Significant features of porphyry copper deposits were observed in the southern part of the Eastern Desert of Egypt. These include wide distribution of gossans cover and pyrite-rich zones, chalcopyrite disseminations, zoned hydrothermally altered mafic volcanics, hydrothermal breccia pipes, and quartz-vein sets in close association with granite porphyry intrusion. The investigated area is characterized...
The late Neoproterozoic of Wadi Ranga area, south Eastern Desert was characterized by extensive magmatism consisting predominantly of calc-alkaline older granitoids, Ranga volcanics and granite porphyry intrusions forming a belt of volcanic-intrusive complexes. Geological studies of the Ranga volcanics revealed two sequences of volcanic suites: the older mafic sequence composed essentially of basalt/basaltic...
