Hydrothermal reactions involving equilibrium between minerals and mixed volatiles

摘要: Abstract The properties of fluids in the CO 2 CH 4 H O system including and CH binary ternary mixtures with total gas compositions varying from 5.5 to 16.5 mole% were studied at temperatures between 400° 600°C pressures 1000 3000 bar. Gas-loading techniques described Part 1 combined synthetic fluid inclusion methods utilized produce inclusions known composition. Densities, isochores, liquid-vapor curves clathrate melting relations determined for using measurements temperature solid carbon dioxide, homogenization bubble. found be excellent agreement previously published results H.

Isochores resulting this study vary significantly theoretical calculations particularly case low concentrations binary.
