Amaro Mountains
The Amaro Mountains are a mountain range in south western Ethiopia. Extending 60 kilometers along a north–south axis east of Lake Chamo, these mountains are located in the Nechisar National Park, which lies in the Amaro special woreda. These elevations expose an assemblage of uniform, fine-grained, holocrystalline olivine-basalts with local tuff bands, resting upon the basement complex. It is uncertain whether these mountains are a remnant plateau now looking down on the grabens to either side (the Gelana and Ganjule grabens), or if these mountains were squeezed up from the basement of the East African Rift, possibly by processes similar to those that formed the Ruwenzori Mountains The Ruwenzori, also spelled Rwenzori and Rwenjura, are a range of mountains in eastern equatorial Africa, located on the border between Uganda and the Democratic Republic of the Congo. The highest peak of the Ruwenzori reaches , and the range' .... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
East African Rift
The East African Rift (EAR) or East African Rift System (EARS) is an active continental rift zone in East Africa. The EAR began developing around the onset of the Miocene, 22–25 million years ago. In the past it was considered to be part of a larger Great Rift Valley that extended north to Asia Minor. A narrow zone, the rift is a developing divergent tectonic plate boundary where the African Plate is in the process of splitting into two tectonic plates, called the Somali Plate and the Nubian Plate, at a rate of 6-7 mm per year. The rift system consists of three microplates, the Victoria Microplate to the north, and the Rovuma and Lwandle microplates to the south. The Victoria Microplate is rotating anti-clockwise with respect to the African plate. Its rotation is caused by the configuration of mechanically weaker and stronger lithospheric regions in the EARS. Extent A series of distinct rift basins, the East African Rift System extends over thousands of kilometers. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Donaldson Smith
Arthur Donaldson Smith (1866–1939) was an American physician, hunter, and explorer of Africa. In the 1890s he made a geological expedition to Lake Rudolph (now Lake Turkana), passing through what was then Somaliland, southern Ethiopia and Kenya. In order to visit Ethiopia, he had to get permission from Menelik II. The trip lasted 18 months and took place between 1894 and 1895. In 1897 he published a book about his trip called, ''Through Unknown African Countries: the First Expedition from Somaliland to Lake Rudolf''. In 1895 three new species of reptiles endemic to the Horn of Africa were named in his honor by Belgian-British herpetologist George Albert Boulenger: ''Zamenis smithi'' (now '' Platyceps brevis smithi)'', ''Hemidactylus smithi'', and ''Pseuderemias smithii''.Beolens B, Watkins M, Grayson M. 2011.

Margherita Of Savoy
Margherita of Savoy (''Margherita Maria Teresa Giovanna''; 20 November 1851 – 4 January 1926) was Queen of Italy by marriage to Umberto I. Life Early life Margherita was born to Prince Ferdinand of Savoy, Duke of Genoa and Princess Elisabeth of Saxony. Her father died in 1855, and her mother remarried morganatically to Major Nicholas Bernoud, Marchese di Rapallo. She was educated by countess Clelia Monticelli di Casalrosso and her Austrian governess Rosa Arbesser. Reportedly, she was given a more advanced education than most princesses at the time, and displayed a great deal of intellectual curiosity.Dizionario Biografico degli Italiani - Volume 70 (2008) As a person, she was described as sensitive, proud and with a strong force of will without being hard, as well as having the ability to be charming when she chose to. As to her appearance, she was described as a tall, stately blonde, but she was not regarded as a beauty. Initially, she was suggested to marry Prince Charles ...

Lake Abaya
Lake Abaya (Amharic: አባያ ሐይቅ) is a lake in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. It is located in the Main Ethiopian Rift, east of the Guge Mountains. The town of Arba Minch lies on its southwestern shore, and the southern shores are part of the Nechisar National Park. Just to the south is Lake Chamo. Savanna, known for its wildlife and birdlife, surrounds the lake, which is also fished by local people. According to the Ethiopian Department of Fisheries and Aquaculture, 412 tonnes of fish are landed each year, which the department estimates is 69% of its sustainable amount. Lake Abaya is 60 kilometers long and 20 wide, with a surface area of 1162 square kilometers.Baxter, R. M. ''Lake Morphology and Chemistry.'' in Taylor, W.D. and Tudorancea, C., eds.

Vittorio Bottego
Vittorio Bottego (; Parma, 29 July 1860 – Dhaga Roba, 17 March 1897) was an Italian army officer and one of the first Western explorers of Jubaland in the Horn of Africa (now part of Gidami, West Wellega Ethiopia), where he led two expeditions. He was an artillery captain in the Italian Army. Expeditions In his first expedition Bottego concentrated on tracing the channels of the tributaries of the Ganale Doria, that he named after the Italian biologist Giacomo Doria. With Captain Matteo Grixoni, Bottego left Bardera on 30 September 1892, with one hundred and twenty-four men. They reached the Shebeli River at Imi on 7 November. After eight days they crossed the river, entering the country of the Arsi Oromo, who proved hostile to Bottego. He passed through Arkebla and reached the Ganale Guracha ("Black Ganale") on 11 December, along whose banks he led his men upstream for 20 days. Concluding that this was not the main stream of the river, Bottego left the river in a west-sou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hot Springs
A hot spring, hydrothermal spring, or geothermal spring is a spring produced by the emergence of geothermally heated groundwater onto the surface of the Earth. The groundwater is heated either by shallow bodies of magma (molten rock) or by circulation through faults to hot rock deep in the Earth's crust. In either case, the ultimate source of the heat is radioactive decay of naturally occurring radioactive elements in the Earth's mantle, the layer beneath the crust. Hot spring water often contains large amounts of dissolved minerals. The chemistry of hot springs ranges from acid sulfate springs with a pH as low as 0.8, to alkaline chloride springs saturated with silica, to bicarbonate springs saturated with carbon dioxide and carbonate minerals. Some springs also contain abundant dissolved iron. The minerals brought to the surface in hot springs often feed communities of extremophiles, microorganisms adapted to extreme conditions, and it is possible that life on Earth had its ...

Ruwenzori Mountains
The Ruwenzori, also spelled Rwenzori and Rwenjura, are a range of mountains in eastern equatorial Africa, located on the border between Uganda and the Democratic Republic of the Congo. The highest peak of the Ruwenzori reaches , and the range's upper regions are permanently snow-capped and glaciated. Rivers fed by mountain streams form one of the sources of the Nile. Because of this, European explorers linked the Ruwenzori with the legendary Mountains of the Moon, claimed by the Greek scholar Ptolemy as the source of the Nile. Virunga National Park in eastern DR Congo and Rwenzori Mountains National Park in southwestern Uganda are located within the range. Geology The mountains formed about three million years ago in the late Pliocene epoch and are the result of an uplifted block of crystalline rocks including gneiss, amphibolite, granite and quartzite. The Rwenzori mountains are the highest non-volcanic, non-orogenic mountains in the world. This uplift divided the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basement (geology)
In geology, basement and crystalline basement are crystalline rocks lying above the mantle and beneath all other rocks and sediments. They are sometimes exposed at the surface, but often they are buried under miles of rock and sediment. The basement rocks lie below a sedimentation, sedimentary platform (geology), platform or cover, or more generally any rock below sedimentary rocks or sedimentary basins that are metamorphic rock, metamorphic or Igneous rock, igneous in origin. In the same way, the sediments or sedimentary rocks on top of the basement can be called a "cover" or "sedimentary cover". Crustal rocks are modified several times before they become basement, and these transitions alter their composition. Continental crust Basement rock is the thick foundation of ancient, and oldest, metamorphic and igneous rock that forms the Crust (geology), crust of continents, often in the form of granite. Basement rock is contrasted to overlying sedimentary rocks which are laid down ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
