Chemical layering in metamorphic rocks is a good example of self-organization in geology. Local equilibrium between a mineral and an intergranular fluid generates a coupling of diffusion flows which can cause diffusion up the concentration gradient. Resultant oscillatory concentration profile will produce chemical layering, when associated with dissolution-precipitation reactions.
