MetadataShow full item record
The present paper deals with the geochemistry and origin of the Pan - African basement rocks, which covers about 825 km2 North of Abu El Tiyur area, in the Central Eastern Desert of Egypt. The petrochemical character of the spililics and spilitic diabase, under consideration, exhibits a tholciitic magma type suggesting that they form a part of the ophiolilic assemblage of Mid - oceanic ridge gcotcctonic environment. The petrochemical study of the magmatic arc suite reveals that their source is a low - potassium calc alkaline type similar to that of ensimatic island arc environments. Geochemically the late collision granitoids are of calc - alkaline character.
