Winterberg, Eastern Cape
The Great Winterberg is an extensive east–west mountain range lying immediately north of the small towns of Bedford, Adelaide and Fort Beaufort in the Eastern Cape of South Africa. Elevation on average is about 1800 metres above sea-level. The Great Winterberg Peak north of Adelaide rises to 2371 metres, high enough to be occasionally covered in snow. The underlying geology consists of shales and sandstones of the Beaufort Series of the Karoo System, frequently with dolerite intrusions. Rainfall on the southern slopes (facing the sea) is fairly high. A notable pass over the range is the Katberg Pass Katberg Pass is a mountain pass situated in the Eastern Cape province of South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa.

Bedford, Eastern Cape
Bedford or Nyarha is a rural town in the centre of the Eastern Cape province of South Africa. It was established in the mid-19th century when Sir Andries Stockenstroom sold portions of land from his farm Maastroom to raise funds for the restoration of his library, which had been burnt by British soldiers mistrustful of his attempts to broker peace in one of the Cape Frontier Wars. The farm is still there and open for visitors. It is located on the southern edge of the Winterberg mountain range, in the ''Smaldeel'' (a narrow strip of grassland running laterally from Fort Beaufort to Somerset East, renowned for its sweet grass). The town suffered a major decline in fortunes in the latter half of the 20th century before reviving itself around the turn of the millennium. It is regarded today as an artist's haven and retirement village. The lack of industry in the town, while a boon to those hoping to escape the rat race, means that the town has a large unemployment rate. The woes o ...

Adelaide, Eastern Cape
Adelaide is a rural town and farming area in the Eastern Cape Province of South Africa. Adelaide is situated at the foothills of the Great Winterberg mountain range, 22 km east of Bedford and 37 km west of Fort Beaufort. History Before European arrival The modern day area of Adelaide was first inhabited by Bushmen and Xhosa people (estimated around 1530 to 1760), but in the late 18th and 19th century white farmer settlers arrived here. Some Bushmen were displaced while some intermarried with Xhosa people such as the Gqunukhwebe, Gqwashu and Sukwini people. Colonial Adelaide Adelaide's origins date back to 1835 when a British officer named Captain Alexander Boswell Armstrong (1787–1862) established a military encampment which he named ''Fort Adelaide'' after Adelaide of Saxe-Meiningen, wife of King William IV. Despite the earlier English settlers, who were part of the 1820 Settlers, later on a large number of both Scottish and Afrikaans people soon immigrated h ...

Fort Beaufort
Fort Beaufort (Xhosa: iBhofolo) is a town in the Amatole District of South Africa's Eastern Cape Province, and had a population of 25,668 in 2011. The town was established in 1837 and became a municipality in 1883. The town lies at the confluence of the Kat River and Brak River between the Keiskamma and Great Fish Rivers. Fort Beaufort serves as a mini-'dormitory' for academic staff and students of Fort Hare University, based in the nearby town of Alice, and is also close to Sulphur Springs. It is also the birthplace of South African politician and anti-apartheid activist who is also the first Premier of the Eastern Cape Raymond Mhlaba and his former first wife Joyce Meke. History The roots of Fort Beaufort is a mission station that the Reverend Joseph Williams of the London Missionary Society established in 1816. In 1822, Colonel Maurice Scott of the Royal Warwickshire Regiment constructed a blockhouse about three miles from the mission station as a military frontier post and ...

Eastern Cape
The Eastern Cape is one of the provinces of South Africa. Its capital is Bhisho, but its two largest cities are East London and Gqeberha. The second largest province in the country (at 168,966 km2) after Northern Cape, it was formed in 1994 out of the Xhosa homelands or bantustans of Transkei and Ciskei, together with the eastern portion of the Cape Province. The central and eastern part of the province is the traditional home of the indigenous Xhosa people. In 1820 this area which was known as the Xhosa Kingdom began to be settled by Europeans who originally came from England and some from Scotland and Ireland. Since South Africa's early years, many Xhosas believed in Africanism and figures such as Walter Rubusana believed that the rights of Xhosa people and Africans in general, could not be protected unless Africans mobilized and worked together. As a result, the Eastern Cape is home to many anti-apartheid leaders such as Robert Sobukwe, Oliver Tambo, Nelson Mandel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Africa
South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countries of Namibia, Botswana, and Zimbabwe; and to the east and northeast by Mozambique and Eswatini. It also completely enclaves the country Lesotho. It is the southernmost country on the mainland of the Old World, and the second-most populous country located entirely south of the equator, after Tanzania. South Africa is a biodiversity hotspot, with unique biomes, plant and animal life. With over 60 million people, the country is the world's 24th-most populous nation and covers an area of . South Africa has three capital cities, with the executive, judicial and legislative branches of government based in Pretoria, Bloemfontein, and Cape Town respectively. The largest city is Johannesburg. About 80% of the population are Black South Afri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers ( laminae) less than one centimeter in thickness. This property is called '' fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the more narrow sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks into thin layers, often splintery and usually parallel to the otherwise indistinguishable beddin ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually related to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaufort Series
The Beaufort Group is the third of the main subdivisions of the Karoo Supergroup in South Africa. It is composed of a lower Adelaide Subgroup and an upper Tarkastad Subgroup. It follows conformably after the Ecca Group and unconformably underlies the Stormberg Group. Based on stratigraphic position, lithostratigraphic and biostratigraphic correlations, palynological analyses, and other means of geological dating, the Beaufort Group rocks are considered to range between Middle Permian (Wordian) to Early Triassic (Anisian) in age. Background During the period when sedimentation of the Beaufort Group rocks took place, the Ecca sea had retreated to the northeastern Karoo Basin. All sediment deposition at this time took place in a terrestrial, although in a predominantly fluvial or alluvial environment that was seasonally arid. This environment covered a vast area and deposition was influenced by a retroarc foreland basin. This foreland system was caused by crustal uplift (orog ...

Karoo System
The Karoo Supergroup is the most widespread stratigraphic unit in Africa south of the Kalahari Desert. The supergroup consists of a sequence of units, mostly of nonmarine origin, deposited between the Late Carboniferous and Early Jurassic, a period of about 120 million years. In southern Africa, rocks of the Karoo Supergroup cover almost two thirds of the present land surface, including all of Lesotho, almost the whole of Free State, and large parts of the Eastern Cape, Northern Cape, Mpumalanga and KwaZulu-Natal Provinces of South Africa. Karoo supergroup outcrops are also found in Namibia, Eswatini, Zambia, Zimbabwe and Malawi, as well as on other continents that were part of Gondwana. The basins in which it was deposited formed during the formation and breakup of Pangea.McCarthy, T., Rubridge, B. (2005). ''The Story of Earth and Life.'' pp. 161, 187–241.

Dolerite
Diabase (), also called dolerite () or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). ''Diabase'' is the preferred name in North America, while ''dolerite'' is the preferred name in the rest of the English-speaking world, where sometimes the name ''diabase'' refers to altered dolerites and basalts. Some geologists prefer to avoid confusion by using the name ''microgabbro''. The name ''diabase'' comes from the French ', and ultimately from the Greek - meaning "act of crossing over, transition". Petrography Diabase normally has a fine but visible texture of euhedral lath-shaped plagioclase crystals (62%) set in a finer matrix of clinopyroxene, typically augite (20–29%), with minor olivine (3% up to 12% in olivine diabase), magnetite (2%), and ...

Katberg Pass
Katberg Pass is a mountain pass situated in the Eastern Cape province of South Africa South Africa, officially the Republic of South Africa (RSA), is the southernmost country in Africa. It is bounded to the south by of coastline that stretch along the South Atlantic and Indian Oceans; to the north by the neighbouring countri ..., on the R351 between Seymour and Whittlesea. The pass climbs almost 700 meters in altitude to summit at 1622m ASL. The average gradient is 1:15 with some sections as steep as 1:3. Construction commenced in 1854 and was built by Andrew Geddes Bain. He was unable to complete it so it was ultimately completed by Adam de Smidt.

Andrew Geddes Bain
Andrew Geddes Bain (baptised 11 June 1797 – 20 October 1864), was a South African geologist, road engineer, palaeontologist and explorer. Life history The only child of Alexander Bain and Jean Geddes, both of whom died when Bain was still a young boy, Bain was baptised 11 June 1797 in Thurso, Scotland. He was raised by an aunt who lived near Edinburgh. Here he received a classical education, but no vocational training. In 1816 he emigrated to Cape Town accompanied by his uncle Lieutenant Colonel William Geddes of the 83rd Regiment, who was stationed in the Cape. He married Maria Elizabeth von Backstrom on 16 November 1818 and had 3 sons and 7 daughters. In 1822 he bought property in Graaff Reinet and carried on for some years the business of a saddler. In 1825 he accompanied John Burner Biddulph on a trading expedition to Kuruman, the mission outpost on the edge of the Kalahari and home of Dr. Robert Moffat (father-in-law of David Livingstone). They explored further north an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
