Taoudeni Basin
The Taoudeni Basin is a major Sedimentary basin in West Africa, named after the Taoudenni village in northern Mali. It covers large parts of the West African craton in Mauritania and Mali. It is of considerable interest due to its possible reserves of oil. In addition to its economic importance, the basin contains scientifically important fossils from the Late Mesoproterozoic and Early Neoproterozoic eras, which correspond to a time interval known as the Boring Billion. Description The Taoudeni is the largest sedimentary basin in Northwest Africa, formed during the Middle to Late Proterozoic. It continued to subside until the Middle Paleozoic, when Hercynian deformation and uplift occurred. It contains up to of Late Precambrian and Paleozoic sediments. Exploratory drilling since the 1980s has found indications of petroleum in the Late Precambrian, Silurian and Late Devonian formations. Sediments are thicker in the western half of the basin.

Precambrian
The Precambrian (or Pre-Cambrian, sometimes abbreviated pꞒ, or Cryptozoic) is the earliest part of Earth's history, set before the current Phanerozoic Eon. The Precambrian is so named because it preceded the Cambrian, the first period of the Phanerozoic Eon, which is named after Cambria, the Latinised name for Wales, where rocks from this age were first studied. The Precambrian accounts for 88% of the Earth's geologic time. The Precambrian is an informal unit of geologic time, subdivided into three eons ( Hadean, Archean, Proterozoic) of the geologic time scale. It spans from the formation of Earth about 4.6 billion years ago ( Ga) to the beginning of the Cambrian Period, about million years ago ( Ma), when hard-shelled creatures first appeared in abundance. Overview Relatively little is known about the Precambrian, despite it making up roughly seven-eighths of the Earth's history, and what is known has largely been discovered from the 1960s onwards.

Landforms Of Algeria
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodies and sub-surface features. Mountains, hills, plateaux, and plains are t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Mauritania
The geology of Mauritania is built on more than two billion year old Archean crystalline basement rock in the Reguibat Shield of the West African Craton, a section of ancient and stable continental crust. Mobile belts and the large Taoudeni Basin formed and filled with sediments in the connection with the Pan-African orogeny mountain building event 600 million years ago and a subsequent orogeny created the Mauritanide Belt. In the last 251 million years, Mauritania has accumulated additional sedimentary rocks during periods of marine transgression and sea level retreat. The arid country is 50% covered in sand dunes and has extensive mineral resources, although iron plays the most important role in the economy. Stratigraphy, tectonics and geologic history The oldest rocks in Mauritania date to the Archean, over two billion years old in the Reguibat Shield of the West African Craton. The extremely old crystalline basement rock of the shield is almost entirely Neoarchean age and me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Mali
Mali is a landlocked nation in West Africa, located southwest of Algeria, extending south-west from the southern Sahara Desert through the Sahel to the Sudanian savanna zone. Mali's size is 1,240,192 square kilometers. Desert or semi-desert covers about 65 percent of Mali's total area (1,240,192 square kilometers). The Niger River creates a large and fertile inland delta as it arcs northeast through Mali from Guinea before turning south and eventually emptying into the Gulf of Guinea. The territory encompasses three natural zones: the southern cultivated Sudanese zone, central semi-desert Sahelian zone, and northern desert Saharan zone. The terrain is primarily savanna in the south and flat to rolling plains or high plateau (200–500 meters in elevation) in the north. There are rugged hills in the northeast, with elevations of up to 1,000 meters. The Niger (with 1,693 kilometers in Mali) and Senegal are Mali's two largest rivers. The Niger is generally described as Mali's ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geology Of Algeria
The geology of Algeria is diverse; the country divides into three different tectono-stratigraphic domains. In the south and west is the West African Craton which consists of Precambrian granitic basement and surrounding Neoproterozoic mobile belts. Further south the Tuareg Shield comprises the Hoggar, Adrar des Iforas and Air sub-shields which have each been affected by tectono-thermal events touching much of the continent. In the north are the Alpine chain mountains with a succession of folded and over-thrust strata. Economic geology The production of oil and gas is important to Algeria's economy, being Africa's main producer of the latter. Its reserves were estimated at 4.502 trillion m3 at the end of 2008. Productive fields are found in anticlines, faulted anticlines or domes; the reservoirs being in Cambro-Ordovician, Triassic, Devonian, and Carboniferous sandstones. Caprocks include Triassic evaporites and Carboniferous to Devonian shales. The major source rocks fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedimentary Basins Of Africa
Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation. Sedimentation is the collective name for processes that cause these particles to settle in place. The particles that form a sedimentary rock are called sediment, and may be composed of geological detritus (minerals) or biological detritus (organic matter). The geological detritus originated from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus was formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies (marine snow). Sedimentation may also occur as dissolved minerals precipitate from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
