dc.description.abstractThe contribution of asthenosphere diapirs to the exhumation of Orogenic Lherzolites from the mantle to the Earth’s surface stands as a major issue in the evolution of orogenic belts. Structural and textural data from the Carratraca massifs of the Ronda peridotites, in the Betic Cordillera of southern Spain, provide evidence for a narrow mantle diapir that was formed in Early Miocene times. Its development spent 1.1 Ma at an ascent rate of less than 4.5 mm/y. When set in its geological and petrological context, this diapir documents the injection of hot asthenosphere into older and cooler lithospheric mantle, in response to the delamination of the thickened lithosphere keel formed during the Mesozoic and Cenozoic convergence of the African and Iberian plates from Cretaceous times onwardsen_US
