摘要: Abstract This paper presents a general method for the calculation of mineral-melt phase equilibria based on mass balance, stoichiometry, and single component distribution coefficients. An algorithm practical application this is developed, computer program using stability, proportions, composition has been included. The includes both equilibrium fractional models melting crystallization. particular implementation incorporates specific coefficient model olivine, plagioclase, clinopyroxene crystallization in basaltic systems. Calculated results from agree with those experiments terrestrial compositions. designed to be modified easily incorporate other detailed data sets. In way, should able applied diverse compositions, assemblages, physical processes crystal/liquid interaction. general, its provide calculating multicomponent,
