The Maggia-Sambuco nappe : stratigraphy, correlations and tectonic consequences (Central Alps). Swiss Geoscience Meeting, Abstract Volume 13 (Basel), 16–17
p.17: Above [the quartzite and dolomite of the Triassic] comes a thick formation of dark-coloured quartzitic micaschists, rich in garnet, with a few thin intercalations of orange limestone. It forms most of what has been mapped until now in this zone as “Bündnerschiefer”. We name it the Naret Formation. It shows remarkable similarities with the “untere und mittlere Granatschiefer” (Liszkay 1965) or with the “basale Stgir-Serie” (Baumer et al. 1961, Frey 1967) of the Gotthard sedimentary cover. We propose a latest Triassic (Rhaetian) to earliest Liassic age.
