Bogenfels
Bogenfels is a location in the coastal Namib Desert of Namibia, noted for its natural rock formations (hence the name, which means "arch rock" in German). The main formation is a high rock arch close to the coast. It is not easily accessible, due to the terrain and its location within a restricted diamond-mining area Sperrgebiet, at 27° 28'S, about south of Lüderitz and south of Pomona but there are official guided tours. Geology With its highest point at above sea level, the formation is a mix of hard dolomite and soft shale. Town A settlement developed in the area after diamonds were discovered. In 1950, it was evacuated and has remained a ghost town since. A narrow-gauge railway line once ran to Kolmanskop Kolmanskop (Afrikaans for “Coleman's head”, german: Kolmannskuppe) is a ghost town in the Namib in southern Namibia, ten kilometres inland from the port town of Lüderitz. It was named after a transport driver named Johnny Coleman who, during .... Phila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Namib Desert
The Namib ( ; pt, Namibe) is a coastal desert in Southern Africa. The name is of Khoekhoegowab origin and means "vast place". According to the broadest definition, the Namib stretches for more than along the Atlantic coasts of Angola, Namibia, and South Africa, extending southward from the Carunjamba River in Angola, through Namibia and to the Olifants River (Western Cape), Olifants River in Western Cape, South Africa. The Namib's northernmost portion, which extends from the Angola-Namibia border, is known as Moçâmedes Desert, while its southern portion approaches the neighboring Kalahari Desert. From the Atlantic coast eastward, the Namib gradually ascends in elevation, reaching up to inland to the foot of the Great Escarpment, Southern Africa, Great Escarpment. Annual precipitation ranges from in the most arid regions to at the escarpment, making the Namib the only true desert in southern Africa. Having endured Desert climate, arid or Semi-arid climate, semi-arid cond ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rock Formation
A rock formation is an isolated, scenic, or spectacular surface rock outcrop. Rock formations are usually the result of weathering and erosion sculpting the existing rock. The term ''rock formation'' can also refer to specific sedimentary strata or other rock unit in stratigraphic and petrologic studies. A rock structure can be created in any rock type or combination: * Igneous rocks are created when molten rock cools and solidifies, with or without crystallisation. They may be either plutonic bodies or volcanic extrusive. Again, erosive forces sculpt their current forms. * Metamorphic rocks are created by rocks that have been transformed into another kind of rock, usually by some combination of heat, pressure, and chemical alteration. * Sedimentary rocks are created by a variety of processes but usually involving deposition, grain by grain, layer by layer, in water or, in the case of terrestrial sediments, on land through the action of wind or sometimes moving ice.

Namibia
Namibia (, ), officially the Republic of Namibia, is a country in Southern Africa. Its western border is the Atlantic Ocean. It shares land borders with Zambia and Angola to the north, Botswana to the east and South Africa to the south and east. Although Kazungula, it does not border Zimbabwe, less than 200 metres (660 feet) of the Botswanan right bank of the Zambezi, Zambezi River separates the two countries. Namibia gained independence from South Africa on 21 March 1990, following the Namibian War of Independence. Its capital and largest city is Windhoek. Namibia is a member state of the United Nations (UN), the Southern African Development Community (SADC), the African Union (AU) and the Commonwealth of Nations. The driest country in sub-Saharan Africa, Namibia has been inhabited since pre-historic times by the San people, San, Damara people, Damara and Nama people. Around the 14th century, immigration, immigrating Bantu peoples arrived as part of the Bantu expansion. Since ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arch
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent collapse ...

Lüderitz
Lüderitz is a town in the ǁKaras Region of southern Namibia. It lies on one of the least hospitable coasts in Africa. It is a port developed around Robert Harbour and Shark Island. The town is known for its colonial architecture, including some Art Nouveau work, and for wildlife including seals, penguins, flamingos and ostriches. It is also home to a museum, and lies at the end of a decommissioned railway line to Keetmanshoop. The town is named after Adolf Lüderitz, founder of the German South West Africa colony. Economy and infrastructure The centre of Lüderitz' economic activity is the port, until the incorporation of the exclave Walvis Bay in 1994 the only suitable harbour on Namibia's coast. However, the harbour at Lüderitz has a comparatively shallow rock bottom, making it unusable for many modern ships. The recent addition of a new quay has allowed larger fishing vessels to dock at Lüderitz. The town has also re-styled itself in an attempt to lure tourists t ...

Dolomite (rock)
Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO3)2. It occurs widely, often in association with limestone and evaporites, though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 million years in age). The first geologist to distinguish dolomite rock from limestone was Belsazar Hacquet in 1778. Most dolomite was formed as a magnesium replacement of limestone or of lime mud before lithification. The geological process of conversion of calcite to dolomite is known as dolomitization and any intermediate product is known as dolomitic limestone. The "dolomite problem" refers to the vast worldwide depositions of dolomite in the past geologic record in contrast to the limited amounts of dolomite formed in modern times. Recent research has revealed sulfate-reducing bacteria living in anoxic conditions precipitate dolomite which ind ... [...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 ...

Kolmanskop
Kolmanskop (Afrikaans for “Coleman's head”, german: Kolmannskuppe) is a ghost town in the Namib in southern Namibia, ten kilometres inland from the port town of Lüderitz. It was named after a transport driver named Johnny Coleman who, during a sand storm, abandoned his ox wagon on a small incline opposite the settlement. Once a small but very rich mining village, it is now a tourist destination run by the joint firm Namibia- De Beers. History Foundation and peak In 1908, in what was then German South-West Africa, the worker Zacharias Lewala found a diamond while working in this area and showed it to his supervisor, the German railway inspector August Stauch. Realizing the area was rich in diamonds, German miners began settlement, and soon after the German Empire declared a large area as a "'' Sperrgebiet''", starting to exploit the diamond field. Driven by the enormous wealth of the first diamond miners, the residents built the village in the architectural style of a German ...
