| Although fluids and melts are phases of central importance to many branches of geology, there is very little relevant data on their thermodynamic properties compared to crystalline phases. A new technique for experimentally determining activity coefficients for H;This data can then be used in conjunction with the integration of the multicomponent Gibbs-Duhem relation to calculate thermodynamic properties the silicate melt components. In order to integrate the Gibbs-Duhem equation across the melt + vapor miscibility gap in the system sanidine-albite-H... |
