p.76: In analogy to the Ilanz Zone, the Carboniferous– Permian metasedimentary rocks consist of graphitic schist, chlorite schist, psammitic to psephitic gneiss and metavolcanic layers (NIGGLI 1944, LABHART & RENNER 2012). The greenschist-facies metamorphic conditions of these rocks are defined by the chlorite, albite and
sericite-dominated mineral assemblages with minor biotite, epidote, garnet and rare chloritoid (Fig.15).
