GNGTS 2013 - Atti del 32° Convegno Nazionale

The results of the throw analysis show that the SVFS developed during the Mesozoic regional extension. Subsequently, it was reactivated during the Pliocene-Pleistocene flexuring, accommodating with a scissor movement the differential bending between the Lessini-Berici- Euganei block to the W and the Veneto-Friuli foredeep to the E. The results of this study don’t allow to recognize the most probably sinistral strike-slip component of the SVFS displacement, suggested by the GPS data (D’Agostino et al ., 2005; Grenerckzy et al ., 2005; Serpelloni et al ., 2005) and geodynamic reconstructions (Semenza, 1974; Castellarin and Cantelli, 2000; Massironi et al ., 2006). The fault system seems to be active at least until 20 ka as suggested by the U/Th dating carried out on a travertine deposit (Montirone Hill; Abano Terme) located in the hanging wall of the SVF (Pola et al ., in press).
