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 ...
متن کاملSolubility of Anhydrite, CaSO4, in NaCl–H2O Solutions at High Pressures and Temperatures: Applications to Fluid–Rock Interaction
Anhydrite solubility in H2O–NaCl solutions was measured at 6–14 kbar, 600–800 C and NaCl mole fractions (XNaCl) of 0–0 3 in piston–cylinder apparatus. Solubilities were determined by weight changes of natural anhydrite in perforated Pt envelopes confined with fluid in larger Pt capsules. In initially pure H2O at 10 kbar and 800 C, CaSO4 concentration is low (0 03molal), though much larger than ...
متن کاملThe 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 °...
متن کاملSolubility of grossular, Ca3Al2Si3O12, in H2O–NaCl solutions at 800 C and 10 kbar, and the stability of garnet in the system CaSiO3–Al2O3–H2O–NaCl
The solubility and stability of synthetic grossular were determined at 800 C and 10 kbar in NaCl–H2O solutions over a large range of salinity. The measurements were made by evaluating the weight losses of grossular, corundum, and wollastonite crystals equilibrated with fluid for up to one week in Pt capsules and a piston-cylinder apparatus. Grossular dissolves congruently over the entire salini...
