AbstractThe prevailing view of the formation of porphyry copper deposits along convergent plate boundaries involves deep crustal differentiation of metal-bearing juvenile magmas derived from the mantle wedge above a subduction zone. However, many major porphyry districts formed during periods of flat-slab subduction when the mantle wedge would have been reduced or absent, leaving the source of the ore-forming magmas unclear.

Copper is one of the most conductive metals known to humankind, making it the cornerstone for all electricity related technologies (e.g., cars, power generation, household appliances). This is causing an ever-increasing global demand for copper to support society's efforts for a low-carbon future. Most of the world's copper is derived from porphyry copper deposits (PCDs), where magmatic-hydrothermal fluids cause copper-ore mineralization centered on a granitic intrusion.
