Nuba Mountains, also known as the Nuba Hills, are situated around 500 km southwest to Khartoum City covering an area of approximately 140,000 km2 . The Nuba Mountains area is made of the Precambrian basement rocks bounded by the Mesozoic and Cenozoic sedimentary rocks in a number of grabens. Two divisions of the basement rocks have been recognized in the Nuba Hills: 1) low-grade metamorphic rocks of volcano-sedimentary association in the east, and 2) high-grade metamorphic rocks in the west, covered by thick Quaternary sedimentary deposits in many places. Two cycles of structures are reported in the crystalline rocks of the Nuba Hills. Older cycle predominates in the central part of the Hills and is composed of the high-grade metamorphic rock (amphibolite facies) of migmatite gneisses and crystalline schists. A younger cycle is represented by low-grade metamorphism (green schist facies) of metavolcanics and metasediments. These rocks unconformably cover the high-grade metamorphic rocks of the older cycle and are restricted principally to the western and eastern portions of the Nuba Hills. Both younger and older cycles are encroached by post-tectonic intrusive rocks of different types varying between granitoids and gabbroids. Both intrusive rocks and their associated extrusive equivalents are arranged in three major belts: northeastern, central and southwestern belts. Northeastern belt comprises of a number of scattered granitic and syenitic intrusions in Kadero, Jebel Ed Dair, Jebel Dumbier, Jugob Al Kharasana, El Semieh, and Tibna areas.
