Large, layered intrusions throughout the world are characterized by a remarkable paucity in economically important magmatic Ni–Cu sulfide deposits. The Sudbury intrusion in Canada is a notable exception, but sulfide ores there were formed by a unique combination of processes involving crustal meltin...
