, rather than sulfur radicals, accounts for the high solubilities of gold in magmatic-hydrothermal fluids. We also find that magmatic sulfur degassing is a redox process under oxidizing conditions and may lead to additional magma oxidation beyond that imparted by slab-derived fluxes and crystallization.
