Figure 4. Garnet compositions in metapelitic rocks are plotted as a function of almandine (Alm), grossular (Grs), and pyrope (Pyr) end-members. Projection is from spessartine. Light gray arrows indicate core-to-rim variations. Arrow length is proportional to the amount of compositional variation between cores and rims. Mineral abbreviations after Kretz (1983). HGS = high-grade schist.
