Experiments of H2O solubility in synthetic haplogranitic and natural rhyolitic melts were conducted at 700–1200 8C and 0.098–25 MPa. Attainment of equilibrium was proven by reversals using starting materials with different initial H2O contents. Dissolved H2O contents were determined using Fourier transform infrared spectroscopy. When temperature decreases from 1000 to 700 8C, the solubility of H2O increases from 0.100 to 0.124 wt.% at 0.098 MPa, from 0.99 to 1.36 wt.% at 11 MPa, and from 1.46… CONTINUE READING
