“…The complexity of Piemonte geology is the result of a continuous geodynamic process which, since the Rhaetian-Hettangian, led to the formation of two continental 'passive' margins: the 'Palaeo-European Margin' and the 'Palaeo-Adriatic Margin', and two oceanic zones: the Liguria-Piemonte Domain and the Valais Domain (Bernoulli & Jenkins, 2009;Bertotti, Picotti, Bernoulli, & Castellarin, 1993;Dal Piaz, 1974;1999;Dal Piaz, Bistacchi, & Massironi, 2003;Dal Piaz, Hunziker, & Martinotti, 1972;Dewey & Bird, 1970;Dewey, Pitman, Ryan, & Bonnin, 1973;Handy, Schmid, Bousquet, Kissling, & Bernoulli, 2010;Mohn, Manatschal, Müntener, Beltrando, & Masini, 2010;Sturani, 1975;Trumpy, 2001). Since the Late Cretaceous, the European and Adriatic continental plate margins began to converge (Le Pichon, 1968) inducing the subduction of the interposed oceanic lithosphere.…”
