Figure 5. Garnet compositions in calc-silicate rocks for almandine (Alm), pyrope (Prp), grossular (Grs), spessartine (Sps), and andradite (Adr) components (mineral abbreviations after Kretz, 1983). Solid circles represent garnet grains in equilibrium with clinopyroxene in Zone VI; open circles represent garnet grains from Zones II, III and IV; triangles represent garnet grains partially transformed to plagioclase, calcite, and quartz.
