On the age of the artefact-bearing sediments partly infilling the broad valley north of Kerbehuk, Sperrgebiet, Namibia
Résumé
Understanding the geomorphological history of the Sperrgebiet is important for the mining industry because the diamond-bearing ore is of alluvial affinities. The timing of geological and geomorphological events in the Sperrgebiet has been largely based on palaeontological evidence, supported by a few radio-isotopic age determinations made on volcanic rocks but recently, archaeological evidence has been discovered that led to modifications of some of the previously proposed stratigraphic schemes. We here report an occurrence of artefact-bearing deposits partly infilling a broad valley 8 km north of Kerbehuk, which provides evidence concerning late stages of landscape development in the region.
