Stereographic projections of structural data (equal-area, lower-hemisphere), divided by relative chronology of deformative and intrusive events. Legend: D1+2: circles = poles of S1+2 (111 data from Valscura, 89 data from Val du Haut Boréon); open squares = mineral lineations on S1+2 (4 data from Val du Haut Boréon); open circles = poles of axial planes of D2 folds (12 data from Valscura, 4 data from Val du Haut Boréon); open triangles = axes of D2 folds (9 data from Valscura, 2 data from Val du Haut Boréon). D3: circles = poles of S3 (17 data from Valscura); open circles = poles of axial planes of D3 folds (10 data from Valscura, 7 data from Val du Haut Boréon); open triangles = axes of D3 folds (8 data from Valscura, 15 data from Val du Haut Boréon). Lamprophyres: circles = poles of dyke walls (195 data from Valscura, 116 data from Val du Haut Boréon); grey circles = poles of leucocratic veins (11 data from Val du Haut Boréon); open squares = amphibole-supported lineations in comb layers (15 data from Val du Haut Boréon). D4: circles = poles of mylonitic foliations (76 data from Valscura, 56 data from Val du Haut Boréon); open squares = stretching lineations on D4 shear zones (6 data from Valscura, 4 data from Val du Haut Boréon); open diamonds = poles of D4 stylolitic and mylonitic foliations along lamprophyre dyke walls (15 data from Valscura; 19 data from Val du Haut Boréon).
