Volcanic Arcs and Ores: Links of Magmatic Gases with Porphyry Copper and Epithermal Gold Deposits
occurs in different-sized bodies, associated with, and confined to, intrusive layered gabbroic masses (Fig.1). This study focuses on Abu Ghalaga ore, the main magmatic Fe-Ti deposit in Egypt. The ore reserves were estimated at 50 mt with an average grade ...
Minor- (Ti, Ni, V, Mn and Zn) and trace-element (Sc, Co and Ga) concentrations do not show any significant variations from Cr-spinel cores to boundaries and were not considerably modified by post-magmatic processes. However, Cr-spinel compositions show slight enrichments in Zn and V, ...
