2D-schematic sketches showing the geometry and relationships between deformation phases: a pre-coupling D1 and D2 folds geometry inside EPZ unit; b D2-related deformation of the IPZ/DM tectonic contact (blue line) and D2 folds geometry inside coupled IPZ and DM unit; c T1 coupling between IPZ + DM and EPZ, and related Top-to-E shear zones (green lines; see text); d D3 folds re-orienting previous T1 shear zone; e D4 folds and coeval T2 shear zones superposed T1 shear zones; f Summary of deformation relative timing, highlighting the nearly coeval development of the shearing events with D2 and D4 folding phases
