Geochemical constraints on the tectonomagmatic evolution of the late Precambrian Fawakhir ophiolite, Central Eastern Desert, Egypt
Abstract The Fawakhir ophiolitic sequence is composed mainly of serpentinites, metagabbros, boninitic metagabbros and metavolcanics. The serpentinites have geochemical features similar to those ofExpand

Geochemistry and Petrogenesis of the Neoproterozoic Granitoids in the Central Eastern Desert, Egypt
Abstract Neoproterozoic rocks in the Umm Gheig Province (UGP), central Eastern Desert, comprise five plutonic rock suites, i.e. a gabbro-diorite suite (GDS), an older granitoid suite (OGS), an I-typeExpand

Garnet-bearing leucogranite in the El-Hudi area, southern Egypt: evidence of crustal anatexis during Pan-African low pressure regional metamorphism
Abstract The Wadi El-Hudi area, in the south Eastern Desert of Egypt, comprises a high-grade metamorphic complex of migmatite and biotite gneiss that host a garnet-bearing leucogranite body. ThisExpand

Geochemistry and petrogenesis of Sikait leucogranite, Egypt: an example of S-type granite in a metapelitic sequence
Abstract The Sikait leucogranite (SLG) is a body of porphyritic garnet granite intruded a metapelitic sequence and interlayered orthogneisses. Multiple deformation and low- to medium-gradeExpand
