Yubdo (woreda)
Yubdo or Jubdo is a woreda in Oromia Region, Ethiopia. Part of the West Welega Zone, Yubdo is bordered on the south by Nole Kaba, on the west by Kelem Welega Zone, on the northwest by Ayra Guliso, on the northeast by Lalo Asabi, on the east by Gimbi, and on the southeast by Haru. The administrative center of this woreda is Yubdo; other towns in Yubdo include Ganji. Rivers in this woreda include the Karsa, a tributary of the Kobara. Coffee is an important cash crop of this woreda. Over 50 square kilometers are planted with this crop. Platinum occurs in this woreda, developed on serpentinized dunite, locally named Birbirite, after the Birbir River; the platinum probably being remobilized and concentrated by hydrothermal alteration in conjunction with shearing. The total reserves are about 12 tons, with an average grade of 0.34 gram/ton. An Italian miner named Alberto Prasso received a concession to mine this deposit in 1924. Prasso established a company in Paris, ''So ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Districts Of Ethiopia
Districts of Ethiopia, also called woredas ( am, ወረዳ; ''woreda''), are the third level of the administrative divisions of Ethiopia – after ''zones'' and the '' regional states''. These districts are further subdivided into a number of wards called ''kebele'' neighbourhood associations, which are the smallest unit of local government in Ethiopia. Overview Districts are typically collected together into zones, which form a region; districts which are not part of a zone are designated Special Districts and function as autonomous entities. Districts are governed by a council whose members are directly elected to represent each ''kebele'' in the district. There are about 670 rural districts and about 100 urban districts. Terminology varies, with some people considering the urban units to be ''woreda'', while others consider only the rural units to be ''woreda'', referring to the others as urban or city administrations. Although some districts can be traced back to earli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Platinum
Platinum is a chemical element with the symbol Pt and atomic number 78. It is a dense, malleable, ductile, highly unreactive, precious, silverish-white transition metal. Its name originates from Spanish , a diminutive of "silver". Platinum is a member of the platinum group of elements and group 10 of the periodic table of elements. It has six naturally occurring isotopes. It is one of the rarer elements in Earth's crust, with an average abundance of approximately 5 μg/kg. It occurs in some nickel and copper ores along with some native deposits, mostly in South Africa, which accounts for ~80% of the world production. Because of its scarcity in Earth's crust, only a few hundred tonnes are produced annually, and given its important uses, it is highly valuable and is a major precious metal commodity. Platinum is one of the least reactive metals. It has remarkable resistance to corrosion, even at high temperatures, and is therefore considered a noble metal. Consequent ...

Islam In Ethiopia
Islam is the second-largest religion in Ethiopia behind Christianity, with 31.3 to 35.9 percent of the total population of around 113.5 million people professing the religion as of 2022. Islam in Ethiopia dates back to the founding of the religion; in 615, when a group of Muslims were counseled by Muhammad to escape persecution in Mecca and Migration to Abyssinia, travel to Ethiopia via modern-day Eritrea, which was ruled by Najashi, a pious Christian king. It is agreed by Islamic scholars that Najashi First Hejira, gave shelter to the Muslim refugees around 615–616 at Axum. Bilal ibn Ribah, the first Muezzin, the person chosen to call the faithful to prayer, and one of the foremost companions of Muhammad, was born in Mecca to an Abyssinian (Ethiopian) mother. Introduction Islam was in 2007 the second largest religion in Ethiopia with over 33.9% of the population. The faith arrived in Tigray Region, Tigray, north of Ethiopia, at an early date, shortly before the Hijra (Isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ethiopian Orthodox Christianity
The Ethiopian Orthodox Tewahedo Church ( am, የኢትዮጵያ ኦርቶዶክስ ተዋሕዶ ቤተ ክርስቲያን, ''Yäityop'ya ortodoks täwahedo bétäkrestyan'') is the largest of the Oriental Orthodox Churches. One of the few Christian churches in sub-Saharan Africa originating before European colonization of the continent, the Ethiopian Orthodox Tewahedo Church dates back to the acceptance of Christianity by the Kingdom of Aksum in 330, and has between 36 million and 49.8 million adherents in Ethiopia. It is a founding member of the World Council of Churches. The Ethiopian Orthodox Tewahedo Church is in communion with the other Oriental Orthodox churches (the Eritrean Orthodox Tewahedo Church, the Coptic Orthodox Church of Alexandria, the Malankara Orthodox Syrian Church, the Armenian Apostolic Church, and the Syriac Orthodox Church).

P'ent'ay
P'ent'ay (from Ge'ez: ) is an originally Amharic–Tigrinya language term for Pentecostal and other Eastern-oriented Protestant Christians within Ethiopia and Eritrea, and the Ethiopian and Eritrean diaspora. Today, the term refers to all Evangelical Protestant denominations and organisations in Ethiopian and Eritrean societies as Ethiopian–Eritrean Evangelicalism or the Ethiopian–Eritrean Evangelical Church. Sometimes the denominations and organizations are also known as Wenigēlawī (from Ge'ez: ). Ethiopian and Eritrean Protestant Christianity was originally introduced as the result of American and European Protestant missionary work, which began in the 19th century, among various peoples including Christians schismed from the Orthodox Tewahedo churches, other branches of Christianity, or converted from non-Christian religions or traditional practices. Since the creation of P'ent'ay churches and organisations, prominent movements among them have been Pentecostalism, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shear (geology)
Boudinaged quartz vein (with strain fringe) showing ''Fault (geology)">sinistral shear sense'', Starlight Pit, Fortnum Gold Mine, Western Australia In geology, shear is the response of a rock to deformation usually by compressive stress and forms particular textures. Shear can be homogeneous or non-homogeneous, and may be pure shear or simple shear. Study of geological shear is related to the study of structural geology, rock microstructure or rock texture and fault mechanics. The process of shearing occurs within brittle, brittle-ductile, and ductile rocks. Within purely brittle rocks, compressive stress results in fracturing and simple faulting. Rocks Rocks typical of shear zones include mylonite, cataclasite, S-tectonite and L-tectonite, pseudotachylite, certain breccias and highly foliated versions of the wall rocks. Shear zone A shear zone is a tabular to sheetlike, planar or curviplanar zone composed of rocks that are more highly strained than rocks adjacent to ...

Hydrothermal Alteration
Metasomatism (from the Greek μετά ''metá'' "change" and σῶμα ''sôma'' "body") is the chemical alteration of a rock by hydrothermal and other fluids. It is the replacement of one rock by another of different mineralogical and chemical composition. The minerals which compose the rocks are dissolved and new mineral formations are deposited in their place. Dissolution and deposition occur simultaneously and the rock remains solid. Synonyms to the word metasomatism are metasomatose and metasomatic process. The word metasomatose can also be used as a name for specific varieties of metasomatism (for example '' Mg-metasomatose'' and '' Na-metasomatose''). Metasomatism can occur via the action of hydrothermal fluids from an igneous or metamorphic source. In the igneous environment, metasomatism creates skarns, greisen, and may affect hornfels in the contact metamorphic aureole adjacent to an intrusive rock mass. In the metamorphic environment, metasomatism is created by mass ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birbir River
The Birbir River of southwestern Ethiopia is a tributary of the Baro River, which it creates when it joins the Gebba at latitude and longitude . It is politically important because its course defines part of the boundary between the Mirab Welega and Illubabor Zones of the Oromia Region. Richard Pankhurst notes that the Birbir is economically important for the discovery in 1904 of deposits of platinum along its course.Richard Pankhurst, ''Economic History of Ethiopia'' (Addis Ababa: Haile Selassie I University, 1968), pp. 231, 234.

Dunite
Dunite (), also known as olivinite (not to be confused with the mineral olivenite), is an intrusive igneous rock of ultramafic composition and with phaneritic (coarse-grained) texture. The mineral assemblage is greater than 90% olivine, with minor amounts of other minerals such as pyroxene, chromite, magnetite, and pyrope. Dunite is the olivine-rich endmember of the peridotite group of mantle-derived rocks. Dunite and other peridotite rocks are considered the major constituents of the Earth's mantle above a depth of about . Dunite is rarely found within continental rocks, but where it is found, it typically occurs at the base of ophiolite sequences where slabs of mantle rock from a subduction zone have been thrust onto continental crust by obduction during continental or island arc collisions (orogeny). It is also found in alpine peridotite massifs that represent slivers of sub-continental mantle exposed during collisional orogeny. Dunite typically undergoes retrograde metamorp ...

Serpentine Group
Serpentine subgroup (part of the kaolinite-serpentine group in the category of phyllosilicates) are greenish, brownish, or spotted minerals commonly found in serpentinite. They are used as a source of magnesium and asbestos, and as decorative stone. The name comes from the greenish colour and smooth or scaly appearance from the Latin , meaning "serpent rock". Serpentine subgroup is a set of common rock-forming hydrous magnesium iron phyllosilicate () minerals, resulting from the metamorphism of the minerals that are contained in mafic to ultramafic rocks. They may contain minor amounts of other elements including chromium, manganese, cobalt or nickel. In mineralogy and gemology, serpentine may refer to any of the 20 varieties belonging to the serpentine subgroup. Owing to admixture, these varieties are not always easy to individualize, and distinctions are not usually made. There are three important mineral polymorphs of serpentine: antigorite, lizardite and chrysotile. Serpen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
