Fig. 8From: Rheology and stress in subduction zones around the aseismic/seismic transitionStructural and microstructural characteristics of the South Fork Mountain Schist. a The dominant foliation in pelitic schist is a transposed crenulation cleavage, formed by microfolding an earlier differentiated fabric, accompanied by pressure solution. b Mesoscopic folds deforming a differentiated fabric, with a new crenulation cleavage forming parallel to the axial planes. c, d Photomicrograph showing the dilational arcs and pressure-solution seams that form in conjunction with the dominant crenulation cleavageBack to article page
