摘要

In the study of hydrothermal deposits sulfur isotopes bear much information about the source of sulfur, ore-forming temperature, the evolution of ore-forming fluids and the mechanism of metallogenesis. To determine whether sulfur isotopes reach equilibrium between fluids and sulfur-bearing minerals precipitated from the former and among the sulfur-bearing minerals is the key to the application of sulfur isotope geochemistry to geological problems. As it has been commonly accepted that sulfur isotopic equilibrium could not be reached between sulfate and sulfide below 350 deg, little attention has been paid to the possible mechanism of sulfur isotope equilibrium between sulfate and sulfide below 300 deg.
