Fig. 3From: Eclogitic metamorphism in the Alpine far-west: petrological constraints on the Banchetta-Rognosa tectonic unit (Val Troncea, Western Alps)modified from Corno et al., 2021); D2 folds transpose S1 compositional banding and develop S2 axial plane schistosity, D3 tectono-metamorphic event is expressed by S3 crenulation cleavagea Lithostratigraphic succession of the North La Grangia section. Red polygon shows the location of the analyzed sample, used for P–T pseudosection modeling. Acronyms are: CBm, Ab + Chl micaschist; a, quartzite levels; b, Cld + Ph-bearing glaucophanic schist; c, fine-grained gneiss; d, metabasite body with meta-aplites (white bodies); CBq, Ph-bearing quartzite; b Field photograph of the metabasite body (d) within the Ab + Chl micaschist of the North La Grangia section. The main foliation (S1) is highlighted by whitish meta-aplites layers and is sub-parallel to primary lithological surface, S2 grows in axial plane of D2 folds; c Lithostratigraphic succession of the Vallonetto section. Red polygons show the location of analyzed samples, used for P–T pseudosection modeling. Acronyms are: CVpm, Jd-bearing gneissic micaschist; CVbm, Gr-bearing micaschist; m, Tlc + Aeg-bearing impure marble; CVm, Cld-bearing micaschist; g, Cld-bearing glaucophanite bodies; fg, fine-grained gneiss; dq, dark quartzites; d Field photograph of Jd-bearing gneissic micaschist of the Vallonetto section (Back to article page
