Petrological and mineralogical studies of Pan-African serpentinites at Bir Al-Edeid area, central Eastern Desert, Egypt
The studied serpentinites occur as isolated masses, imbricate slices of variable thicknesses and as small blocks or lenses incorporated in the sedimentary matrix of the mélange. They are thrusted over the associated island arc calc-alkaline metavolcanics and replaced by talccarbonates along shear zones. Lack of thermal effect of the serpentinites upon the enveloping country rocks, as well as th...
متن کاملEocene Stratigraphy, Facies, Sequenses and Depositional History in Shabraweet Area, North of Suez, Eastern Desert, Egypt
The Eocene rocks in Shabraweet area comprise the Lower, Middle and Upper Eocene stages. Each stage consists of only one rock unit; the Minia Formation, the Mokattam Formation and the Maadi Formation, respectively. The Minia Formation shows angular unconformity relationship with the underlying Cretaceous rocks and disconformity relationship with the overlying Mokattam Formation. The Maadi Format...
متن کاملStructural and tectonic evolution of the Umm Gheig/ El-Shush region, central Eastern Desert of Egypt
The rocks of the Wadi Umm Gheig/El-Shush area in the central Eastern Desert of Egypt form part of the Nubian Shield, a component of the Neoproterozoic Pan-African Orogeny. The rocks have been divided into three units: (i) low-grade metamorphosed rocks, which consist of metavolcanic rocks interleaved with slices of ophiolitic melange; (ii) high-grade metamorphic rocks, which consist of syn-tecto...
متن کاملMineral Exploration and Alteration Zone Mapping in Eastern Desert of Egypt Using Aster Data
This paper proposes a method to find gold deposits in the Eastern Desert of Egypt. Different methods including various classification methods, principle component transform (PCT), band ratios, and a constrained energy minimization technique are evaluated for their performance for hydrothermal alteration zone mapping. First, these techniques are carried out to highlight known gold deposits over ...
متن کاملGeochemical constraints on the tectonomagmatic evolution of the late Precambrian Fawakhir ophiolite, Central Eastern Desert, Egypt
-The Fawakhir ophiolitic sequence is composed mainly of serpentinites, metagabbros, boninitic metagabbros and metavolcanics. The serpentinites have geochemical features similar to those of depleted-mantle peridotites. Major and trace element characteristics show that the ophiolitic metagabbro and metavolcanic rocks are of tholeiitic to calc-alkaline affinity. REE abundances in the metagabbros a...
