Two kms north-east of Dahab, the northernmost remnant of emerged Pleistocene terraces display well preserved coral-reef and associated peri-reefal facies. The Scleractinian corals within the reef sequence display a series of diagenetic features formed by the alteration of the original micro-structures under different diagenetic conditions. Evidence from cement fabrics (aragonite and high-Mg calcite) suggests that the cementation took place exclusively in a phreatic marine environment. Meteoric diagenesis is indicated by traces of minor leaching and sparry calcite cement. Formation of microcrystalline dolomite and halite might take place in a sabkha environment. This suggests under various diagenetic alternation conditions.
