Mantle Oxidation by Sulfur Drives the Formation of Giant Gold Deposits in Subduction Zones Academic Background Most of Earth’s metal resources are concentrated in magmatic arc environments, and subduction zones are the primary regions for mass exchange between the mantle and crust. Fluids released from subducting slabs are believed to oxidize the o...
