QUATERNARY TECTONICS OF THE NORTHERN MARCHE REGI ON, AND IMPLICATIONS FOR ACTIVE DEFORMATION IN THE OUTER NORTHERN APENNINES

Abstract

The Quatemary tectonics of the northem Marche sector of the outer Northem Apennines has been analysed. Orogenic struc­tures within the study area include late Miocene - Pliocene, main­ly NE verging thrusts and associated folds whose geometry is locally controlled by gliding on oblique and lateral ramp segments. Post-orogenic features consist mainl y of normal and oblique-slip faults resulting from WSW-ENE oriented extension. [...]
