Abstract

The basal spacings of muscovite in schists over a wide area of regional metamorphism in northwestern Maine reflect the metamorphic grade as determined by the mineral assemblages. The data indicate that the muscovites are more K rich above the K feldspar-sillimanite isograd than below it. Anomalous data can be correlated with incomplete or local equilibrium in the rocks. It is proposed that the basal spacings be used to monitor metamorphic conditions and to decipher the relative importance of different physico-chemical variables.
