Untitled Page 1 Page 2 GEOMORPHOLOGY OF DESERT DUNES Sand dunes cover up to a quarter of many desert regions. Determining the factors that determine their shape, size and …
Sediment in coastal N amibia to southern Angola is supplied dominantly from the Orange River with minor additional fluvial input and negligible modifications by chemical processes …
This is the first-ever regional study of the geomorphology of the world's deserts, demonstrating why different deserts have special landscape features and land-forming …
The sedimentary record of aeolian sand systems extends from the A rchean to the Q uaternary, yet current understanding of aeolian sedimentary processes and product remains …
Optically stimulated luminescence (OSL) dating of dune deposits has increasingly been used as a tool to investigate the response of aeolian systems to environmental change …
Ground penetrating radar (GPR) profiles across a complex linear dune in the Namib Sand Sea have been used to image sets of cross-stratification and their bounding surfaces. A …
Wet aeolian systems, in which the water table or its capillary fringe are in contact with the accumulation surface, such that moisture influences sedimentation, are well‐known from …
In this paper, we review ideas on the geomorphological history of the southwest African passive margin, focusing on the central Namib sector and presenting new evidence on the …
Quantitative provenance analysis based on high-resolution bulk-petrography and heavy- mineral data on beach and dune sands, integrated with detrital-zircon geochronology and …
