主　　题：diamond cell sulfate sulfi de porphyry deposits magnetite crisis 

摘      要：In-situ hydrothermal experiments using diamond-anvil cell show that sulfate and sulfi de are the dominant sulfur species under P-T conditions similar to those of porphyry magmas.No sulfi te was identifi ed using in-situ Raman spectrometer.This supports that porphyry copper mineralization is controlled by sulfate reduction,rather than sulfi te disproportionation.
