In Egypt, the strata of major hydrogeological interest are composed of a sandstone complex ranging from Cambrian to Upper Cretaceous in age. This sandstone complex, commonly known as the Nubian Sandstone, has a thickness varying from less than m to more than m and rests directly on Precambrian by: Similarly, FAO () estimated that the Nubian aquifer in the Sudan contains ∼33, km 3 of groundwater but only km 3 of this resource is recoverable. In contrast, Ibrahim () estimated the total volume of groundwater in the Nubian aquifer in northwestern Sudan Cited by: 8. Of these the most important aquifer is the Nubian Sandstone Formation. It occupies ab13^ of thp total surface area of Sudan. Fortunately most of this is situated North of 12' N whore water is needed most. These different formations constitute the major basins of ^u either in a simple form i,e. one geological formation, or in a Com. Figure 2: Regional Geology of Nubian Sandstone Aquifer (CEDARE, ). Precambrian Basement outcrops immediately to the South, East, and Southwest of the Basin. Local exposures are also found at Oweinat area at the border between Egypt Libya, and Sudan. The Basement rocks are dominated by granites and granodiorites in addition to.
The Nubian Sandstone Formation is a major regional aquifer (see the Hydrogeology of Sudan page for more detail). In South Sudan it is largely overlain by unconsolidated deposits, which vary in thickness (see above).Border countries: Sudan, Ethiopia, Kenya, Uganda, the Democratic Republic of the Congo, the Central African Republic. The countries of Northeast Africa, Egypt, Libya, Chad and Sudan share The Nubian Sandstone Aquifer System (NSAS), which represents a huge fresh water reserve. The four ountries have expressed their interest to share their experiences and to developc this regional Aquifer Size: 1MB.

The oldest geological unit is a highly weathered unfoliated porphyritic granite outcropping at Jebel Aklaiyit and belonging to the Early Cambrian Basement Complex of the Sudan. These basement rocks are overlain by a series of Mesozoic clastic sediments, generally known as Nubian Sandstone Formation and considered to be of Cretaceous age in the region of Gedaref-Showak (Omer ).Cited by: 3.
The Nubian Sandstone Aquifer System (NSAS) is the world's largest known fossil water aquifer system. It is located underground in the Eastern end of the Sahara Desert and spans the political boundaries of four countries in north-eastern Africa. NSAS covers a land area spanning just over two million km 2, including north-western Sudan, north-eastern Chad, south-eastern Libya, and most of Egypt.
