In the fine-grained lower part of the YCII unit an initial soil testifies to a decadal to centennial period of landscape stability. During the Younger Dryas, low aeolian dunes were formed locally (YCII), as a response to landscape instability due to cooling and vegetation decline. The well-developed Usselo Soil was formed during a phase of landscape stability during the late Allerød interstadial and onset of the Younger Dryas stadial. ![]() ![]() The upper part of the YCI unit was dated to the early Late Glacial. Fourteen optically stimulated luminescence dates on quartz and three radiocarbon dates provide the age control of the aeolian deposition (coversands, drift sand), landscape stability (soils) and human occupation. The exposure revealed a stacked sequence of aeolian sand units and intercalated soils (Older Coversand II, Younger Coversand I (YCI), Usselo Soil, Younger Coversand II (YCII), Holocene podzol, drift sand). ![]() The lithostratigraphy, age and human occupation of the Late Glacial and Holocene aeolian succession of a Late Palaeolithic Ahrensburg site in the excavation Geldrop-A2 (municipality of Heeze-Leende) have been investigated.
