The rare-metal granites of the Nubian Shield are commonly associated with Nb–Ta and Sn mineralization. magmatic hydrothermal evolution these their relation to mineralization need further investigations. This study reports new mineral chemistry, whole-rock geochemical, Sr–Nd isotopic data for Abu Dabbab in Central Eastern Desert Egypt provide insights into formation mechanisms consist mainly albite, orthoclase, quartz, Li-phengite, accessory minerals including cassiterite, columbite,...
Abstract Orogenic gold ores of the Arabian–Nubian Shield are structurally controlled by Najd Fault System. The System exhumation metamorphic complexes and, as such, there is a genetic relationship between metamorphism and formation orogenic ores. In order to constrain this relationship, field observations, petrography, geochemistry fluid inclusions four mines from Egyptian side shield presented. studied gold-bearing dykes veins where precipitated in pre-existing second-order third-order...
Abstract Gold‐silver deposits in the Atalla area occur as hydrothermal quartz veins NE–SW pre‐existing fractures within granitic pluton. The orientation of such has been attributed to extensional behavior related Shear Zone (ASZ). is covered by a variety lithologies that are (from oldest youngest): metasedimentary rocks, metavolcanic ophiolite assemblage (serpentinites/talc‐carbonates), granite and Dokhan volcanic rocks. Microscopically, ranges composition from granodiorite monzogranite....
The deals with the determination of possible radiological risks by help internationally approved health hazard addressed field and laboratory gamma measurements performed for surface, adit core samples from Gabal Abu Dabbab albite granite Ta-Nb-Sn mining area.The studied area is located some 50 km northwestern Marsa Alam city within central Nubian Shield Egypt.The were taken portable RS-230 γ-ray spectrometer spectrometric analyzes verified HPGe detector radioactivity 238 U, 226 Ra, 232 Th...
Mineralogical and Geochemical Studies on Manganese Deposits at Abu Ghusun Area, South Eastern Desert, Egypt I. A. Salem, N. H. El-Shibiny, M. Abdel Monsef Abstract The manganese deposit is subjected to mineralogical geochemical studies in order elucidate its petrogenesis. occurs as sheets, lenses, encrustation fracture filling within clastic sediments of the Formation Oligocene age. mineralogical, data confirmed by microscopic investigations, X-ray diffraction (XRD), infrared absorption...
Abstract The Haimur area represents the central part of Wadi Allaqi region in southern block Egyptian Eastern Desert near Nasser Lake and Nile valley. It is made up ophiolitic assemblage comprising serpentinite talc carbonate, listwenite, metagabbro/amphibolite metabasalt island arc assemblages. orogenic gold deposits occur form smoky/white sulphide-bearing quartz / quartz-carbonate veins or lenses cutting through listwenite zone-related rocks. NE-trending auriferous were formed due to an...
