Structural and tectonic evolution of the Umm Gheig/ El-Shush region, central Eastern Desert of Egypt
The rocks of the Wadi Umm Gheig/El-Shush area in the central Eastern Desert of Egypt form part of the Nubian Shield, a component of the Neoproterozoic Pan-African Orogeny. The rocks have been divided into three units: (i) low-grade metamorphosed rocks, which consist of metavolcanic rocks interleaved with slices of ophiolitic melange; (ii) high-grade metamorphic rocks, which consist of syn-tecto...
متن کاملGeochemical Characteristics and Chemical Electron Microprobe U-Pb-Th Dating of Pitchblende Mineralization from Gabal Gattar Younger Granite, North Eastern Desert, Egypt
Pitchblende mineralization was studied in the younger granite samples collected from Gabal Gattar, north Eastern Desert, Egypt using electron scanning microscope (ESM) and electron probe microanalyses (EPMA). This study revealed that this pitchblende contains significant Zr content reaching up to (66.80% ZrO2), which suggests that volcanic rocks were probably the source of such a deposit. High ...
متن کاملEocene Stratigraphy, Facies, Sequenses and Depositional History in Shabraweet Area, North of Suez, Eastern Desert, Egypt
The Eocene rocks in Shabraweet area comprise the Lower, Middle and Upper Eocene stages. Each stage consists of only one rock unit; the Minia Formation, the Mokattam Formation and the Maadi Formation, respectively. The Minia Formation shows angular unconformity relationship with the underlying Cretaceous rocks and disconformity relationship with the overlying Mokattam Formation. The Maadi Format...
متن کاملPan-African granite emplacement mechanisms in the Eastern Desert, Egypt
The late Pan-African Fawakhir, Urn Had and Urn Effein Granite Plutons in the Egyptian Central Eastern Desert are small, elongate to circular bodies of pink monzogranite and syenogranite, and grey monzodiorite. Structural investigation of the intrusive contacts of these plutons reveals marginal sub-horizontal intrusive sheets as magma injection along preexisting flat-lying structures including m...
متن کاملemplacement of granites in a transitional regime from volcanic arcs to post-collisional: an evidence from the gabal el-zeit block, gulf of suez region, egypt
gabal el-zeit block at the western coast of the gulf of suez region in egypt consists of two varieties of precambrian granites, namely monzogranite and a peripheral zone of alkali granite. both granitic varieties display moderate (60.1-68.5 wt%) and high silica (73.36-76.16 wt%) contents with high na2o+k2o (7.21-8.61 wt%), respectively. the investigated monzogranite is calc-alkaline metaluminou...
