WebbMetamorphic rocks are often intimately related to large-scale (kilometres of tens of kilometres) structural features of Earth. Such features include folds, nappes, and faults … WebbThis typically follows the same principle as mica growth, perpendicular to the principal stress. Metamorphic differentiation can be present at angles to protolith compositional banding. Crenulation cleavage and oblique foliation are particular types of foliation. Interpretation [ edit]
