Empirical expressions of quartz solubility in H2O, H2O+CO2, and H2O+NaCl fluids.

Rutile solubility in supercritical NaAlSi3O8–H2O fluids

Rutile solubility in H2O, H2O–SiO2, and H2O–NaAlSi3O8 fluids at 0.7–2.0 GPa and 700–1000 °C: Implications for mobility of nominally insoluble elements

Quartz solubility in H2O-NaCl and H2O-CO2 solutions at deep crust-upper mantle pressures and temperatures: 2–15 kbar and 500–900°C

The solubility of quartz in H2O-NaCl solutions was measured at 2, 4.35, 10 and 15 kbar and 500–900°C, and at NaCl concentrations up to halite saturation, usually greater than 75 wt.%. Quartz solubility was also measured in CO2-H2O solutions at 10 kbar and 800°C. Solubilities were determined by weight loss of ground and polished quartz crystal fragments which were equilibrated with solutions in ...

The solubility of fluorite in H2O and H2O–NaCl at high pressure and temperature

The solubility of fluorite in H2O and H2O–NaCl has been measured at 600–1000 °C, 0.5–2.0 GPa in a piston–cylinder apparatus. Fluorite dissolves congruently at all conditions investigated. The data indicate that the concentration of fluorite dissolved in H2O is low at 600 °C and 0.5 GPa (0.0014 mol/kg H2O) but increases strongly with temperature (T) and pressure (P) to 0.247 mol/kg H2O at 1000 °...
