Similar foliation patterns are observed in faults in poorly lithified sediments, fault gouge and cataclasite, and greenschist to granulite facies shear zones. We suggest that this similarity in form reflects similar controls on development. We propose that these patterns are a fundamental consequence of deformation of heterogeneous media, in which material heterogeneity is manifest as competency contrast. Strain incompatibilities along competence domain boundaries can produce mechanical… CONTINUE READING
