Simplified geological map of the Valsassina northern sector. The Val Biandino Intrusive Suite is divided into two units: the “Val Biandino Quartz-Diorite” (VBQD) and the “Valle di San Biagio Granite” (VSBG). The VBQD crops out in a tectonic window bounded by the Grassi Shear Zone (GSZ; Froitzheim et al., 2008) and the Sassi Rossi Normal Fault (SRNF; Sciunnach, 2001b) intruding the late Variscan metamorphic basement of the central Southern Alps. The VSBG crops out in small erosional windows to the NW of the SRNF, below the Lopingian Permian Verrucano Lombardo. Analysed samples are reported in the map. A, B, C, and D are the four major stocks of the VBQD
