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 Alpine orogeny is caused by the continents Africa, Arabia and India and the small Cimmerian Plate colliding (from the south) with Eurasia in the north. Convergent movements between the tectonic plates (the African Plate, the Arabian Plate and the Indian Plate from the south, the Eurasian Plate and the Anatolian Sub-Plate from the north, and many smaller plates and microplates) had already ...
In the past, Lake Kivu drained toward the north, contributing to the White Nile. About 13,000 to 9,000 years ago, volcanic activity blocked Lake Kivu's outlet to the watershed of the Nile. [ 5 ] The volcanism produced mountains, including the Virungas , which rose between Lake Kivu and Lake Edward, to the north. [ 6 ]
Map of Nile tributaries in modern Sudan, showing the Yellow Nile The Nile represented in an ancient Roman mosaic found from the ruins of Pompeii. The Yellow Nile is a former tributary that connected the Ouaddaï highlands of eastern Chad to the Nile River Valley c. 8000 to c. 1000 BCE . [ 49 ]
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 Greater Upper Nile (Arabic: منطقة أعالي النيل, romanized: A'Ali An Nil) is a region of northeastern South Sudan. [1] It is named for the White Nile (it is its lowest portion in South Sudan), a tributary of the Nile River in North and East Africa .
A map of East Africa showing some of the historically active volcanoes (as red triangles) and the Afar Triangle (shaded at the center), which is a so-called triple junction (or triple point) where three plates are pulling away from one another: the Arabian plate and two parts of the African plate—the Nubian and Somali—splitting along the East African Rift Zone Main rift faults, plates ...
