Fig. 31From: Fluids and physicochemical properties and processes in the EarthExperimentally determined activity-composition relations along the H2O–CO2 join at 800 °C and 1.4 GPa. Data points are from experimental results by Aranovich and Newton (1999) and calculated curves from Duan and Zhang (2006). Curves denoted γCO2 = 1 and γH2O = 1 indicate lines of ideal mixingBack to article page
