Crenulations and metamorphic differentiation. Foliations are among the most prominent features of deformed metamorphic rocks. They form by the progressive re-orientation of platy grains into parallelism. Crenulations are small folds, typically axial planar to larger-scale folds, that deform earlier foliations.
