The forsterite–kalsilite-SiO2–H2O plane lying in this system has significant bearing in the genesis of various potassium-rich igneous rock types. This plane has therefore, been the subject of numerous studies under variable P-T conditions in the presence or absence of a fluid component belonging to the C–H–O system (Luth 1967; Yoder and Kushiro 1969; Wendlandt and Eggler 1980a, b, c; Gupta and Green 1988; Seifert and Schreyer 1971; Foley et al. 1986).
