HYDROLOGIE VAN DE PINGO 'VAGEVUUR' (NIETAP, DR.) IN HET LAAT-GLACIAAL EN VROEG-HOLOCEEN
Samenvatting
The occurrence of tree stubs in a pingo scar known as 'Vagevuur' in the north of the province of Drenthe, the Netherlands, is discussed. The stubs are largely submersed with only the uppermost part emerging from the water. A wood sample of one of the stubs appears to belong to Scotch pine (Pinus sylvestris) and has been radiocarbon dated to the early 8th millennium (7900±30 BP). The distribution of the stubs displays an oval pattern, which suggests that the trees grew along the edge of a former bog or pool. This provides evidence about the shape and extent of the pool at the start of the 8th millennium. The small size of the pool indicates a dry elimate in this period. The chronostratigraphical, sedimentary and palynological evidence obtained from several corings indicates that the area covered by water measured c. 100 m in diameter during the Younger Dryas.
