IsochoreMicrothermometryPhase diagramsThe software AqSo_NaCl (Bakker, 2018) can be used to characterize the properties of phases that may exist in the binary H2O-NaCl system up to 1000掳C and 500MPa. The model replaces all available correlation equations and other equation of state that are ...
the isochore calculated from HOLLOWAY ( 198 1) lies below that of KERRICK and JACOBS (1981) for densities less than - 1.05 g/cm3 and then crosses over for higher densities. The pronounced curvature in SWANENBERG’S (1980) isochores is not seen in the rest of the calculations but ...
IsochorePVTx dataThis paper reports the application of thermodynamic models, including equations of state, to ternary CH4-H2O-NaCl fluid inclusions. A simple equation describing pressure-temperature-salinity relations on the CH4 hydrate-liquid-vapor surface has been developed to calculate the NaCl ...
Temperatures and pressures of metamorphism estimated from fluid inclusion microthermometry and isochore calculations are 450°–500° C and 700–1000 bars, respectively. A model is proposed in which the metamorphism at Patapedia was caused by heat transferred from a low to moderate salinity fluid of...
The total homogenization temperature, the CO2-clathrate melting temperature, and the homogenization temperature of the carbonic phase can be used precisely to calculate the pressure of total homogenization (on the solvus) and the corresponding isochore. The equation of state of Duan et al. (1995) ...
