Metapelites are metamorphosed clay-rich sedimentary rocks. Different pelitic index minerals form at different grades of metamorphism. Isograds, based on index minerals, are lines on maps that separate zones of different metamorphic grades. Different characteristic minerals develop in metapelites that form at high, medium, and low pressure.
