In a geological context, crenulation or crenulation cleavage is a fabric formed in metamorphic rocks such as phyllite, schist and some gneiss by two or more stress directions causing the formation of the superimposed foliations. == Formation == Crenulations form when an early planar fabric is overprinted by a later planar fabric.
