摘要

The Na/K ratio in geothermal well waters provides a better estimate of the relative stability of low albite and potash feldspar than do predictions from calorimetry and high temperature phase equilibria. The calculated saturation indices from field data for low albite, potash feldspar suggest that (Delta)G(sub f,298)(sup o) for the latter should be revised to (minus)3748.6(plus minus)3.7 kJ.mol(sup (minus)1).
