Abstract
In-situ hydrothermal experiments using diamond-anvil cell show that sulfate and sulfide are the dominant sulfur species under P-T conditions similar to those of porphyry magmas. No sulfite was identified using in-situ Raman spectrometer. This supports that porphyry copper mineralization is controlled by sulfate reduction, rather than sulfite disproportionation.
