Origin and geochemistry of Egyptian granitoid rocks in Nuweiba area, eastern Sinai

Metamorphic evolution of Neoproterozoic metapelites and gneisses in the Sinai, Egypt: Insights from petrology, mineral chemistry and K–Ar age dating

“…The Sharira diorite is an undeformed hornblende diorite and was dated at 570 ± 4 Ma (Moghazi et al, 1998). Except for the Tarr Formation, all the KMC formations are intruded by undeformed to slightly deformed biotite bearing alkaline granites (Brooijmans et al, 2003), which were interpreted geochemically as A-type granites by Ahmed et al (1993). Similar granites in the Timna area are interpreted to have been formed in an extensional regime (Beyth et al, 1994).…”

“…The Quneia Formation consists of foliated and lineated diorites and tonalities and is plutonic in origin. Similar intrusives in the nearby Nuweiba area were interpreted as subduction-related I-type intrusives (Ahmed et al, 1993). The Sharira diorite is an undeformed hornblende diorite and was dated at 570 ± 4 Ma (Moghazi et al, 1998).…”

Lu–Hf and O isotopic compositions on single zircons from the North Eastern Desert of Egypt, Arabian–Nubian Shield: Implications for crustal evolution

“…Characteristic macroscopic features in the older granitoids include whitish gray color, commonly transected by granitic pegmatites (instead of quartz veins), well-developed mineral foliation, and complex contact relations, e.g., migmatization (Greenberg, 1981;El-Gaby et al, 1988;El-Mettwaly, 1992;Ahmed et al, 1993;El-Sheshtawi et al, 1995;Furnes et al, 1996;Moghazi, 1999;AbdelRahman and El-Kibbi, 2001;Moghazi, 2002).…”

Petrologic and geochemical characterization and mineralization of the metavolcanic rocks of the Heib Formation, Kid Metamorphic Complex, Sinai, Egypt

“…The Quneia Formation consists of foliated and lineated diorites and tonalites with occasional mafic xenoliths and/or microgranular enclaves. Comparable subduction-related I-type diorites (Furnes et al, 1985;Ahmed et al, 1993) in the Nuweiba area, about 100 km north of the KMC, gave an RbeSr whole-rock age of 581 AE 11 Ma (Moghazi et al, 1998). The Shahira gabbro-diorite occurs as a single large intrusive body in the northern part of the KMC.…”
