Bahr El Arab Rift
The Bahr el Arab rift is a major geological feature in the southwest Sudan. The Bahr el Arab rift is made up of the Baggara graben, between the Central African Republic and the Nuba Mountains to the east, and the Sudd graben further south. It terminates to the north on the faulted Mesozoic deposits south of the Darfur Dome. The Babanusa trough has extensive faulting, increasing towards the south, reaching a depth of 5 km at the Unity oil field and 11 km south of the Bentiu oil fields.

Graben
In geology, a graben () is a depressed block of the crust of a planet or moon, bordered by parallel normal faults. Etymology ''Graben'' is a loan word from German, meaning 'ditch' or 'trench'. The word was first used in the geologic context by Eduard Suess in 1883. The plural form is either ''graben'' or ''grabens''. Formation A graben is a valley with a distinct escarpment on each side caused by the displacement of a block of land downward. Graben often occur side by side with horsts. Horst and graben structures indicate tensional forces and crustal stretching. Graben are produced from parallel normal faults, where the displacement of the hanging wall is downward, while that of the footwall is upward. The faults typically dip toward the center of the graben from both sides. Horsts are parallel blocks that remain between graben; the bounding faults of a horst typically dip away from the center line of the horst. Single or multiple graben can produce a rift valley.

Central African Republic
The Central African Republic (CAR; ; , RCA; , or , ) is a landlocked country in Central Africa. It is bordered by Chad to the north, Sudan to the northeast, South Sudan to the southeast, the DR Congo to the south, the Republic of the Congo to the southwest, and Cameroon to the west. The Central African Republic covers a land area of about . , it had an estimated population of around million. , the Central African Republic is the scene of a civil war, ongoing since 2012. Most of the Central African Republic consists of Sudano-Guinean savannas, but the country also includes a Sahelo- Sudanian zone in the north and an equatorial forest zone in the south. Two-thirds of the country is within the Ubangi River basin (which flows into the Congo), while the remaining third lies in the basin of the Chari, which flows into Lake Chad.

Nuba Mountains
The Nuba Mountains ( ar, جبال النوبة), also referred to as the Nuba Hills, is an area located in South Kordofan, Sudan. The area is home to a group of indigenous ethnic groups known collectively as the Nuba peoples. In the Middle Ages, the Nuba mountains had been part of the Nubian kingdom of Alodia. In the 18th century, they became home to the kingdom of Taqali that controlled the hills of the mountains until their defeat by Mahdi Muhammad Ahmad. After the British defeated the Mahdi army, Taqali was restored as a client state. Infiltration of the Messiria tribe of Baggara Arabs has been influential in modern conflicts. Up to 1.5 million people live in the mountains mostly ethnic Nuba and small minority of Baggara. Geography The mountains cover an area roughly 64 km wide by 145 km long (40 by 90 miles), and are 450 to 900 meters (1,500 to 3,000 feet) higher in elevation than the surrounding plain. The mountains stretch for some 48,000 square kilometers (19,0 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesozoic
The Mesozoic Era ( ), also called the Age of Reptiles, the Age of Conifers, and colloquially as the Age of the Dinosaurs is the second-to-last era of Earth's geological history, lasting from about , comprising the Triassic, Jurassic and Cretaceous Period (geology), Periods. It is characterized by the dominance of archosaurian reptiles, like the dinosaurs; an abundance of conifers and ferns; a hot Greenhouse and icehouse earth, greenhouse climate; and the tectonic break-up of Pangaea. The Mesozoic is the middle of the three eras since Cambrian explosion, complex life evolved: the Paleozoic, the Mesozoic, and the Cenozoic. The era began in the wake of the Permian–Triassic extinction event, the largest well-documented mass extinction in Earth's history, and ended with the Cretaceous–Paleogene extinction event, another mass extinction whose victims included the non-avian dinosaurs, Pterosaur, pterosaurs, Mosasaur, mosasaurs, and Plesiosaur, plesiosaurs. The Mesozoic was a time of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Darfur Dome
Darfur Dome or Darfur Volcanic Province is an area of about 100x400 km in Western Sudan. As well as its best-known and central feature, Deriba Crater, it encompasses the surrounding Marra Mountains (Jebel Marra) and Tagabo Hills, both formed around 16–10 Ma., and the Meidob Hills, formed around 6.8 Ma. There are currently two competing theories concerning Darfur Dome’s formation. The conventional view is that magmatism is the product of a rising mantle plume, with active volcanism being triggered by stress resolution along the Central African Fault Zone. Evidence for a plume origin includes domal uplift, gravity anomalies, and low seismic velocity zones in the mantle, though there is disagreement over whether these indicate a discreet, narrow plume under the Darfur region or a broad superplume with conduits feeding several African hotspots. Recently, some scientists have argued for a tectonic origin in which lithospheric extension, asthenospheric shear, and small-scale ...

Unity Oil Field
The Unity oil field is a major oil field in the Ruweng Administrative Area, South Sudan. It lies to the north of the state capital Bentiu in Rubkona County. The oil field, and the Heglig field further north, were discovered by Chevron Corporation in 1982, and was to become one of the most productive fields in Sudan. Chevron spent almost $880 million in exploration, but suspended operations soon after the Second Sudanese Civil War (1983-2005) began. The trigger was the killing in 1984 of three Chevron workers by Anyanya II Anyanya II is the name taken in 1978 by a group of the 64 tribes of South Sudan dissidents who took up arms in All of Sudan. The name implies continuity with the Anyanya, or Anya-Nya, movement of the First Sudanese Civil War (1955-1972). When th ... rebels. Chevron demanded a special oilfield protection force in addition to the army. Dissatisfied with security, by 1988 Chevron had closed its operations in Unity province.

Bentiu
Bentiu, also spelled Bantiu, is a city in South Sudan and capital of the state of Unity State. Location Bentiu is located in Rubkona County, Unity State, in northern South Sudan, near the international border with the Republic of the Sudan. It lies approximately 654 kilometers (406 miles), by road, northwest of Juba, the capital and largest city in the country. Bentiu sits on the southern bank of the Bahr el Ghazal River that separates it from the town of Rubkona, which sits on the river's northern bank. The two towns are joined by the ''El Salaam Bridge'' that spans the river. This bridge, along with a market, was bombed and partially damaged by North Sudanese MiG-29 bomber airplanes on April 23, 2012, during the Heglig Crisis. At least three people were killed in the raid. Population , the population of Bentiu including entire Rubkona County Payams was estimated at about 100,230.

Geology Of South Sudan
The geology of South Sudan is founded on Precambrian igneous and metamorphic rocks, that cover 40 percent of the country's surface and underlie other rock units. The region was affected by the Pan-African orogeny in the Neoproterozoic and extensional tectonics in the Mesozoic that deposited very thick oil-bearing sedimentary sequences in rift basins. Younger basalts, sandstones and sediments formed in the last 66 million years of the Cenozoic. The discovery of oil in 1975 was a major factor in the Second Sudanese Civil War, leading up to independence in 2011. The country also has gold, copper, cobalt, zinc, iron, marble, limestone and dolomite. Stratigraphy & geologic history The oldest rocks in South Sudan are Precambrian gneiss, metasediments and basic volcanics that form the igneous and metamorphic basement rock that underlies the country and is exposed as 40 percent of its surface. Some Precambrian rocks may be well over two billion years old. However, in most cases they were re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
