AB The Ossa Morena Zone (SW Iberia) hosts an unusual suite of ore deposits, includingmagmatic Ni-(Cu) and IOCG mineralization. These deposits are interpreted to have a relationship toa deep mafic sill intruded in the middle crust. Interaction of mafic magmas with crustal rocks producedimmiscible sulphide-rich melts and water-rich melts. The latter exsolved large amounts ofFe- and CO2-rich brines that were responsible for widespread albite-actinolite alteration and IOCGmineralization.
