Abstract

Muscovite-bearing pelites near Rangeley, Maine. The proportion of muscovite-rich to biotite-rich pseudomorphs in the model is a function of the initial proportions of muscovite, plagioclase and staurolite, which govern the proportion of staurolite that is enclosed by sillimanite segregation mantles.--Modified journal abstract.
