Fig. 5: Tectonic and exhumation history of the northeastern shoulder of the L’Aquila Intermontane Basin.

Left panel: Summary of the dolomite TL ages framed within the available tectono-stratigraphic temporal constraints for the D1 syn-orogenic thrusting and D2 post-orogenic extension stages in the central Apennines. Right panel: Schematic exhumation and tectonic history at the footwall of the Monte Marine Fault (MMF) along the northeastern shoulder of the L’Aquila Intermontane Basin as reconstructed from the dolomite TL ages. (a) Syn-orogenic exhumation of the carbonate bedrock; (b) Possible resetting of the dolomite TL signal along the nascent MMF zone; (c) Final exhumation of the MMF zone caused by the westward propagation of the extensional faulting and opening of the L’Aquila Intermontane Basin.
