Photomicrographs of the metamorphic assemblages observed in the metasediments of the upper and lower units of the Piemont-Ligurian domain. Samples are located in Figs. 3 and 6 and Table 1. a Garnet relic with chloritoid and chlorite inclusion in the CIG0901 sample at Lago di Cignana (plane polarized light). b Garnet-chloritoid-phengite assemblage in the CIG0903 sample at Lago di Cignana (plane polarized light). c Garnet chloritoid-phengite assemblage in the GOL0812 sample at Gornergrat (plane polarized light). d Garnet partially replaced by chlorite and albite in the SZ0816 sample near Hörnlihütte (plane polarized light). e Relic garnet within albite porphyroblasts in the TRIF0805 sample near Trift (plane polarized light). f Sheared albite porphyroblast in the chlorite-phengite foliation in the CIG0915 sample at Lago di Cignana (crossed polars).
