- Late Pleistocene and Holocene lake level fluctuations in the Lake Bogoria bassin, northern Kenya Rift Valley in Palaeoecology of Africa and the surrounding islands-Vol 13.
- Lake Bogoria is a closed-basin, saline alkaline lake in the Kenya Rift Valley. The sedimentology and mineralogy of three long drill-cores from the lake floor, and the marginal fluvio-deltaic and littoral deposite are studied here. During the late
- Pleistocene, the lake fluctuated but was mostly low and saline (anoxic)| calcrete, dolocrete and pedogenic zeolites developed in marginal soils. Following this dry phase, a regional increase in humidity during the terminal Pleistocene and early Holocene, led
- to a marked rise in lake level. The lake waters were considerably fresher than today allowing expansion of both fauna and flora, and may periodically have overflowed northwards into the Baringo sub-basin. Further fluctuations occured throughout the Holocene
- Late Quaternary history of Lake Besaka, Ethiopa in Palaeoecology of Africa and the surrounding islands-Vol 13.
- Lake Besaka, as a groundwater-fed lake which appears to have overflowed eastwards into the Awash during the late Pleistocene and perhaps again during the earliest Holocene, is not a sensitive indicator of climatic change. Only two major
- transgressions are so far evident in the late Quaternary depositional record of the lake, one dated to about 11,000-12,000 BP, the other perhaps 10,000 years older. Tectonic and volcanic factors have undoubtedly modulated the response of Lake Besaka to climatic

- A further 12 species of tree brave been identified from leaf fossils preserved in terminal Pleistocene-early Holocene lacustrine sediments exposed above the present shore of Lake Bosumtwi. Our earlier finding has been confirmed that forest
- Paleolimnological research at Lake Turkana, Kenya in Palaeoecology of Africa and the surrounding islands-Vol 13.
- A detailed account is presented of the sediments and diatoms of the Middle Pleistocene Olorgesailie Formation. Facies distributions suggest a lake that was centred on the Koora Graben and which periodically expanded over an area to the north of Mt
- Olorgesailie. The mineralogy and provenance of the sediments are discussed. The stratigraphic distribution of diatom associations suggest many lake level fluctuations. Alkalinities varied between about 5 and 85 meq/l. Based on alkalinity changes, three main
- Faunal and floral remains, changing lake levels, and a series of 15 radiocarbon dates from south-central Mauritania document climatic changes in the period c. 4500 to 2300 BP and provide the basis for estimation of mean annual precipitation greater
