Abstract
H2O solubility has been determined in haplogranitic melts in the range 0.5-8 kbar and 800-1350°C. Seventeen compositions containing 25, 35, or 45 wt% normative Qz and with various Or/(Or + Ab) ratios were investigated. At 0.5 kbar, H2O solubility was little affected by the anhydrous composition. By contrast, molar H2O solubility in aluminosilicate melts was significantly dependent upon anhydrous composition between 1 and 5 kbar. The effect of pressure on H2O solubility at P ≥ 3 kbar is greater than that reported in previous studies. The effect of temperature on H2O solubility was investigated for a composition Qz28Ab38Or34 in the P-T range 0.5-8 kbar and 800-1350°C. Water solubility ranged from retrograde (with increasing T) at P ≤ 4 kbar through temperature independence at approximately 4.5 kbar to prograde at P = 5 kbar. -from Authors
