SOLVCALC: an interactive graphics program package for calculating the ternary feldspar solvus and for two-feldspar geothermometry

摘要: Abstract The program SOLVCALC is a user-friendly graphic interface software for calculating the ternary feldspar solvus and equilibrium temperature of coexisting natural pairs. Twelve isotherms (with or without tielines) twelve thermometric tielines can be plotted on each screen. zoom move functions greatly reduce any physical limitations screen itself. Six different thermodynamic models one user-defined model are incorporated into this both calculations thermometry. An activity matching algorithm used calculations. For geothermometric calculations, an to search most concordant by adjusting compositions within selected uncertainty. as research teaching tool comparing well development new models. runs PC-compatible computers with DOS 3.1 later version VGA card.
