Nickel-copper sulfide ores with PGEs result from settling and accumulation of immiscible sulfide liquids in mafic layered intrusions and ultramafic magma conduits. In layered intrusions, Fe-Ti oxides, chromite and PGE minerals crystalize from evolving parental magmas and are con-centrated by physical processes in cumulate layers.
