Geography of Africa
An assessment of the changing map of sub-saharan Africa, explaining the role of the domino theory in decolonization, the buffer zone in Southern Africa, and intensification of contrasts between core and periphery in SouthAfrica. Trends toward
devolution in many countries suggest that changes in Africa's political framework will accelerate. - (DWG)
Holocene ecology and prehistory in the Egyptian Sahara in The Sahara and the Nile. Quaternary environments and prehistoric occupation in northern Africa.
The AA. studied samples of dust and topsoils in various agroecological zones, from the north to the south of Ghana, focussing mainly on the mineralogy of these materials. Some data about grain sizes and morphology of the samples are also presented
. The relative contents of K-feldspars and plagioclase vary markedly in the different zones. The pH of the dust is significantly higher than that of the local soils, indicating that a substantial amount of the dust comes from the Sahara.
In this paper reflections on the development of scarpfoot depressions are presented from a geomorphologic-geological, and sedimentological point of view. They are intended to clarify whether post-sedimentary relief development in Central Sahara

ferrimagnetic mineral (magnetite/maghemite) concentrations, with samples south of the Sahara/Sahel transition, generally containing greater concentrations than dusts from further north where the climate is much drier. This distinction is seen especially clearly
The mineral magnetic properties of deposited dusts collected along a broadly north-to-south transect across Niger have been investigated on both a bulk and particle size-specific basis. Dusts display a general north-to-south gradient in fine-grained
