Abstract

Distribution of Al-silicate minerals in pelitic schists indicates that the T and P of metamorphism were approximately those of the Al2SiO5 invariant point. This natural system is used to evaluate the internal consistency of several published geothermometers and geobarometers with the Al2SiO5 invariant point of Holdaway. (M.A. 74-3148)-J.A.Z.
