摘要: The rate of oxygen isotope exchange between adularia and 2 M KCl solution has been measured at 650°C pressures from 125 to 4000 bar. Isotropie diffusion coefficients calculated these data show a positive dependence on the fluid pressure. This is opposite predicted effect hydrostatic pressure attributed activity ‘water’ (H2O, H+ or OH−) in feldspar.
