Abrahamskraal Formation
The Abrahamskraal Formation is a geological formation and is found in numerous localities in the Northern Cape, Western Cape, and the Eastern Cape of South Africa. It is the lowermost formation of the Adelaide Subgroup of the Beaufort Group, a major geological group that forms part of the greater Karoo Supergroup. It represents the first fully terrestrial geological deposits of the Karoo Basin. Outcrops of the Abrahamskraal Formation are found from the small town Middelpos in its westernmost localities, then around Sutherland, the Moordenaarskaroo north of Laingsburg, Williston, Fraserburg, Leeu-Gamka, Loxton, and Victoria West in the Western Cape and Northern Cape. In the Eastern Cape outcrops are known from Rietbron, north of Klipplaat and Grahamstown, and also southwest of East London. Geology The Abrahamskraal Formation comprises the majority of the Middle Permian Beaufort sequence, and are thought to range between 268 - 259 million years in age. The lowermost deposits o ...

Geological Formation
A geological formation, or simply formation, is a body of rock having a consistent set of physical characteristics ( lithology) that distinguishes it from adjacent bodies of rock, and which occupies a particular position in the layers of rock exposed in a geographical region (the stratigraphic column). It is the fundamental unit of lithostratigraphy, the study of strata or rock layers. A formation must be large enough that it can be mapped at the surface or traced in the subsurface. Formations are otherwise not defined by the thickness of their rock strata, which can vary widely. They are usually, but not universally, tabular in form. They may consist of a single lithology (rock type), or of alternating beds of two or more lithologies, or even a heterogeneous mixture of lithologies, so long as this distinguishes them from adjacent bodies of rock. The concept of a geologic formation goes back to the beginnings of modern scientific geology. The term was used by Abraham Gottlob Wer ...

Karoo Supergroup
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.

Permian
The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Paleozoic Era; the following Triassic Period belongs to the Mesozoic Era. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the region of Perm in Russia. The Permian witnessed the diversification of the two groups of amniotes, the synapsids and the sauropsids ( reptiles). The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, which could better cope with these drier conditions, rose to dominance in place of their am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Leeu-Gamka
Leeu-Gamka is a small town in the Western Cape province of South Africa, located north-east of Cape Town in the Karoo. History The town of Leeu-Gamka owes its existence to the route chosen by Prime Minister John Molteno for the Cape Government Railways's western main line, from Cape Town towards the diamond fields at Kimberley. The railway line reached the meeting-point of the Leeu and Gamka rivers in 1879, and on 11 August of that year a station was opened on that location. It was initially named "Fraserburg Road", because it was the closest station to the town of Fraserburg, to the north-west over the Nuweveld Mountains. A small town grew around this station, with a church and school opening in 1896, and a hotel in 1898. In 1950 the station and town were renamed to "Leeu-Gamka". Geography Leeu-Gamka is located where the Leeu River enters the Gamka River; both rivers are intermittent in this region. "Leeu" and "Gamka" both mean "Lion", in Afrikaans and ǀXam respectively.

Williston, Northern Cape
Williston is a town in Northern Cape, South Africa. Town 103 km north-east of Calvinia and 140 km south-west of Carnarvon. History Williston was originally known as Amandelboom (''Afrikaans'' "almond tree") as a large almond tree stood as the focal point of the town by the Sak River. The tree had been planted in 1768 by Johan Abraham Nel, a farmer and owner of the land that was to become the town, to commemorate the birth of one of his sons. In the early 19th century, the district was populated by pastoralists who constantly moved their livestock between springs in search of fresh grazing areas. These pastoralists were derogatorily referred to as 'Basters' as the pastoralists were of mixed race and descendants of the Khoi and Dutch. In 1845, the community requested that the Rhenish Church, which had a mission station in Wuppertal, establish another mission station in Williston. Two missionaries were sent to Williston to assist the community with their spiritual needs. By ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
