Fig. 3

Orogen-perpendicular and -parallel cross-sections illustrating the upper crustal structure of the Tauern Window. Large parts of cross-sections 2 and 2bis (b) follow a profile published by Brandner et al. (2008) and data from Töchterle (2011); all others are constructed according to published and unpublished maps of the Geologische Bundesanstalt of Austria, as well as own data that include extrapolations based on contouring of the most important tectonic boundaries (Scharf 2013). Note that the scale of the cross-sections in Fig. 3a differs from that of Fig. 3b, c. See Fig. 4 for the cross-section traces. a Orogen-parallel sections; cross sections 1 and 1bis represent alternatives discussed in the text. b Orogen-perpendicular sections across the western Tauern Window; cross-sections 2 and 2bis represent alternatives discussed in the text. c Orogen-perpendicular sections across the central and eastern Tauern Window
