Fig. 1. Optical microscopy images using polarized and analyzed light of white micas studied with the microprobe: (a) TP627 - (b) TP492 - (d) TP752a: neocrystallized phengites from plagioclases during the shearing of the granodiorite by the Véronique fault; (c) TP492: Neoformed sigmoidal phengites in granodiorite and sheared with quartz recrystallization in pressure shadow.

Tab. 1. Analytical results table and corresponding calculated pressures of the biotites from the La Fourque granodiorite with the equation of Uchida et al. (2007) (data compiled from Lecouffe, 1987).

Tab. 2. Result of microprobe analyzes of white mica from E-W trending shear zones (Veronique and satellite faults) intersecting the La Fourque granodiorite. N correspond to the number of analyzes.

Tab. 3. Table of analytical results by electron microprobe of the hornblendes from la Fourque granodiorite (Soler, 1977) and the corresponding pressures calculated from the equations of Hammarstrom and Zen (1986); Hollister et al. (1987); Johnson and Rutherford (1989); Thomas and Ernst (1990); Schmidt (1992) and Mutch et al. (2016).
