Known commonly as Wits University, its mission is to uphold liberty of inquiry and the continuing pursuit of knowledge and truth. Gold is found in the conglomerate strata of the younger members of the Supergroup, locally referred to as banket. Wits is known for its work in deep level mining, science, health sciences, accountancy, law, governance, and the humanities, amongst others. The diamonds have been studied by researchers and reveal secrets of how the Earth worked more than 3.5 billion years ago. [7] Gold mining in these buried portions of the Witwatersrand Supergroup is sometimes carried out at depths of 4 kilometres (2.5 mi) below the surface.[6][8]. [6] Its size and position relative to Southern Africa today are indicated in the diagram on the left. The University of the Witwatersrand, Johannesburg, also known as Wits University is a leading, internationally-ranked, research-intensive University located in Johannesburg, South Africa, the economic heartland of Africa. It is the source of over 40% of the gold extracted from the Earth. The Witwatersrand Gold Rush was a gold rush in 1886 that led to the establishment of Johannesburg, South Africa. Weidenfeld and Nicolson, London. The war continued for years through, is part of the “golden arc,” an ancient inland lake containing rich deposits of, (60 miles) long and 3.6 kilometers (12,000 feet) deep in certain places. [2] This heralded the historic Witwatersrand Gold Rush. [14], Apart from the obvious hollowing out of the rocks below southern Johannesburg, causing unpredictable sinkholes, surface instabilities and earth tremors,[15] the bringing to the surface of rocks that had been laid down in oxygen-free conditions had unforeseen effects. [10] The oxygen these microorganisms produced rapidly reacted with, amongst others, any dissolved iron compounds in the water, producing insoluble red iron oxide (rust), which precipitated out during the daylight hours. His brother Thomas was the first chairman. [1] Harrison had stumbled on the Main Reef conglomerate (part of the “Johannesburg Subgroup” of rocks — see illustration above). The area is famous for being the source of 40% of the gold ever mined from the earth. Stanley, S.M. We invite you to view our full selection of sapphires, blue sapphire rings and custom sapphire jewelry and discover what makes the Natural Sapphire Company the world's greatest collection of natural sapphires. The “West Rand Group” and “Central Rand Group” of rocks together form the “Witwatersrand Supergroup”, the full horizontal extent of which is termed the Witwatersrand Basin.[2][6][1]. We offer a vast selection of blue sapphires, pink sapphires, yellow sapphires, white sapphires and other unique natural sapphires.

Sri Lanka, Hours Available Geological map of South Africa, Lesotho and Swaziland (1970). The University of the Witwatersrand Undergraduate Application Form 2022/2023 and postgraduate Admission Application Form 2022/2023 has been released online. [2] It is more commonly known as Wits University or Wits (/vəts/ or /vɪts/). The scarp forms the northern edge of a 7-to-10-kilometre-wide (4–6 mi) plateau (or ridge) which rises about 200 m (660 ft) above the surrounding plains of the Highveld. The gold was in its free elemental form. The Boer farmers denied these “uitlanders” voting rights and mounted heavy taxes on the gold industry. 81–160. It houses five faculties which comprise 34 schools. [1][6] The gold-bearing conglomerates occur chiefly in the upper, younger layers of the Witwatersrand Supergroup of rocks, on the southern side of the Witwatersrand plateau. Demuvawatha, Ratnapura Adam Mahomed Habib (born 1965) is a South African professor of political geography, incoming director of the School of Oriental and African Studies, University of London as of 1 January 2021, and the former Vice-Chancellor and Principal of the University of the Witwatersrand (Wits) in Johannesburg, South Africa. Not all the conglomerates contain gold, and of those that do (known as “reefs” by the miners), the gold is not uniformly distributed throughout the layer, but tends to occur in streaks, where the pebbles that make up the conglomerate are larger than elsewhere. It was a key part of the Mineral Revolution As with the California Gold Rush, the Witwatersrand Gold Rush had extensive social and political implications. Freeman and Company, New York. (1996). It is also the reason behind the South African currency gaining the moniker of “Rand” in 1961. It is this area in which the main gold reserves, the lifeblood of the province, are found. [9], The Witwatersrand basin was created during the Archean Eon, and is therefore amongst the oldest geological structures on earth. It is the source of over 40% of the. The basin is famous for its very large deposits of gold and uranium that occur as detrital minerals in conglomerates. Prominent graduates from University of the Witwatersrand include celebrities, politicians, business people, athletes and more. Afrikaner commandos during the Second Boer War (1899–1902). The conglomerate was quickly traced east and westward for a total continuous distance of 50 km (31 mi) to define what became known as the “Central Rand Gold Field”. There was no free oxygen in earth's atmosphere until about 2000 million years ago, but there were photosynthesizing cyanobacteria. The head frame of the Tau Tona Mine is the lone entrance to over 500 miles of tunnels. Building Publications, Pretoria. The continued mining of gold has firmly placed Johannesburg as the economical powerhouse of South Africa. Committed to academic and research excellence, Wits generates high level scarce skills for a globally competitive world, while addressing local social and economic development. The gold fields of the Witwatersrand Basin in South Africa are, by a landslide, the largest single gold producing district in the world. It is the source of over 40% of the gold extracted from the Earth. The outcrop in Gauteng forms the Witwatersrand ridge, from which the basin and its rocks derive their name. Evidence from tungsten isotope studies indicates that most gold in the crust is derived from gold in the mantle which resulted from a meteorite bombardment some 3900 million years ago (i.e. pp. [6] In fact, apart from the Witwatersrand outcrops (i.e. Although many of the older mines, around Johannesburg, are now nearly exhausted, the Witwatersrand Basin still produces most of South Africa's gold and much of the total world output. Gold rushes throughout the world have created massive cultural shifts that resonate to this day. Gold was discovered in the area known as Witwatersrand, triggering what would become the Witwatersrand Gold Rush of 1886. [7] Thus, it is possible that if it had not been for the Vredefort meteor strike 2000 million years ago, we would either have never discovered the rich gold deposits beneath the Southern African surface, or they would have been eroded away during the uninterrupted removal of a several kilometres thick layer of deposits from the surface of the Southern African Plateau in the relatively recent geological past: i.e. All of our sapphires are cut on our premises and are available loose or mounted in a custom setting. The 200-by-350-km (124-by-217-mile) Witwatersrand Basin contains an 11-km- (7-mile-) thick sequence of lavas and sediments that are 3 billion years old. He is a recipient of many awards including the American Society of Haematology Global Capacity Building award (2019), the Publons Top 1% Cross-Field Reviewer Award (2019), the Wits Vice-chancellor Academic Citizenship Award (2018) and the Novo Nordisk Haemophilia Foundation International Haemophilia Community Award (2018). It might be related to the collision of the Kaapvaal Craton with the Zimbabwe Craton, eventually to become knitted together to form a single continental unit. #Witsie4Life Storytelling Series Wits Alumni Relations presents the #Witsie4Life storytelling series, shining a light on ordinary people doing extraordinary things. The result was alternating red and gray layers of mud which, when consolidated, became banded ironstones. While the ultimate source of the gold in the Witwatersrand reef is unknown, the general disposition of the deposits is recognizable and continuous. There were no continents during the early stages of the Archean Eon,[11] but island arcs did form. The result was a 2500 m thick layer of rock that is termed the “Central Rand Group”, which together with the “West Rand Group”, forms the “Witwatersrand Supergroup”. 10:30am - 6pm ET, Showroom & Workshop 297–301. In addition to the founding of Johannesburg, the Witwatersrand Gold Rush was a major factor leading to the, The Boer farmers denied these “uitlanders” voting rights and mounted heavy taxes on the gold industry. The entire series of rocks, known as the "Witwatersrand Supergroup," consists of very hard erosion resistant quartzites, banded ironstones and some marine lava deposits, interspersed with softer, more easily eroded tillites, mudstones and conglomerates. The Witwatersrand Supergroup strata which reach the surface in Johannesburg dip downwards to the south at an angle of about 30°. Cyanobacteria grew in relative abundance in these mineral rich waters. W.H. This protected it from erosion later on; but, possibly more importantly, bringing it to the surface close to the crater rim, near Johannesburg. [2][6] The impact was close to the present village of Vredefort, which has given its name to the geological remnant of this immense event: the Vredefort Dome. ... in what is now known … The University Wits is a phrase used to name a group of late 16th-century English playwrights and pamphleteers who were educated at the universities (Oxford or … It is a range of hills in the Gauteng province South Africa that contains most of the worlds gold reserves. The huge deposits of gold in this region were the prime factor responsible for the growth and development of the city of Johannesburg, and also greatly aided the economy of South Africa as a whole for decades. Witwatersrand and the Rand are names for the conurbation that developed along the range, although the terms are falling into disuse[citation needed] and Witwatersrand was the "W" in PWV (Pretoria-Witwatersrand-Vereeniging), the initial name of Gauteng province. Some of these gold bearing fan deltas are now at depths of 4 km below the surface. The Witwatersrand plateau forms a continental divide, with the run-off to the north draining into the Indian Ocean via the Crocodile and Limpopo rivers, while the run-off to the south drains via the Vaal into the Orange River and ultimately into the Atlantic Ocean.[2][4][5]. at approximately the time that the Kaapvaal Craton formed). A final event that had a major impact on the geology of the Witwatersrand Basin and its exposure in the Johannesburg region, was a massive meteor impact 110 km to the south-west of Johannesburg 2020 million years ago. [17] The park is on the busy Main Reef Road, immediately west of Nasrec Road. It took very little time for the local village of Ferreira’s Camp to transform into the Ferreira Township as miners settled in the region hoping to strike gold. Iron pyrite (FeS2), which is relatively plentiful in the gold ores of the Witwatersrand, oxidises to insoluble ferric oxide (Fe2O3) and sulfuric acid (H2SO4). pp. [6] The floor of this newly formed “Witwatersrand sea” consisted of smoothly eroded granites. The Witwatersrand plateau consists of a 5000-to-7000-metre-thick (3.1–4.3 mi) layer of mainly sedimentary rocks laid down over a period of about 260 million years, starting approximately 2.97 billion years ago. As gold fever crested, the steady influx of foreigners was unsettling to Boer farmers who were already established in the region. [6][15][16] Sulfuric acid also erodes concrete and cement structures, resulting in structural damage to buildings and bridges.[15][16]. The rocks of the "Rand" or reef, as the Witwatersrand is sometimes known, are rich in uranium and gold. Today, the Witwatersrand reef is part of the “golden arc,” an ancient inland lake containing rich deposits of alluvial gold. [6][12] Within 60 million years, up to 4500 m of sediment had accumulated on the granite base, to become the “West Rand Group” of rocks that contribute over 60% of the total thickness of the Witwatersrand Supergroup. Mon - Fri: 10:30am - 6:00pm ET It has since been established that the rocks that make up the Witwatersrand Ridge dip downwards and southwards to form the largely underground “Witwatersrand Basin” which covers an elliptical area with a 300 km long major axis from Evander in the north-east to Theunissen in the south-west, and 150 km wide stretching from Steynsrus in the south-east to Coligny in the north-west,[1] with a small subsidiary basin at Kinross. The extreme economic significance of this g… The meteor impact, however, lowered the Witwatersrand basin inside the crater. Commonly known as Wits University or just Wits, the University Of Witwatersrand is a multi-campus public research university in South Africa that is … The Mesoarchaean Witwatersrand Basin represents the largest known gold anomaly and has produced more gold than any other ore province in the world. Harrison declared his claim with the then-government of the Zuid Afrikaanse Republiek (ZAR), and in September 1886 President Paul Kruger issued a proclamation declaring nine farms public mining diggings, starting on 20 September 1886. Why Do Labs Not Agree On Sapphire Gradings? The area of the craton on top of which Johannesburg is now situated, became a vast riverine plain, which extended along the entire northern and western shoreline of the shrunken sea, in an arc extending from Evander in the east, through Johannesburg, Carletonville and then southwards to Klerksdorp and Welkom in the south-west. What Does ‘Natural’ and ‘Untreated’ Mean? Our sapphires are not synthetic, heated to extreme temperatures, diffused, irradiated, glass filled or oiled. It was laid down in two stages, over the course of 260 million years starting just short of 3000 million years ago. Within ten years, the town became the largest in South Africa, growing to be larger than Cape Town, which had been the largest city for over 200 years. It holds the world's largest known gold reserves and has produced over 1.5 billion ounces (over 40,000 metric tons), which represents about 22% of all the gold accounted for above the surface.
