p.430: The Teggiolo zone is the autochthonous sedimentary cover of the Antigorio and Verampio nappes. Its age ranges from Triassic to Eocene and it comprises several sedimentary cycles composed of Triassic quartzites, metapelites and dolomites, Jurassic to Lower Cretaceous marbles and Upper Cretaceous to Tertiary flysch and wildflysch, separated by erosive surfaces and large stratigraphic gaps. The main mass of the Teggiolo calc-schists, whose base truncates the Triassic–Jurassic cycles and the Antigorio basement consists of flysch deposits of Late Cretaceous to Eocene age of the North-Penninic (or Valais s.l.) basins. Thus, the Antigorio-Teggiolo domain occupies a palaeogeographic position at the boundary between the Helvetic and Penninic realms (Matasci et al. 2011). A 10 m thick band of calcite marble exposed along the Sentiero dei Vanisc (VANISC on map Fig. 2) is attributed to the Upper Jurassic of the Teggiolo zone.
