Mineralogy, Types and Genesis of the Copper-Gold-SulphideOre Mineralization, of Um ZerriqArea, Metallogenic KidBelt in Southeastern Sinai, Egypt
Journal Title: Caspian Journal of Applied Sciences Research - Year 2012, Vol 1, Issue 10
Abstract
The copper-gold-sulphide mineralization in the Um Zerriq area forms part of the metallogenic Kid belt of southeastern Sinai, Egypt. Mineralization is the result of three sequential main types consisting of porphyry, epithermal, and Skarn mineralization. Sulfide assemblages and their textures were useful to identify each type and their paragenesis. The porphyry Copper-gold mineralization shows mineral assemblages started by sulfide-oxide mineral assemblages that are represented by pyrite, magnetite, and chalcopyrite. Followed by Au-bearing assemblages which include chalcopyrite, bornite, molybdenite, pyrite, magnetite, hematite, minor base metal sulfides and rare sulfosalts. The deep-seated porphyry Copper-gold deposit has close spatial association with the epithermal Copper-gold deposits. The epithermal mineralization of the Um Zerriq has dominant (1) Galena-sphalerite-chalcopyrite ± gold, (2) Quartz-pyrite, (3) Chalcopyrite-covellite-bornite, (4) Galena-sphalerite-chalcopyrite assemblages. In the skarn mineralization the Cu-bearing mineral is chalcopyrite accompanied by bornite, magnetite and hematite at the deeper horizons. In the skarn polimetallic deposit sphalerite is essential, associated by galena and magnetite. Skarn Cu-Zn-Pb mineralization was formed in older orogenic belts where skarn is associated with both plutonism and high T-P metamorphism: Identified minerals assemblage includes Sphalerite-arsenopyrite-lollingite-pyrite-galena assemblage and massive galena assemblage.
