Extreme North Province
The Far North Region, also known as the Extreme North Region (from french: Région de l'Extrême-Nord), is the northernmost constituent province of the Republic of Cameroon. It borders the North Region to the south, Chad to the east, and Nigeria to the west. The capital is Maroua. The province is one of Cameroon's most culturally diverse. Over 50 different ethnic groups populate the area, including the Shuwa Arabs, Fulani, and Kapsiki. Most inhabitants speak the Fulani language Fulfulde, Chadian Arabic, and French. Geography Land Sedimentary rock such as alluvium, clay, limestone, and sandstone forms the greatest share of the Far North's geology. These deposits follow the province's rivers, such as the Logone and Mayo Tsanaga, as they empty into Lake Chad to the north. At the province's south, a band of granite separates the sedimentary area from a zone of metamorphic rock to the southwest. This latter region includes deposits of gneiss, mica, and schists.

Departments Of Cameroon
The Regions of Cameroon are divided into 58 divisions or departments. The divisions are further sub-divided into sub-divisions (''arrondissements'') and districts. The divisions are listed below, by province. The constitution divides Cameroon into 10 semi-autonomous regions, each under the administration of an elected Regional Council. A presidential decree of 12 November 2008 officially instigated the change from provinces to regions. Each region is headed by a presidentially appointed governor. These leaders are charged with implementing the will of the president, reporting on the general mood and conditions of the regions, administering the civil service, keeping the peace, and overseeing the heads of the smaller administrative units. Governors have broad powers: they may order propaganda in their area and call in the army, gendarmes, and police. All local government officials are employees of the central government's Ministry of Territorial Administration, from which loca ...

Baggara
The Baggāra ( ar, البَقَّارَة "heifer herder") or Chadian Arabs are a nomadic confederation of people of mixed Arab and Arabized indigenous African ancestry, inhabiting a portion of the Sahel mainly between Lake Chad and the Nile river near south Kordofan, numbering over six million. They are known as Baggara and Abbala in Sudan, and as Shuwa Arabs in Cameroon, Nigeria and Western Chad. The term Shuwa is said to be of Kanuri origin. The Baggāra mostly speak their distinct dialect, known as Chadian Arabic. However the Baggāra of Southern Kordofan, due to contact with the sedentary population and the Sudanese Arab camel herders of Kordofan, has led to some Sudanese Arabic influence on the dialect of that zone. They also have a common traditional mode of subsistence, nomadic cattle herding, although nowadays many lead a settled existence. Nevertheless, collectively they do not all necessarily consider themselves one people, i.e., a single ethnic group. The term "ba ...

Granite
Granite () is a coarse-grained ( phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or '' granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is near ...

Lake Chad
Lake Chad (french: Lac Tchad) is a historically large, shallow, endorheic lake in Central Africa, which has varied in size over the centuries. According to the ''Global Resource Information Database'' of the United Nations Environment Programme, it shrank by as much as 95% from about 1963 to 1998. The lowest area was in 1986, at , but "the 2007 (satellite) image shows significant improvement over previous years." Lake Chad is economically important, providing water to more than 30 million people living in the four countries surrounding it (Chad, Cameroon, Niger, and Nigeria) on the central part of the Sahel. It is the largest lake in the Chad Basin. Geography and hydrology The freshwater lake is located in the Sahelian zone of West-central Africa. It is located in the interior basin which used to be occupied by a much larger ancient sea sometimes called Mega Chad. The lake is historically ranked as one of the largest lakes in Africa. Its surface area varies by season as well a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Logone River
The Logon or Logone River is a major tributary of the Chari River. The Logone's sources are located in the western Central African Republic, northern Cameroon, and southern Chad. It has two major tributaries: the Pendé River (Eastern Logone) in the prefecture Ouham-Pendé in the Central African Republic and the Mbéré River (Western Logone) at the east of Cameroon. Many swamps and wetlands surround the river. Settlements on the river include Kousseri, Cameroon's northernmost city, and Chad's capital city, N'Djaména, which is located at the spot where the Logone empties into the Chari River. The Logone forms part of the international border between Chad and Cameroon. Hydrometry The flow of the river has been observed over 38 years (1951–84) in Bongor a town in Chad downstream of the union with the Pendé about above the mouth into the Chari. The Bongor observed average annual flow during this period was fed by an area of about approximately 94.5% of the total c ...

Sandstone
Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) silicate grains. Sandstones comprise about 20–25% of all sedimentary rocks. Most sandstone is composed of quartz or feldspar (both silicates) because they are the most resistant minerals to weathering processes at the Earth's surface. Like uncemented sand, sandstone may be any color due to impurities within the minerals, but the most common colors are tan, brown, yellow, red, grey, pink, white, and black. Since sandstone beds often form highly visible cliffs and other topographic features, certain colors of sandstone have been strongly identified with certain regions. Rock formations that are primarily composed of sandstone usually allow the percolation of water and other fluids and are porous enough to store large quantities, making them valuable aquifers and petroleum reservoirs. Quartz-bearing sandstone can be changed into quartzite through metamorphism, usually relate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolin, Al2 Si2 O5( OH)4). Clays develop plasticity when wet, due to a molecular film of water surrounding the clay particles, but become hard, brittle and non–plastic upon drying or firing. Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clay is the oldest known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been dated to around 14,000 BC, and clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, oft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alluvium
Alluvium (from Latin ''alluvius'', from ''alluere'' 'to wash against') is loose clay, silt, sand, or gravel that has been deposited by running water in a stream bed, on a floodplain, in an alluvial fan or beach, or in similar settings. Alluvium is also sometimes called alluvial deposit. Alluvium is typically geologically young and is not consolidated into solid rock. Sediments deposited underwater, in seas, estuaries, lakes, or ponds, are not described as alluvium. Floodplain alluvium can be highly fertile, and supported some of the earliest human civilizations. Definitions The present consensus is that "alluvium" refers to loose sediments of all types deposited by running water in floodplains or in alluvial fans or related landforms. However, the meaning of the term has varied considerably since it was first defined in the French dictionary of Antoine Furetière, posthumously published in 1690. Drawing upon concepts from Roman law, Furetière defined ''alluvio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
French Language
French ( or ) is a Romance languages, Romance language of the Indo-European languages, Indo-European family. It descended from the Vulgar Latin of the Roman Empire, as did all Romance languages. French evolved from Gallo-Romance, the Latin spoken in Gaul, and more specifically in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien) largely supplanted. French was also substratum, influenced by native Celtic languages of Northern Roman Gaul like Gallia Belgica and by the (Germanic languages, Germanic) Frankish language of the post-Roman Franks, Frankish invaders. Today, owing to France's French colonial empire, past overseas expansion, there are numerous French-based creole languages, most notably Haitian Creole language, Haitian Creole. A French-speaking person or nation may be referred to as Francophone in both English and French. French is an official language in ...

Chadian Arabic
Chadian Arabic ( ar, لهجة تشادية), also known as Shuwa Arabic, Baggara Arabic, Western Sudanic Arabic, or West Sudanic Arabic (WSA), is a variety of Arabic and the first language of 1.6 million people, both town dwellers and nomadic cattle herders. The majority of its speakers live in southern Chad. Its range is an east-to-west oval in the Sahel. Nearly all of this territory is within Chad or Sudan. It is also spoken elsewhere in the vicinity of Lake Chad in the countries of Cameroon, Nigeria, Niger. Finally, it is spoken in slivers of the Central African Republic, and South Sudan. In addition, this language serves as a lingua franca in much of the region. In most of its range, it is one of several local languages and often not among the major ones. Name and origin This language does not have a native name shared by all its speakers, beyond "Arabic". It arose as the native language of nomadic cattle herders (''baggāra'', Standard Arabic ''baqqāra'' , means ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
