Beschreibung

Beschreibung

Berger et al. 2017 p.78: The Piora-Peiden Zone includes a number of different tectonic slices, which are not differentiated on the present map sheet (FREY 1967, VÖGELI et al. 2013). The local names of these slices are reported in VÖGELI et al.(2013 and references therein). The Piora-Peiden Zone is characterised by incomplete sequences of Triassic and Early Jurassic metasedimentary rocks. One significant difference with respect to adjacent Mesozoic units is the more dominant Late Triassic Quarten Formation. The Early Jurassic units are equivalent to those of the Scopi Zone (see above), comprising tectonically reduced parts of the Stgir and Inferno Formation.

p.39: The Piora-Peiden Slice Complex is a set of thin slices that occur continuously from Airolo to Ilanz between the Gotthard or Scopi nappes to the north and the Leventina-Lucomagno or Grava nappes to the south. These slices consist of Triassic to Early Jurassic sediments similar to those of the Scopi Nappe. As this slice complex underwent a first Alpine metamorphic phase of high pressure (Wiederkehr et al. 2008), it could also be considered as Lepontic.
