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

Petrographical and geochemical characters of the selected pebbles from some occurrence of the basal Hammamat conglomerates, Central Eastern Desert, Egypt.

2018-09-04 10:32:11 Keywords Hammamat sediments, Geochemistry, Eastern Desert, Egypt, Um Gheig, Abu Shiqieli, Hammamat sediments, Geochemistry, Eastern Desert, Egypt, Um Gheig, Abu Shiqieli, Dokhan volcanics,
Petrographical and geochemical characters of the selected pebbles from some occurrence of the basal Hammamat conglomerates, Central Eastern Desert, Egypt.
The Hammamat Group includes a thick succession of unmetamorphosed clastic sediemnts in the eastern desert of Egypt. The unconformity relationship with the underlying Dokhan volcanics and older rocks is recorded in several occurrences. However, it is established that the Hammamat sediments and DOkhan volcanics were formed penecontemporaneously. The present study deals with detail study of two occurrences of basal conglomerates, ...

Petrographical, geochemical and metamorphic aspects of allochthonous Hammamat sediments at Wadi Mubarak, Central Eastern Desert, Egypt.

Petrographical, geochemical and metamorphic aspects of allochthonous Hammamat sediments at Wadi Mubarak, Central Eastern Desert, Egypt.
The old hammamat sediments along Wadi Mubarak (previously mapped as metasedimentary Beririq Formation) form an allochthonous unit trending NE-SW, sandwiched between island arc assemblage (lower unit) to the north and ophiolitic melange (upper unit) to the south. These old Hammamat epiclastic sediments are composed essentially of alternating coarse polymictic conglomerates, fine polymictic conglomerates, siltstones, arenites, grewackes intercalated with calcareous pelites. ...
