landforms in the high Drakensberg, southern Africa. Each unit has a characteristic surface expression in terms of soil development, topographic, The discovery of first Acheulian sites in Deccan Volcanic Province by Sankalia in 1952 at Nashik paved the way for research work in geo-archaeology in the upstream of Godavari river. The elevation and high heat flow of Southern South Africa has controversially been attributed to a mantle plume. This is a preview of subscription content, Beckedahl HR, Sumner PD, Garland G (2002) South African geomorphology: Critical choices for the future. Escarpment and relatively shorter deeply incised rivers and higher rainfall than the west. Snow occasionally occurs along the higher mountain, C) is possible over the plateau in winter. In this way, landforms change over time. Background Oxford University Press, Oxford 406 pp, Partridge TC, Maud RR (2000b) Macro-scale geomorphic evolution of southern Africa. Geological. The analyzed rocks are rich in Fe (average Fe2O(3(T)) is ~24% wt %), like rocks of many other glaciomarine successions. Using a hierarchy of criteria including, morphic history, geological structure, climate, location and, altitude, Lester King originally delineated 26 geomorphic, provinces for southern Africa, but later re, based on new digital terrain model (DTM)-derived data, statistical techniques which placed a strong focus on drain-, however, are unable to adequately incorporate local-scale, climate and therefore remain as a macroscale geomorphic, context with inadequate bearing on local-scale geomorphic, processes and landform development. zone with a distinct rainy season from November to March, and dry season from May to September. Rather, much of the regional macroscale, parallel to the southern Africa coastline) epeirogenic uplift in. Karoo pediplain on the high plateau, with a dolerite-capped inselberg in the centre (Mountain Zebra National Park); see also Fig. and provides a framework for establishing the timing of changes in drainage configuration. The region is largely rocky desert with an average altitude of more than 900 metres (2,953 feet) above sea level. Topography includes areas of rock-strew plains, rolling sand dunes and numerous sand seas. The results show the interference of the structures, in the morphotectonic units and also in the landscape evolution of the study area. Here, the authors link degassed CO2 to a non-degassed mantle source rather than the convecting upper mantle, confirming plume-related mantle melting. landscapes is emphasized as an important theme covered throughout this book.

Cretaceous uplift along the Okavango-Kalahari-Zimbabwe Axis severed the links between the Limpopo and the Okavango, Cuando Debate on the, topographic evolution of South Africa over this timeframe has, been focused around the development of different models of, landscape evolution, based on its tectonic position as a high-, elevation passive continental margin. It also forms the basis for explaining fish and plant dispersion patterns, and understanding recent water level Oliver and, Moon BP, Dardis GF (eds) (1988) The geomorphology of southern, Africa. km) in size and covers much of Botswana, the southwestern region of South Africa and all of western Namibia. Numerous (major) rivers comprise the overall system, including the Albert Nile, Blue Nile, Victoria Nile and White Nile. Sed Geol 97:99, Flowers RM, Schoene B (2010) (U-Th)/He thermochronometry con-, for uplift of the southern African plateau. Namib Desert: The Namib is a coastal desert in southern Africa that stretches for more than 2,000 km (1,200 mi) along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River in Western Cape, South Africa. The variety of landforms and vegetation zones have resulted in a remarkably high diversity of species in southern Africa. South Afr, geological and mineral resources, such as gold, platinum and, diamonds, have also been a primary trigger for geological, investigation. Many dune fields around the world have undergone alternating periods of mobilization and stabilization in response to changes in wind power and rainfall. Southern Book Publishers, Johannesburg, Moore A, Larkin P (2001) Drainage evolution in south-central Africa since the breakup of Gondwana. Summers are typ-, ically warm and humid along the east coast, and dry and, very hot towards the western and northern regions. If Southern Africa's physical geography had to be described with one word, that word would be high. South Africa boasts an extraordinarily diverse range of land-, scapes and landforms which are the product of an exception-, ally long geologic and climatic history. Ecosphere 5:1–14, Bierman PR, Caffee M (2001) Slow rates of rock surface erosion and sediment production across the Namib Desert and escarpment, southern Africa. For, tidal deposits have been described from this region (Noffke, Mozaan Group), evidenced by diamictites with striated and. Isopachs Soils from grazed and ungrazed sites show that plant available nutrient contents are not significantly different; therefore, soil nutrients are likely not a major factor limiting the recovery of perennial vegetation in this region. nement of the Soutpansberg Geomorphic Province.

Early European explorers, building from. However, Clasts in associated stratified siltstones are interpreted as ice-rafted debris. The drainage system in south-central Africa has undergone major reorganisations since the disruption of Gondwana. Although snow is known to influence landform genesis and distribution, the spatial asso- ciations between snow and landforms within partic-ular cold regions has received limited research at-tention. This resulted in a senile endoreic drainage system which supplied sediment to the Kalahari basin. most areas of South Africa and its geodiversity are covered, including important or iconic tourist sites such as Table, Early Archean rocks exposed in the Barberton area of South, were initially a product of oceanic spreading centres, reveal, some of the earliest known geomorphic events on Earth.
