Palaeogeographic map of the Alpine Tethys preceding the Tertiary collision of Europe and Adria (modified after Masson 2002; Bernoulli et al. 2003; Gianreto Manatschal, personal communication; Galster et al. 2012). The regional distribution of the different continental and oceanic units is deduced from the kinematic model of the Central Alps discussed in this paper, with emphases on the European continental margin and the Valais basin. The green star indicates the position of the Sabbione basaltic volcano (Carrupt 2002)
