Peritidal ferruginous microbialites form the main bulk of the Middle Eocene ironstone deposits of the Bahariya Depression, Western Desert, Egypt. They include ferruginous stromatolites and microbially coated grains (ferruginous oncoids and ooids). Th

The Umm Nar BIF was formed in a sedimentary environment. It is confined to an upper stratigraphic zone of pre-Pan-African metamorphosed shelf deposits. During the Pan-African deformational history, the BIF and the host metasediments were tectonically

Limestones and evaporites are the main rock types constituting the exposed Middle Miocene sediments of the Red Sea coastal zone between Quseir and Mersa Alam. These rocks represent typical conekarst and karst ridge landforms with minor surface and su

The sulfides and sulfur minerals of the Ranga occurrences form three geometric types: (a) strata-bound rhythmic type of pyrite/marcasite associated with cryptalgal calcite, barite, and quartz; (b) stratiform to strata-bound rhythmic type of sulfur as
