These rifts follow similar trends, and terminate in a line at their northwestern ends. Probably this line is an extension of the Central African Shear Zone through the Sudan. [2] The rift basin is formed by the junction of the Umm Rubaba grabens, which extends in a NW direction, and the White Nile graben, which extends in a N to NW direction. [3]
The White Nile (Arabic: النيل الأبيض an-nīl al-'abyaḍ) is a river in Africa, the minor of the two main tributaries of the Nile, the larger being the Blue Nile. [4] The name "White" comes from the clay sediment carried in the water that changes the water to a pale color.
The lake bed sits upon a rift valley that is slowly being pulled apart, causing volcanic activity in the area. The world's tenth-largest island in a lake , Idjwi , lies in Lake Kivu. Settlements on the lake's shore include Bukavu , Kabare , Kalehe , Sake and Goma in the Democratic Republic of the Congo, and Gisenyi , Kibuye , and Cyangugu in ...
The West and Central African Rift System, with the Central African Shear Zone labeled CASZ. The West and Central African Rift System (WCARS) is a rift system composed of two coeval Cretaceous rift sub-systems, the West African Rift sub-system (WAS) and the Central African Rift sub-system (CAS). [1]
The rift jump coincided with the maximum output of the Deccan Traps, [8] and volcanics found on the Seychelles Plateau have also been linked with this event. [5] This has led to suggestions that the initiation of the Reunion plume caused rifting to jump to its current location.
The Saharan Metacraton between the Hoggar Mountains and the Nile river consists of an Archaean-Palaeoproterozoic basement overprinted by Pan-African granitoids. [14] The Rokelide Belt passes along the western margin of the Archaean Man Shield in the southern West African Craton. It was intensely deformed during the Pan-African orogeny with a ...
The Blue Nile connected to the main Nile during the 70,000–80,000 years B.P. wet period. The White Nile system in Bahr El Arab and White Nile Rifts remained a closed lake until the connection of the Victoria Nile to the main system some 12,500 years ago during the African humid period.
The Albertine Rift is the western branch of the East African Rift, covering parts of Uganda, the Democratic Republic of the Congo (DRC), Rwanda, Burundi and Tanzania. It extends from the northern end of Lake Albert to the southern end of Lake Tanganyika. The geographical term includes the valley and the surrounding mountains. [1]
