Description
Summary:The Umm Gheig Formation belongs to the Abu Ziran Group of the Central Eastern Desert of Egypt. Rocks of this formation are originally derived from basalt, andesite and subordinate rhyolite. Although the formation includes two pétrographie associations suffering different grades of metamorphism, however, they have close consanguineous magmatic relationship. It is suggested that these associations belonging to tholeiitic magma type which are tectonically emplaced as island arc.
