Experimental determination of CO₂-H₂O activity-composition relations at 600-1000 degrees C and 6-14 kbar by reversed decarbonation and dehydration reactions

Equation of state of the H2O, CO2, and H2O–CO2 systems up to 10 GPa and 2573.15K: Molecular dynamics simulations with ab initio potential surface

“…Fig. 10 shows the calculated activity-composition relations at 1073.15 K and two pressures of 0.6 and 1.4 GPa, they agree with those experimentally determined by Aranovich and Newton (1999).…”

Semi-empirical Gibbs free energy formulations for minerals and fluids for use in thermodynamic databases of petrological interest

“…Figure 16 shows the results of modelling the mixing properties of an H 2 O-CO 2 fluid with Eq. (27) Aranovich and Newton (1999) and Holland and Powell (2003) based on experimental data. This suggests that simple linear mixing rules can be used to extend our model on fluid mixtures without introducing any additional parameters.…”

The solubility of rocks in metamorphic fluids: A model for rock-dominated conditions to upper mantle pressure and temperature

“…H 2 O, CO 2 and CH 4 , are computed with an EoS from Connolly and Cesare (1993). Despite limitations of this molecular model in providing the exact speciation at elevated P (>2 GPa) and low T (<500 • C) where nonideality increases rapidly (e.g., Aranovich and Newton, 1999) and solutions are very dilute (Fig. 2), these were considered irrelevant for the present purpose of the study.…”
