From: Messinian or Pleistocene valley incision within the Southern Alps

Fig. 2

Cross sections in the Adige Valley, the Lago di Garda and Po Plain showing the valley fill and the depth of the sediment bedrock unconformity (locations see Fig. 1). All profiles have a twofold vertical exaggeration, the drilling location is marked as a dotted line. a Laas section in the Vinschgau, seismic interpretation (modified after Brardinoni et al. 2018). b Rabland Partschines section 10 km upstream from Sinich. Seismic interpretation (modified after Savi et al. 2014). c Sinich section, the profile is based on seismic data and a drill hole and shows the sediment infill on the erosional unconformity that is interpreted Messinian in age (modified after Bargossi et al. 2010). Note that it is unknown if the valley bottom is U or V shaped, the original seismic line was not perpendicular to the valley. d Trento section was drilled to the pre LGM sediments but not into the basement rock (modified after Avanzini et al. 2010). e Riva (Lago di Garda), the section is in the not in today’s Adige valley (Castellarin et al. 2005). f Crema (Po Plain), this section represents the incision, presumably Messinian, of the Serio or Adige river in the Po Plain (modified after Amadori et al. 2018). Note that the crema profile is in the subsiding Po Plain, the restored incision depth here is on the order of 750 m
