(a) Pyrite-bearing metarhyolite-ignimbrite sheets showing disseminated sulfides, (b) Stockwork made up of network of intersecting, thin (few centimeters thick), randomly oriented quartz veins, (c) Alteration zone at the northern bank of Wadi Ghorabi-El Hatemeia, (d) Quartz vein traverse the alteration zone and staining by green and blue copper carbonate, (e) Copper ore hosted mainly along fractures system related to shear zone traverse graywack and pyroclastic rocks at Wadi Khashm El-Fakha, (f) Gossan bodies mineralization along Wadi Tarr mineralization where copper carbonate form thin bands mixed with iron minerals and green staining. X-ray diffractograms of the studied ore mineralizations showing (g) a variety of primary minerals mainly pyrite, chalcopyrite, bornite, galena and sphalerite, (h) secondary minerals mainly malachite, azurite, chalcocite, cuprite, delafossitte, and tenorite.
