garnet-staurolite-kyanite schists + subvolcanic dykes (Vogel & Voll 1976)
Spillmann 1993 S.26: Die Tonale Serie ist eine inhomogene, präalpin hochmetamorphe Glimmerschieferserie mit Pegmatiten und Karbonat- und Amphibolitlinsen. Die Tonale Serie ist eng mit der ebenfalls inhomogen Pietra Rossa Fm verfingert; die Ausdehnung der Tonale Serie wird dementsprechend sehr unterschiedlich dargestellt.

p.99: The largest part of the Tonale Nappe is characterized by a very distinct and lithologically variable association of predominantly sillimanite-bearing paragneisses, marbles, quartzites and amphibolites metamorphosed during the Variscan cycle, referred to as the Tonale Gneiss Complex (formerly “series”).
