Fig. 6From: Microtextural investigation (SEM and TEM study) of phyllosilicates in a major thrust fault zone (Monte Perdido, southern Pyrenees): impact on fault reactivationBackscattered scanning electron images on ion-milled sample from the highly deformed clay-rich sediment from fault zone. a General view of the sample. The black area corresponds to the hole created by the ion-milling. Chlorite and calcite shear veins are clearly distinguished from the grey matrix. b, c Views at higher magnification of the shear vein and cleavage relationship. The arrows indicate the sense of shearBack to article page
