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 Ansar–Khatmiyya rivalry, [1] [2] [3] also known as al-Mahdi and al-Mirghani rivalry or the Two Sayyids rivalry, [4] was a sectarian division in Sudan that shaped the country's political landscape after the end of the Mahdist State in 1899 and until the Kizan era in 1989.
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 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]
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 ]
The CASZ was formerly thought to extend eastward only to the Darfur region of western Sudan. [3] It is now interpreted to extend into central and eastern Sudan, with a total length of 4,000 km. [1] In the Sudan, the shear zone may have acted as a structural barrier to development of deep Cretaceous-Tertiary sedimentary basins in the north of the area.

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.
