Africa - Metallic deposits: In North Africa reserves of iron ore are concentrated in the Atlas Mountains and in the western Sahara. Egypt, however, has medium-grade reserves, of which the most important are at Al-Baḥriyyah Oasis. The ore deposits in Morocco and Tunisia, which were once of considerable importance, have …
The mines of magnetite and hematite occupy some areas of the Eastern Desert at Wadi Abu Subeira, northeast of Aswan city which is a volcanic and tectonic area. It is one of the largest arc sedimentary rock sequence affected by faulting and folding due to repeated stages of deformation. The iron deposits in this area are of oolitic type and …
The ore body is mostly composed of quartz and iron oxides (magnetite, hematite, maghemite, goethite in different proportions), occurring as alternating iron- and silica-rich laminates. LA-ICP-MS U–Pb dating on zircons in schists from both the lower and upper layers of the orebody indicate a depositional age of ca. ∼560 Ma for iron deposits.
