Gabel El Ghurfa area is situated at the eastern part of Wadi Natash lies similar to 125 km ENE of Aswan and occupies some 130km2 of the exposed volcanics and Nubia sandstones. Gabel El Ghurfa forms a ring dyke (2km2) with a diameter of 1.2 km and composed mainly of normal and alkaline trachyte at the outer zone. The inner zone of the ring (600 m in diameter) is mainly represented by Lower Nubia sandstones (LNSS) and a minor trachyte plug. The LNSS is composed of conglomerate (at the base) followed by quartz arenite, greywacke and calcareous sandstone (at the top). The lower Nubia sandstones overlie the metasediments and overlain by the lower volcanic flows (alkali olivine basalt), whereas the Upper Nubia sandstones (UNSS) overlie the trachyte. The lower Nubia sandstones are characterized by uranium minerals (metaheinrichite, autunite and uranophane), sulfides and base metals (pyrite, galena, zincite, chromite, copper nickel, gold and silver) and accessories (e. g. zircon, monazite, spinel, sphene, fluorite, ilmenite, garnet, rutile and allanite) which confirmed by X-ray diffraction and ESEM analyses. The geochemical data of the bulk LNSS samples reflect the enrichment of SiO2, CaO, Zr, Ba, Sr, Ti, Cr and Ni. The LNSS deposited in semi-arid to semi-humid climatic conditions. Total rare earth elemental concentration of LNSS vary between 50 and 295 ppm. From the rare earth elements (REE) data, the LNSS are characterized by (1) enrichment in light rare earth element (LREE), (2) depletion in heavy rare earth element (HREE) relative to the light and (3) negative Eu-anomaly.
