The IAPWS-95 formulation explicit in Helmholtz free energy proposed by Wagner and Prub (2002) is the best equation of state of water, from which all thermodynamic properties can be obtained over a wide Tep range from 273.16 to 1273 K and from 0 to 1000 MPa with experimental accuracy. This paper reports the applications of the IAPWS-95 formulation in fluid inclusion and mineral-water phase equilibria. A reliable and highly efficient calculationmethod is presented for the saturated properties of water so that the formulation can be conveniently applied in the study of fluid inclusion, such as calculating homogenization pressures, homogenization densities (or molar volumes), volume fractions and isochores. Meanwhile, the univariant curves of somemineral-dehydration reactions are calculated based on the IAPWS-95 formulation. The computer code of the IAPWS-95 formulation can be obtained from the corresponding author.
