p.73: In the region of Airolo, the scarcity of outcrops and the almost exclusive occurrence of meta-evaporites (Cornieule) does not allow a direct correlation between the metasedimentary sequences of the Termen-Nufenen Zone with those of the Val Piora. For this reason, the Termen-Nufenen Zone was terminated west of Airolo and, starting from there, a new unit comprising mainly Triassic meta-sedimentary rocks covering the crystalline rocks of the Gotthard Nappe to its eastern end was defined. This latter was called the Val Canaria-Lumbrein Zone. In the area east of the Val Piora, this unit has been often described as a relic of the autochthonous cover of the Gotthard Nappe (BERGER et al. 2005, VÖGELI et al. 2013
