Field pictures of D₃ deformation. (A and B) Low-angle S₃ reworking a steep S₂ foliation. Both foliations are melt-bearing and a pegmatitic leucosome parallels C₃ shear bands. The outcrop is located near the Gioberney mountain refuge. (C) Melt-bearing flat-lying D₃ shear zone cross-cutting the steep S₂ foliation. Outcrop photographs A, B C and D are located around the Gioberney mountain refuge, in the La Meige Block. (D) Vertical shortening of S₂ and development of axial planar S₃. (E) Mylonitic S₃ with top-to-the-NW shearing at the base of the Cortical Pelvoux, near Villard-Notre-Dame village. (F) Moderately dipping migmatitic gneiss (MCE 330) showing a solid-state protomylonitic foliation S₃ developed during D₃ shearing and cooling.
