... and subsequent reworking of sulfide. The Munali Ni deposit is hosted by a dynamic intrusive mafic-ultramafic system situated within the Zambezi belt in southern Zambia. The deposit comprises Fe-Ni–dominant magmatic sulfides, present as a number of lenticular massive sulfide bodies that display a variety...

Loop textures in massive and semimassive ores hosted in mafic or mafic-ultramafic intrusions. A) Sulfide vein fill and B) sulfide matrix breccia from the Munali deposit, Zambia. C) Massive sulfide from the Ovoid, Voisey’s Bay (photo credit Steve Beresford). D) Sulfide matrix breccia from the Akelikongo deposit, Uganda. Note presence of pentlandite as loops surrounding pyrrhotite grains in all images. All images are false color maps except C, reflected light on uncut drill core.

Sulfide emplacement model. A) Rifting of Irumide-aged granite basement. B) Deposition of Zambezi supracrustal sediments during extensional rifting. C) Normal faulting and extension during continued rifting. D) Emplacement of mantle-derived mafic-ultramafic melts along translithospheric structures utilizing carbonate-rich lithologies. E) Sulfide saturation generating sulfide liquid droplets settling to form sulfide pools generating density-driven sulfide slurries; inset highlighting fractionation of sulfide within the Munali Intrusive Complex (MIC), with monosulfide solid solution (mss) crystallization and further migration of a Cu-rich residual sulfide liquid. F) Regional compression during Pan-African orogeny causing folding and tilting of Zambezi sedimentary sequence. G) Reactivation of normal faults to high-angle reverse faults causing major displacement. H) Erosion resulting in current morphology of Munali Intrusive Complex highlighting potential levels of segregated Cu-rich and Cu-poor orebodies.
