Fig. 7From: The 3D interplay between folding and faulting in a syn-orogenic extensional system: the Simplon Fault Zone in the Central Alps (Switzerland and Italy)Synthetic sketch of the complexly deformed region around the Simplon Pass, showing the overprinting relationships. Sm2: younger ductile-to-brittle mylonitic foliation related to the SFZ; Sm: older ductile mylonitic foliation related to the SFZ; S1 and S2: pre-existent regional fabric associated with the D1–D2 deformation phase; F2: Fold axis related to the tight to isoclinal post-nappe refolding D2, F4: Fold axis related to the D4 backfolds in the Northern Steep BeltBack to article page
