The chemistry of hydrothermal tin(-tungsten) ore deposition

A qualitative model for the formation of granite-related mesothermal cassiterite(-wolframite) deposits is derived from a review of geologic evidence and is then tested quantitatively with chemical mass transfer calculations based on published experimental and thermodynamic data.Laboratory experiments and geologic, mineralogic, fluid inclusion, and stable isotope observations indicate that saline fluids of magmatic origin are involved in the...
