Wildebeest Kuil Rock Art Centre
Wildebeest Kuil Rock Art Centre is a rock engraving site with visitor centre on land owned by the !Xun and Khwe San situated about 16 km from Kimberley, Northern Cape, South Africa. It is a declared Provincial Heritage Site managed by the Northern Cape Rock Art Trust in association with the McGregor Museum. The engravings exemplify one of the forms often referred to as ‘ Bushman rock art' – or Khoe-San rock art – with the rock paintings of the Drakensberg, Cederberg and other regions of South Africa being generally better known occurrences. Differing in technique, the engravings have many features in common with rock paintings. A greater emphasis on large mammals such as elephant, rhino and hippo, in addition to eland, and an often reduced concern with depicting the human form set the engravings apart from the paintings of the sub-continent.

Petroglyphs
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 na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
George William Stow
George William Stow (2 February 1822, Nuneaton, Warwickshire, England – 17 March 1882, Heilbron, Orange Free State) was a South African geologist and ethnologist, a poet, historian, artist, cartographer, and writer. Biography Stow received his education at a school on the Isle of Dogs. He was articled to a Dr. Lattey of London and was intended to follow a medical career. At age 21, having little desire to become a member of the medical profession, he emigrated to South Africa, landing at Port Elizabeth in December 1843. In turn he taught at a mission near Cuylerville, was a clerk in the commissariat, tried his hand at farming, became a book-keeper in Port Elizabeth, a trader in Queenstown and a wine-merchant, diamond dealer and auctioneer in Kimberley. Seeking refuge in the Renosterberg range near Middelburg during the Eighth Frontier War, he found an Early Triassic fossil skull resembling an amphibian. Thereafter Stow spent a great deal of his time exploring the Cretac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cation Ratio Dating
An ion () is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of electrons is unequal to its total number of protons. A cation is a positively charged ion with fewer electrons than protons while an anion is a negatively charged ion with more electrons than protons. Opposite electric charges are pulled towards one another by electrostatic force, so cations and anions attract each other and readily form ionic compounds. Ions consisting of only a single atom are termed atomic or monatomic ions, while two or more atoms form molecular ions or polyatomic ions. In the case of physical ionization in a fluid (gas or liquid), "ion pairs" are created by spontaneous molecule collisions, where each generated pair consists of a free electron and ...

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 ...

Karoo
The Karoo ( ; from the Afrikaans borrowing of the South Khoekhoe !Orakobab or Khoemana word ''ǃ’Aukarob'' "Hardveld") is a semi-desert natural region of South Africa. No exact definition of what constitutes the Karoo is available, so its extent is also not precisely defined. The Karoo is partly defined by its topography, geology and climate, and above all, its low rainfall, arid air, cloudless skies, and extremes of heat and cold.Potgieter, D.J. & du Plessis, T.C. (1972) ''Standard Encyclopaedia of Southern Africa''. Vol. 6. pp. 306–307. Nasou, Cape Town.''Reader’s Digest Illustrated Guide to Southern Africa''. (5th Ed. 1993). pp. 78–89. Reader’s Digest Association of South Africa Pty. Ltd., Cape Town. The Karoo also hosted a well-preserved ecosystem hundreds of million years ago which is now represented by many fossils. The ǃ’Aukarob formed an almost impenetrable barrier to the interior from Cape Town, and the early adventurers, explorers, hunters, and travelers o ...

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] |
Northern Cape
The Northern Cape is the largest and most sparsely populated province of South Africa. It was created in 1994 when the Cape Province was split up. Its capital is Kimberley. It includes the Kalahari Gemsbok National Park, part of the Kgalagadi Transfrontier Park and an international park shared with Botswana. It also includes the Augrabies Falls and the diamond mining regions in Kimberley and Alexander Bay. The Namaqualand region in the west is famous for its Namaqualand daisies. The southern towns of De Aar and Colesberg found within the Great Karoo are major transport nodes between Johannesburg, Cape Town and Port Elizabeth. Kuruman can be found in the north-east and is known as a mission station. It is also well known for its artesian spring and Eye of Kuruman. The Orange River flows through the province of Northern Cape, forming the borders with the Free State in the southeast and with Namibia to the northwest. The river is also used to irrigate the many vineyards in the ... [...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 ...

London
London is the capital and largest city of England and the United Kingdom, with a population of just under 9 million. It stands on the River Thames in south-east England at the head of a estuary down to the North Sea, and has been a major settlement for two millennia. The City of London, its ancient core and financial centre, was founded by the Romans as '' Londinium'' and retains its medieval boundaries.See also: Independent city § National capitals The City of Westminster, to the west of the City of London, has for centuries hosted the national government and parliament. Since the 19th century, the name "London" has also referred to the metropolis around this core, historically split between the counties of Middlesex, Essex, Surrey, Kent, and Hertfordshire, which largely comprises Greater London, governed by the Greater London Authority.The Greater London Authority consists of the Mayor of London and the London Assembly.

Colonial And Indian Exhibition
The Colonial and Indian Exhibition of 1886 was held in South Kensington in London with the objective to (in the words of the then Prince of Wales) "stimulate commerce and strengthen the bonds of union now existing in every portion of her Majesty's Empire". The exhibition was opened by Queen Victoria, and when it closed had received 5.5 million visitors. It was housed in a collection of purpose-built buildings designed in an Indian style. Display In 1886, the bonds of the Empire were intended to be strengthened by the Colonial and Indian Exhibition. In New Zealand, there was a suggestion that the showcases should be made of native woods. A fernery was included in the New Zealand Court and a display of frozen mutton represented the burgeoning agricultural industries. A pātaka (storehouse), originally carved in the 1850s dominated the large Maori collection assembled by naturalist Walter Buller along with the tomb of a Ngati Pikiao chief.
