Deformation, fluid flow, and mass transfer in the forearc of convergent margins: A two-day field trip in an ancient and exhumed erosive convergent margin in the Northern Apennines

This guide provides background information and an itinerary for a two-day fi eld trip in the Northern Apennines leaving from Modena and ending at Riolunato (Modena). The proposed fi eld trip route leads through the Po Valley side of the Northern Apennines, in the Emilia region. The fi eld trip provides opportunities to examine the exposed geological features related to a phase of early-middle Miocene convergence between the European and Adria plates. In particular, outcrops have been selected that exhibit features characterizing deformation in an exhumed plate boundary shear zone, interpreted as an erosive plate boundary shear zone. The sedimentary evolution and deformation of the upper and lower plates are also highlighted.
