Geochemistry, petrogenesis and radioactivity of Pan-African granitoids, Fatirah area, Eastern Desert, Egypt.
On the basis of the geological and petrological investigations, the Pan-African granitoid rocks of Wadi Fatirah area are differentiated into two distinct assemblages, viz. the older granites and younger granites. The older granitoids comprise quartz diorite, tonalite and granodiorite, arranged in accordance to their sequence of emplacement. The older granites are calc-alkaline in character and of I-type and were emplaced ... Read more

Structural elements and metamorphism controlling the late Pan-African Hammamat sediments at the Up-stream of Wadi El-Miyah, Central Eastern Desert, Egypt.

Structural elements and metamorphism controlling the late Pan-African Hammamat sediments at the Up-stream of Wadi El-Miyah, Central Eastern Desert, Egypt.
The Hammamat sediments at the Upper stream of Wadi El Miyah, Central Eastern desert of Egypt, occupy two isolated basins separated from each other by metavolcanics associated with their equivalent volcanoclastics and intruded by the younger granites. In the Eastern basin, the Hammamat succession rests unconformably over the metavolcanics, with basal conglomerates up to 5 m thick, and four distinct ... Read more
