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