The tectonic regioning of the basement rocks of the Eastern Desert of Egypt
The basement rocks of the Eastern Desert of Egypt represent a Proterozoic eugeosynclinal system. This system is the northern part of a vast geosynclinal belt which extends southwards into the Ethiopean plateau. It is divided into three major geosynclinal zones, namely: a) Wadi AllaqiWadi Kharit zone...

Tartalmi kivonat: | The basement rocks of the Eastern Desert of Egypt represent a Proterozoic eugeosynclinal system. This system is the northern part of a vast geosynclinal belt which extends southwards into the Ethiopean plateau. It is divided into three major geosynclinal zones, namely: a) Wadi AllaqiWadi Kharit zone, with Gebel Holwa-Gebel Seiga-Gebel Nigrub, and Gebel Migif — Gebel Hafafit median masses in its southern and northern parts, respectively, b) Wadi El Miyah — Wadi Atalla geosynclinal zone, which includes Gebel Meatiq median mass, and c) Wadi Belih — Wadi Hawashiya geosynclinal zone. These zones are generally bordered by deep-seated faults, and are separated from each other by Gebel Abu Diab and Gebel El Shayeb geoanticlinal zones. The median masses are probably Archean-Lower Proterozoic, and might have existed prior to the Proterozoic eugeosynclinal system. This tectonic regioning is based on the results of the regional geological mapping programs, field observations of the authors, the distribution and lithology of the different rock formations and their structural relations, as well as the geomorphological features of the area under consideration. |
