Contributions to the study of Egyptian (UAR) iron ores

Essam E. El-Hinnawi

Oolitic iron ores of Aswan, in the middle of the Cretaceous Nubian sandstone series, belong to the hematitic oxide facies. In phosphorus content and ratio of Ca to P, they resemble Wabana ores, and differ from minette and Clinton types. Iron is believed to have been transported as hydrosol adsorbed on clay minerals, as in modern Nile flood waters, and deposited in mildly agitated waters, mixed marine and fresh. The Eocene ores of Bahariya oasis were related to Tertiary volcanism, and the iron was most probably transported in carbonated waters. The phosphorus content is independent of the CaO content.
