Pilanesberg
The Pilanesberg (formerly Pilandsberg) is a mountain in the North West Province, South Africa. The mountain is an ancient volcanic structure, circular in shape, that rises from flat surrounding plains. It is formed by three concentric ridges or rings of hills, of which the outermost has a diameter of about 24 km. The Pilanesberg is located 100 km to the North-West of Pretoria and is for the greater part enclosed in a protected area known as Pilanesberg National Park. The Elands River flows South of the Pilanesberg in an Easterly direction. There are a number of platinum mines right at the perimeter of the crater formation. The name "Pilanes" comes from a historic Tswana chief named Pilane. Geology Although geographically located within the Witwatersrand range, the mountain is geologically part of a feature known as the ''Pilanesberg Alkaline Ring Complex''. It is a vast ring dike of a very ancient extinct volcano that last erupted some 1,200 million years ago. The ... [...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 ...

Sun City (South Africa)
Sun City is a luxury resort and casino, situated in the North West Province of South Africa. It is located between the Elands River and the Pilanesberg, about 140 km northwest of Johannesburg, near the city of Rustenburg. The complex borders the Pilanesberg National Park. It is made up of a number of themed sub-resorts with hotels on each, including the original Sun City Resort, ''The Cabanas'', ''The Cascades'' and the ''Lost City'' (The Palace). History Beginning Sun City was developed by the hotel magnate Sol Kerzner as part of his Sun International group of properties. It was officially opened on 7 December 1979, then located in the Bantustan of Bophuthatswana. As Bophuthatswana had been declared an independent state by South Africa's apartheid government (although unrecognised as such by any other country), it could provide entertainment such as gambling and topless revue shows, which were banned in South Africa. Those factors, as well as its relatively clos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Mountains In South Africa
List of Mountains in South Africa, Lesotho and Eswatini is a general list of mountains in South Africa, Lesotho and Eswatini with elevation. This list includes mountains in two other sovereign states, in the Stormberg- Drakensberg range, where the highest elevations are to be found in Lesotho, as well as Emlembe, the highest mountain in Eswatini, located at the border with South Africa. The highest mountain in South Africa is high Mafadi, located on the border of South Africa and Lesotho. Several of the highest peaks have snow in the Southern hemisphere winter season. A ''Khulu'' is a peak above and not within of another ''Khulu'', as defined by the Mountain Club of South Africa. Seweweekspoortpiek and Du Toits Peak are among the ultra prominent peaks of Africa. A few mountains, such as Spion Kop or Isandlwana are historically important hills, even though they are relatively not very high. Table Mountain is important because of its emblematic flatness.

Witwatersrand
The Witwatersrand () (locally the Rand or, less commonly, the Reef) is a , north-facing scarp in South Africa. It consists of a hard, erosion-resistant quartzite metamorphic rock, over which several north-flowing rivers form waterfalls, which account for the name Witwatersrand, meaning "white water ridge" in Afrikaans.Truswell, J.F. (1977). ''The Geological Evolution of South Africa''. pp. 21, 27–28, 33–36. Cape Town: Purnell. This east-west-running scarp can be traced with only one short gap, from Bedfordview (about west of O.R. Tambo International Airport) in the east, through Johannesburg and Roodepoort, to Krugersdorp in the west (see the diagram at left below).Norman, N.; Whitfield, G. (2006) ''Geological Journeys''. pp. 38–49, 60–61. Cape Town: Struik Publishers. The scarp forms the northern edge of a plateau (or ridge) which rises about above the surrounding plains of the Highveld. A number of picturesque Johannesburg suburbs, including Observatory, ...

Vaalkop Dam
The Vaalkop Dam is a combined gravity and earth-fill type dam located in North West Province, South Africa. Its reservoir is located at the confluence of the Elands River and the Hex River, part of the Crocodile basin. The dam was established originally in 1972 and was renovated in 2008 in order to supply water for the platinum and associated metals mining operations in the area. The dam mainly serves for irrigation purposes, municipal water supply and industrial uses. The hazard potential of the dam has been ranked high. The Vaalkop Dam lies near Pilanesberg, ESE from the outer perimeter of the ancient crater formation.

Ring Dike
A ring dike or ring dyke is an intrusive igneous body that is circular, oval or arcuate in plan and has steep contacts. While the widths of ring dikes differ, they can be up to several thousand meters. The most commonly accepted method of ring dike formation is directly related to collapse calderas.Gudmundsson, Agust. "Formation of collapse calderas." ''Geology'' 16.9 (1988): 808–10. Caldera collapse and ring dike formation Collapse calderas form due to the emptying of a magma chamber. Effusive eruptions that take place on the flanks of the associated volcano and a fissure system that direct magma away from the chamber are both mechanisms that can empty a magma chamber. As pressure in the magma chamber changes, an increase in tensile stresses create tension fractures at the surface of the volcano. The geometry of the top of the magma chamber dictates the location and magnitude of the tension fractures. In addition, it was found that the higher the radius to depth ratio of the ...

NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown m ...

Geology
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of ...

Mountains Of South Africa
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable ...

Landforms Of North West (South African Province)
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features.
