Magaliesberg
The Magaliesberg (historically also known as ''Macalisberg'' or ''Cashan Mountains'') of northern South Africa, is a modest but well-defined mountain range composed mainly of quartzites. It rises at a point south of the Pilanesberg (and the Pilanesberg National Park) to form a curved prominence that intersects suburban Pretoria before it peters out some to the east, just south of Bronkhorstspruit. The highest point of the Magaliesberg is reached at Nooitgedacht, about above sea level. A cableway reaching to the top of the mountain range is located at Hartbeespoort Dam, providing sweeping views of the Magaliesberg and surrounding area. Geology The Magaliesberg has ancient origins. Its composition is ascribed to successive geological processes over a very protracted history. Its quartzites, shales, chert and dolomite were deposited as sediments in an inland basin on top of a 3 billion year old Archaean Basement Complex, known as the Kaapvaal Craton. This process of sediment ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hartebeespoort Dam
Hartbeespoort Dam (also known as ''Harties'') is an arch type dam situated in the North West Province of South Africa. It lies in a valley to the south of the Magaliesberg mountain range and north of the Witwatersberg mountain range, about 35 kilometres north west of Johannesburg and 20 kilometres west of Pretoria. The name of the dam means "dam at the gorge of the hartebeest" (a species of antelope) in Afrikaans. This "poort" in the Magaliesberg was a popular spot for hunters, where they cornered and shot the hartebeest. The dam was originally designed for irrigation, which is currently its primary use, as well as for domestic and industrial use. The dam has suffered from a hypertrophic state since the early 1970s. Mismanagement of waste water treatment from urban zones within the Hartbeespoort Dam catchment area is largely to blame, having distorted the food web with over 280 tons of phosphate and nitrate deposits. The town of Hartbeespoort is situated close to the dam wall an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pilanesberg National Park
The Pilanesberg National Park is located north of Rustenburg in the North West Province of South Africa. The park borders on the Sun City entertainment complex. It is currently administered by the North West Parks and Tourism Board. The area lies in the root zone of an extinct volcano, and is defined by alternating ridges and valleys forming concentric rings, a geological formation that rises abruptly in the form of hills above the surrounding plains. The Pilanesberg is named for chief Pilane of the Kgafêla people, who ruled from Bogopane, Mmamodimokwana and eventually Mmasebudule during the 1800s. The 'Pilanesberg Alkaline Ring Complex' is the park's primary geological feature. This vast circular feature is geologically ancient, being the ring dikes that fed a completely eroded caldera created by volcanic eruptions some 1,200 million years ago. It is one of the largest volcanic complexes of its type in the world, the rare rock types and formations make it a unique geologic ...

Drakensberg
The Drakensberg (Afrikaans: Drakensberge, Zulu: uKhahlambha, Sotho: Maluti) is the eastern portion of the Great Escarpment, which encloses the central Southern African plateau. The Great Escarpment reaches its greatest elevation – within the border region of South Africa and Lesotho. The Drakensberg escarpment stretches for more than from the Eastern Cape Province in the South, then successively forms, in order from south to north, the border between Lesotho and the Eastern Cape and the border between Lesotho and KwaZulu-Natal Province. Thereafter it forms the border between KwaZulu-Natal and the Free State, and next as the border between KwaZulu-Natal and Mpumalanga Province. The escarpment winds north from there, through Mpumalanga, where it includes features such as the Blyde River Canyon, Three Rondavels, and God's Window. It then extends farther north to Hoedspruit in southeastern Limpopo where it is known as 'Klein Drakensberg' by the Afrikaner. From Hoedsprui ...

Highveld
The Highveld (Afrikaans: ''Hoëveld'', where ''veld'' means "field") is the portion of the South African inland plateau which has an altitude above roughly 1500 m, but below 2100 m, thus excluding the Lesotho mountain regions to the south-east of the Highveld. It is home to some of the country's most important commercial farming areas, as well as its largest concentration of metropolitan centres, especially the Gauteng conurbation, which accommodates one-third of South Africa's population. Location and description The Highveld constitutes almost the whole of the Free State, and Gauteng Provinces, and portions of the surrounding areas: the western rim of Lesotho, and portions of the Eastern Cape, Northern Cape, North West, Limpopo, and Mpumalanga Provinces of South Africa. The highest part of the Highveld, around 2100 m, is its northeastern well-defined boundary, where the plateau escarpment (the Mpumalanga Drakensberg) separates it from the Mpumalanga Lowveld, (containing, ...

Hartbeespoort Aerial Cableway
The Hartbeespoort Aerial Cableway (or Harties Cableway), originally constructed in 1973, is a 1.2 km long cableway that extends to the top of the Magaliesberg and offers panoramic views of the Magaliesberg, Hartbeespoort Dam and the surrounding area. It is situated 1 km to the north of the town of Hartbeespoort in the North West Province, and is the longest mono-cableway in Africa Africa is the world's second-largest and second-most populous continent, after Asia in both cases. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area .... In 2010 the cableway was completely revamped and modernised by Zargodox (Pty) Ltd, and officially reopened on 14 August 2010 by the then Minister of Tourism Marthinus van Schalkwyk. The aerial cableway is open seven days a week. History 1973–2005 The first Harties Aerial Cableway was constructed in 1973. The aerial cableway was a top v ...

Bushveld
The Bushveld (from af, bosveld, af, bos 'bush' and af, veld) is a tropical and subtropical grasslands, savannas, and shrublands, sub-tropical woodland ecoregion of Southern Africa. It encompasses most of Limpopo Province and a small part of the North West Province (South Africa), North West Province of South Africa, the Central and North-East Districts of Botswana and the Matabeleland South and part of the Matabeleland North provinces of Zimbabwe. Kruger National Park in South Africa has a number of 'Bushveld' camps. The terms 'bushveld' and 'lowveld' are sometimes used interchangeably, and the line between the two is somewhat blurred, although the lowveld lies in Mpumalanga. Geography The elevation of this region varies from 750 to 1,400 m and the annual rainfall ranges from 350 mm in the west to 600 mm in parts of the northeast. There are four significant mountain ranges in this region: the Magaliesberg which runs from Rustenburg in the west to Bronkhorstspruit i ...

Kaapvaal Craton
The Kaapvaal Craton (centred on Limpopo Province in South Africa), along with the Pilbara Craton of Western Australia, are the only remaining areas of pristine 3.6–2.5 Ga (billion years ago) crust on Earth. Similarities of rock records from both these cratons, especially of the overlying late Archean sequences, suggest that they were once part of the Vaalbara supercontinent. Description The Kaapvaal Craton covers an area of approximately and is joined to the Zimbabwe Craton to the north by the Limpopo Belt. To the south and west, the Kaapvaal Craton is flanked by Proterozoic orogens, and to the east by the Lebombo monocline that contains Jurassic igneous rocks associated with the break-up of Gondwana. The Kaapvaal Craton formed and stabilised between 3.7 and 2.6 Ga by the emplacement of major granitoid batholiths that thickened and stabilised the continental crust during the early stages of an arc-related magmatism and sedimentation cycle. The craton is a mixture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bushveld Igneous Complex
The Bushveld Igneous Complex (BIC) is the largest layered igneous intrusion within the Earth's crust. It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal Basin. It is approximately 2 billion years old and is divided into four different limbs: the northern, southern, eastern, and western limbs. The Bushveld Complex comprises the Rustenburg Layered suite, the Lebowa Granites and the Rooiberg Felsics, that are overlain by the Karoo sediments. The site was first discovered around 1897 by Gustaaf Molengraaff. Located in South Africa, the BIC contains some of the richest ore deposits on Earth. The complex contains the world's largest reserves of platinum-group metals (PGMs) or platinum group elements (PGEs)—platinum, palladium, osmium, iridium, rhodium, and ruthenium along with vast quantities of iron, tin, chromium, titanium and vanadium. These are used in, but not limited to, jewellery, automobiles ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Escarpment
An escarpment is a steep slope or long cliff that forms as a result of faulting or erosion and separates two relatively level areas having different elevations. The terms ''scarp'' and ''scarp face'' are often used interchangeably with ''escarpment''. Some sources differentiate the two terms, with ''escarpment'' referring to the margin between two landforms, and ''scarp'' referring to a cliff or a steep slope. In this usage an escarpment is a ridge which has a gentle slope on one side and a steep scarp on the other side. More loosely, the term ''scarp'' also describes a zone between a coastal lowland and a continental plateau which shows a marked, abrupt change in elevation caused by coastal erosion at the base of the plateau. Formation and description Scarps are generally formed by one of two processes: either by differential erosion of sedimentary rocks, or by movement of the Earth's crust at a geologic fault. The first process is the more common type: the escarpment is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
