Images of different field-scale structures. Interference relationships between S1 (dashed black lines) and S2 (dashed white lines) folds in a calcschist + paragneiss in EPZ and in b metagabbro + serpentinite in IPZ. c D3 box-folds (conjugated S3 axial planes dashed red lines) deforming Sm1 mylonitic foliation (dashed white lines) in the mylonitic calcschist of the SSZ. d A3 (dashed red lines) crenulation lineations in metabasalt. e D4 folds (S4 axial planes dashed orange lines) deforming S2 regional foliation (dashed white lines) in calcschist of the IPZ. f T1-realted Top-to-E shear sense marked by a sigma-shaped exotic block wrapped by the Sm1 mylonitic foliation (dashed white lines) in the mylonitic calcschist of the SSZ. g T1-related kinematic indicators (Top-to-E C-planes in red, Sm1 dashed white lines) in mylonitic calcschist. h T2-related S–C structures (C-planes in orange) showing Top-to-W kinematism deforming S2 regional foliation (dashed white lines), in calcschist of the IPZ
