Deformation structures that pre-date development of the SFZ (D1, D2). a F1 folds refolded by F2 in calcschist, Sion-Courmayeur Zone, footwall (649898/123263). b F1 folds refolded by F2, with development of an S2 axial plane schistosity in calcschist, Sion-Courmayeur Zone, footwall (649384/123073). c S2 crenulation cleavage overprinting the main S1 foliation, psammite, Houillère Zone, hanging-wall (635033/122807). d Synthetic sketch of the principal deformation phases observed on an outcrop scale, hanging-wall (635083/122450)
