, using thermoluminescence (TL) as well as optically stimulated luminescence (OSL). The age estimates obtained by dating the potassium-rich feldspars and quartz-rich extracts lead to the assumption that the northernmost Last Glacial loess accumulation occurred during the Late Glacial period. This confirms earlier suggestions that the northernmost loess deposits in Northern Germany represent the return of strong aeolian processes under the cold and dry conditions of the Late Glacial.
