Mineralogical and Geochemichal aspects of Nb-Ta oxide minerals from Wadi El Sheih mineralized pegmatite, Central Eastern Desert, Egypt

Rare-metals and rare earth mineralization has been observed in Wadi El Sheih older granitoids bearing uncommon mineralized pegmatite. This type of was recorded as distinguishable mega-crystals scattered within the Detailed mineralogical investigation carried out using different analytical techniques as: microscopic examinations, x-ray diffraction (XRD), scanning electron microscope (SEM) providing with energy dispersive spectrometer (EDS) unite. These studies revealed presence several valuable minerals like Euxenite Fergusonite well as; gives a clear comparative idea on geochemical characteristics Nb-Ta oxides.
