Sulphur Solubility in Felsic Magmas: Implications for Genesis of Intrusion-related Gold Mineralization

Sulphur solubility and the state of sulphide/sulphate saturation in felsic magmas play an important role in the formation of intrusion-related gold systems. The solubility of sulphur in felsic magmas is mainly controlled by temperature, pressure, redox condition(s), melt composition, and sulphur diffusion, although the sulphur source is considered an essential factor controlling the ultimate sulphide content in the melt. Decreasing temperature...
