Nooitgedacht Glacial Pavements
The Nooitgedacht Glacial Pavements comprise a geological feature between Kimberley and Barkly West, South Africa, pertaining to the Palaeozoic-age Dwyka Ice Age, or Karoo Ice Age, (some 300 million years ago) where the glacially scoured (smoothed and striated) ancient bedrock (re-exposed by erosion) was used, substantially more recently, during the Later Stone Age period in the late Holocene as panels for rock engravings. Ice Age Some 300-290 million years ago, during Dwyka times, what is now Southern Africa was, as a result of plate tectonics, near the South Pole and large ice sheets or glaciers covered high-lying areas. Geologists term this upland the Cargonian Highlands, stretching from what is now the Northern Cape through Gauteng to Mpumalanga. As the Dwyka glaciers moved, grinding their way southwards, the rocks and rubble that became embedded in their belly smoothed the underlying Andesite rock pavements and scoured out scratch marks, known as striations. As the ice sha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Andesite
Andesite () is a volcanic rock of intermediate composition. In a general sense, it is the intermediate type between silica-poor basalt and silica-rich rhyolite. It is fine-grained (aphanitic) to porphyritic in texture, and is composed predominantly of sodium-rich plagioclase plus pyroxene or hornblende. Andesite is the extrusive equivalent of plutonic diorite. Characteristic of subduction zones, andesite represents the dominant rock type in island arcs. The average composition of the continental crust is andesitic. Along with basalts, andesites are a component of the Martian crust. The name ''andesite'' is derived from the Andes mountain range, where this rock type is found in abundance. It was first applied by Christian Leopold von Buch in 1826. Description Andesite is an aphanitic (fine-grained) igneous rock that is intermediate in its content of silica and low in alkali metals. It has less than 20% quartz and 10% feldspathoid by volume, with at least 65% of the fe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nicolaas Waterboer
Nic(h)olaas Waterboer (1819 - 17 September 1896) was a leader ("Kaptijn") of the Griqua people. He was the last fully independent Griqua Kaptijn of Griqualand West, and after it became a British colony, his rule and that of his successors was largely nominal. Early life He was the eldest son of Andries Waterboer who had founded the Waterboer dynasty, and his wife Gertruida Pienaar. After his father's death in 1852, Nicolaas was proclaimed the ''Kaptijn'' (Captain) of Griqualand West at the Kaptijn's Residence in Griekwastad ("Griquatown"). Rule (1852-1896) He ruled during the tumultuous era that followed the discovery of diamonds on his land in the 1860s. As enormous numbers of "diggers" arrived and the population of the diamond fields exploded, tensions grew between the different groups - including the Griquas, the indigenous Tswana people, the Boers and the white English diggers. Disagreements ensued on exactly what the borders of the semi-nomadic Griquas' land was, and a ra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Griqua People
The Griquas (; af, Griekwa, often confused with ''!Orana'', which is written as ''Korana'' or ''Koranna'') are a subgroup of heterogeneous former Khoe-speaking nations in Southern Africa with a unique origin in the early history of the Cape Colony. Text was copied from this source, which is available under a Creative Commons license. Under apartheid, they were given a special racial classification under the broader category of "Coloured". Similar to the Trekboers (another Afrikaans-speaking group of the time), they originally populated the frontiers of the nascent Cape Colony (founded in 1652). The men of their semi-nomadic society formed commando units of mounted gunmen. Like the Boers, they migrated inland from the Cape, in the 19th century establishing several states in what are now South Africa and Namibia. Griqua was the name given to a mixed-race culture in the Cape Colony of South Africa, around the 17th and 18th Century (Taylor, 2020). They were also known as Hotten ...

South African Republic
The South African Republic ( nl, Zuid-Afrikaansche Republiek, abbreviated ZAR; af, Suid-Afrikaanse Republiek), also known as the Transvaal Republic, was an independent Boer Republic in Southern Africa which existed from 1852 to 1902, when it was annexed into the British Empire as a result of the Second Boer War. The ZAR was established as a result of the 1852 Sand River Convention, in which the Government of the United Kingdom, British government agreed to formally recognise independence of the Boers living north of the Vaal River. Relations between the ZAR and Britain started to deteriorate after the British Cape Colony expanded into the Southern African interior, eventually leading to the outbreak of the First Boer War between the two nations. The Boer victory confirmed the ZAR's independence; however, Anglo-ZAR tensions soon flared up again over various diplomatic issues. In 1899, war again broke out between Britain and the ZAR, which was swiftly occupied by the British mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free State (South African Province)
The Free State, known as Orange Free State until the 28th of June 1995 when its name was changed, is a province of South Africa. Its capital is Bloemfontein, which is also South Africa's judicial capital. Its historical origins lie in the Boer republic called the Orange Free State and later Orange Free State Province. History The current borders of the province date from 1994 when the Bantustans were abolished and reincorporated into South Africa. It is also the only one of the four original provinces of South Africa not to undergo border changes, apart from the reincorporation of Bantustans, and its borders date from before the outbreak of the Boer War. Law and government The provincial government consists of a premier, an executive council of ten ministers, and a legislature. The provincial assembly and premier are elected for five-year terms, or until the next national election. Political parties are awarded assembly seats based on the percentage of votes each party receive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Driekops Eiland
Driekops Eiland (also called Driekopseiland) is a rock engraving or petroglyph site in the bed of the Riet River close to the town of Plooysburg, near Kimberley, Northern Cape, South Africa. The engravings There are more than 3500 individual engravings at this site, predominantly pecked geometric images, occur on glaciated basement rock exposed in the bed of the river and are submerged when the river rises. Archaeologists and geomorphologists have estimated that the engravings may have been made in two episodes – before about 2500 years ago and after about 1000 years ago. Debates The site has been at the centre of a number of debates about South African rock engravings. Sensational claims about the site and makers of the engravings are advanced by Brenda Sullivan, Cyril Hromnik and others in books such as ''Spirit of the rocks''. The ideas set out by these authors, often involving ancient visitors from foreign lands, and alleged links between the engravings and Ogham inscriptio ...

Petroglyph
A petroglyph is an image created by removing part of a rock surface by incising, picking, carving, or abrading, as a form of rock art. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs are found worldwide, and are often associated with prehistoric peoples. The word comes from the Greek prefix , from meaning "stone", and meaning "carve", and was originally coined in French as . Another form of petroglyph, normally found in literate cultures, a rock relief or rock-cut relief is a relief sculpture carved on "living rock" such as a cliff, rather than a detached piece of stone. While these relief carvings are a category of rock art, sometimes found in conjunction with rock-cut architecture, they tend to be omitted in most works on rock art, which concentrate on engravings and paintings by prehistoric or nonliterate cultures. Some of these reliefs exploit the rock's nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vaal River
The Vaal River ( ; Khoemana: ) is the largest tributary of the Orange River in South Africa. The river has its source near Breyten in Mpumalanga province, east of Johannesburg and about north of Ermelo and only about from the Indian Ocean. It then flows westwards to its conjunction with the Orange River southwest of Kimberley in the Northern Cape. It is long, and forms the border between Mpumalanga, Gauteng and North West Province on its north bank, and the Free State on its south. It is the third largest river in South Africa after the Orange River (2200 km long) and the Limpopo River (1750 km long) and was established as the main source of water for the great Witswatersrand area after the gold rush during the 19th century. The Vaal Dam lies on the Vaal River in Deneysville just south of the border between Gauteng and the Free State. It is also important to note that the Vaal River is the longest river wholly within the borders of South Africa. ''Vaal'' is a D ...

Karoo Sequence
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.
