Fig. 2.  Field evidence for leucocratic melts and high temperatures synkinematic to the left-lateral deformation. (a) Syn-left-lateral shear leucocratic dykes; 1 to 3 from older to younger. Modified from Leloup et al. (1993, fig. 12a). (b) Several generations of syn-left-lateral shear leucocratic dykes. Deformation and age decrease with increasing numbers. Modified from Leloup et al. (1993, fig. 12b). (c) Sketch of boudinaged amphibolitic layers with leucocratic melts (stippled pattern) (from Leloup et al. 1995, fig. 14e). (d) Oblique view of outcrop C1 showing several generations of leucocratic dykes, some of which have been dated (Sassier et al. 2006). Less deformed, intermediate and more deformed dykes appear respectively in purple, yellow and orange. (e) Garnets synkinematic to the left-lateral deformation. Top: helicitic garnet, polished rock slab. Bottom: garnet in migmatitic paragneiss; view from above. (f) Migmatitic paragneiss with left-lateral shear planes (from Leloup et al. 1995, fig. 15b). View from above. (g) High-temperature orthogneiss with melted patches around the and type feldspars. Modified from Leloup et al. (1995, fig. 16a). View from above.
