Sulfur isotope geothermometry uses the temperature-dependent fractionation of 34S/32S between co-existing sulfide minerals in isotopic equilibrium; this fractionation factor is primarily controlled by temperature, with pressure having a negligible direct effect on stable isotope fractionation.
Statement A is correct: the 34S/32S ratio in co-existing sulfide minerals that reached isotopic equilibrium with a common sulfide reservoir is indeed temperature-dependent and can...
