- Fossil pollen of the upper 30 m of a core with a length of 162 m taken near the shore of Lake Abiyata in the Ethiopian Rift Valley has been analysed. The results are compared with surface pollen spectra of different vegetation types. The sequence
- . The pedogenetic processes currently operative in the area favour decalcification and possibly silicification rather than significant near-surface calcrete formation.
- occur on near-level terrain (midslopes and footslopes) with slopes rarely exceeding 5 %. There is good evidence that in a specific landscape, dorbanks always occur in the older parts. Investigations so far also indicate that most dorbanks of the arid
- nearer to the modern lake. A large pyroclastic flow swept into northern Malawi from the Rungwe area just over 11 000 300 yr BP. An ash layer in the sediments flooring Lake Tanganyika, dated at 11 690 300 yr BP, may be the air-fall equivalent of the same
