The eugeosynclinal filling (Abu Ziran Group) in the area SW of port Safaga, eastern desert

The significance of gneissic rocks and synmagmatic extensional ductile shear zones of the Barud area for the tectonics of the North Eastern Desert, Egypt

“…Graded bedding in the sandier metasediments indicates consistent upward younging for the sequence. The characteristic ''cross-bedding'' reported by El-Gaby and Habib (1980) is probably of tectonic origin representing cleavage oblique to bedding (Fig. 3a).…”

“…This unit was identified by Akaad et al (1973) as a coarse homogenized hornblende gneiss, and was later named the Abu Maya diorite gneiss by El-Gaby and Habib (1980Habib ( , 1982. It forms a northeast-trending mass within the Barud Tonalite (Fig.…”

“…Fundamental ideas on the relations between gneissic granitoids and supposed older pre-PanAfrican continental crust were partly based on a study of this area by Akaad et al (1973). Detailed regional studies have also been completed by El-Gaby and Habib (1980Habib ( , 1982 and Habib (1987a,b). Mainly geochemical studies of the granitoids in the Barud area have been reported by Ghobrial and Girgis (1982), Dardier and Al-Wakeel (1998), El-Shazley and El-Sayed (2000) and Kamal ElDin (2003).…”

“…Alternatively, these amphibolites and schists have been labeled as the Abu Furad Gneiss, grouped together with granitoid gneissic rocks, and considered as part of the pre-Pan-African continental crust (Barud infrastructure) by El-Gaby and Habib (1980Habib ( , 1982; Habib (1987a,b); El-Gaby et al (1988);El-Gaby (1994) and El-Shazley and El-Sayed (2000). A part of these amphibolites was identified as Meatiq Group by Masoud et al (1992).…”

“…We follow closely the stratigraphic nomenclature for the map units in the Barud area suggested by El-Gaby and Habib (1980Habib ( , 1982, modified by Habib (1987a,b). However, we do not subscribe to the relative ages given to these units by Habib (1980, 1982) since the boundaries between them are mainly faults and shear zones (Fig.…”
