Description
Summary:Microfacial analysis, based on six stratigraphic sections, were carried out to the Duwi (Phosphate) Formation at the coastal plain of Quseir-Safaga along the Red Sea coast. The study showed that the main rock types are: phosphorite, organic-rich shale, siliceous claystone, glauconitic sandstone, chert, dolomite, and oyster limestone. Detailed field and microfacial investigations of these rock types were done. The paleogeographical distribution of the Duwi (Phosphate) Formation was found to be influenced by biological and chemical parameters which was necessary for the precipitation of calcium phosphates. Other factors controlling the areal extent includt water depth, wave base and current velocity.
