The E-vergent Northern Apennines formed by Oligocene-Miocene convergence and westward subduction of Adria beneath Europe. Extension ensued in the Mid-Late Miocene reflecting lower plate roll-back causing opening back-arc Tyrrhenian Sea. Post-orogenic extension is commonly advocated as main driver exhumation belt's inner domain high-pressure/low-temperature (HP-LT) rock units. Acquadolce Subunit...

New SHRIMP U-Pb zircon ages for the Portalegre and Alcáçovas orthogneisses document a complex pre- Variscan history for the Iberian basement in Portugal. The available geochemical and geochronological data for the Alcáçovas orthogneiss (ca. 540 Ma) tend to favor its involvement in a Cadomian orogenic event. This is consistent with the development of an active continental margin setting at the e...

The denudation budget of the Alps is quantified for the main period of lateral extrusion between 22 and 12 Ma. The relative importance of tectonic denudation increases from W to E from ,70% in the Lepontine window in the Swiss Alps to ,80% in the Tauern window and to more than 95% in the Rechnitz window. The driving mechanism of tectonic denudation was eastward extrusion due to an unconstrained...

Abstract. The dynamics of growing collisional orogens are mainly controlled by buoyancy and shear forces. However, the relative importance these forces, their temporal evolution impact on tectonic style orogenic wedges remain elusive. Here, we quantify forces during orogeny investigate wedge formation exhumation crustal rocks. We leverage two-dimensional petrological–thermomechanical numerical ...
