Tectónica de inversion en el sector central del Arco Vasco (Cuenca Vasco-Cantábrica)

Abstract

We report the existence of a thrust system in the central part of the Basque Arc (Basque-Cantabrian basin, Guipúzcoa). From bottom to top, the thrust system is formed by theAia, Pagoeta and Azpeitia allochthonous sheets. The kinematic and structural analysis provides a top to the NE movement, and reveals the widespread reactivation of normal faults during the Pyrenean inversion tectonics
