The present work deals with the ferrugination of Agib Ring Complex hosted by granites, Southeastern Desert Egypt. The studied Agib Ring Complex comprises well developed outer ring of alkali rhyolite porphyry and a quartz syenite core. Trachytes and their pyroclastic equivalents, forming roof pendants and rafts, represent the remnants of volcanic cone. The rock units of Agib ring complex are peralkaline formed in within plate tectonic setting. The quartz syenite consists essentially of perthitic orthoclase, antiperthitic plagioclase and quartz with relatively minor alkaline ferromagnesian minerals. The trachyandesites are generally porphyritic almost holocrystalline and occasionally hyalopilitic with phenocrysts of plagioclase, hornblende, chlorite, epidote, and quartz. The rhyolites are porphyritic holocrystalline to hypocrystalline with aphanitic matrix. The pyroclastics are very fine-grained groundmass, enclosing subangular to subrounded lithic clasts within the lapilli size. The host alkali feldspar granite is composed of antiperthitic plagioclase, perthitic orthoclase, hornblende, arfvedsonite, aegirine and quartz. Intense ferrugination is recorded in the rock units of Agib ring complex and the host rocks in the form of disseminated crystals or skeleton like crystals, filling the fractures, replacing the rock forming minerals and staining. The recorded ore minerals are hematite, magnetite martite, goethite and ilmenite forming the hydrothermal iron mineralization.
