List of Figures

1. Tectonic sketch of Western Alps (modified after Dal Piaz, 1999) showing the location of the Sesia-Lanzo Zone (SL); red diamond locates the mapped area of Fig 2.
2. Structural map of the southern slope of Mt. Mucrone with foliation trajectories traced on standard lithological information.
3. Representative structures characterising low, medium and high degree (LD, MD and HD, respectively) of fabric evolution during the successive deformation stages (D1-D6) in the two main types of metagranitoids.
4. Representative structures characterising low, medium and high degree (LD, MD and HD, respectively) of fabric evolution during the successive deformation stages (D1-D6) in the two main types of country rocks.
5. Qualitative estimate of the degree of fabric evolution during foliation development, starting from originally foliated or initially isotropic rocks, as proposed by Salvi et al. (2010)
6. Representative microstructures of low, medium and high degree (LD, MD and HD, respectively) of fabric evolution during the successive deformation stages (D1-D5) in the two main types of metagranitoids.
7. Representative microstructures characterising low, medium and high degree (LD, MD and HD, respectively) of fabric evolution during the successive deformation stages (D1-D6) in the two main types of country rocks.
8. Maps of the degree of fabric evolution (D1 and D2) and metamorphic transformation (M2) for D1 and D2 stages.
9. Maps of the degree of fabric evolution (D3 and D4) and metamorphic transformation (M4) for D3 and D4 stages.
10. Compositional range of amphiboles from metaintrusives (a, b) and metasediments (c, d).
11. Pyroxene compositions according to Morimoto (1988) for Cpx in metaintrusives and metasediments.
12. Garnet compositional variations in metasediments and metaintrusive rocks.
13. Examples of compositional zoning in Grt from pargneisses, zoisitites and grey-type metagranitoids.
14. Phengite compositions in metasediments and intrusive rocks displayed in the ternary diagram of Massonne & Schreyer (1987) and in the Si/Mg (in a.p.f.u.) plot.
15. PT paths inferred for the Mt. Mucrone rocks
