The compositional evolution of melilite in the local modifications followed the curves b then c, producing monticellite, spurrite or tilleyite and granditic garnet, until the H2O pressure was high enough for vesuvianite to become stable. In the sample OC44, which originally contained wollastonite, the evolution took place at higher activity of silica, which resulted in the absence of spurrite or tilleyite and the appearance of vesuvianite together with gehlenite more Al-rich (Gh90) than in other samples.]()
