Tyrrhenian–Central Apennines Orogenic Evolution: A “Zip-Like” Model

Over the past 25 million years, the Tyrrhenian–Central Apennines system evolved through the interplay of slab rollback and inherited rifted margin structures. 25–20 Ma: Oceanic subduction and slab rollback form the Liguro-Provençal back-arc basin and the thin-skinned Liguride accretionary wedge. 20–12 Ma: Soft collision begins as Adria’s rifted continental margin reaches the subduction zone. Deformation remains thin-skinned, slowing thrust propagation. 12–10 Ma: Hard collision shifts the subduction interface into the ductile middle crust. Contraction decouples into thin- and thick-skinned tectonics, slab rollback resumes, and lower crust delamination accelerates thrusting and back-arc extension. 10 Ma–Present: Lower crust delamination drives foreland-dipping low-angle normal faults, opening the Tyrrhenian back-arc basin. Deformation is controlled by a migrating singularity point where compressional and extensional structures meet. Paper link: https://doi.org/10.1016/j.earscirev.2...
