dc.description.abstract The Pyrenees are an ESE – WNW trending, Alpine cordillera built after the collision between the Iberian and Euro-Asian plates from Late Cretaceous to Early Miocene. This mountain belt extends 450 km between the Mediterranean Sea and the Atlantic Ocean but from a geological point of view the Pyrenean Orogen extends for more than 1000 km from Provenza (France) to the Cantabrian Mountains and their continental platform under the Cantabrian Sea (Alonso et al., 1996; Pulgar et al., 1996, 1997; Gallastegui, 2000). Neo-proterozoic to Cenozoic, rocks appear in this Alpine orogen. The pre-Cambrian and Paleozoic rocks are affected by variscan deformation and metamorphism and are outcropping in a large belt in the core of the cordillera. These rocks are flanked to the south and to the north by large outcrops of Mesozoic and Cenozoic rocks. The Alpine deformation gave rise to the development of E – W trend thrusts, which involved previously deformed pre-Cambrian and Paleozoic basement rocks. These thrusts caused shifts and rotations of large blocks of basement rocks with an Alpine deformation restricted to narrow bands and the development of a tectonic foliation represented mainly to west of the Pyrenees (Choukroune & Seguret, 1973; Autran y García-Sansegundo, 1996; Izquierdo-Llaval, 2014). This situation makes necessary to carry out a revision about main features of the Alpine Orogen as well as of Paleozoic of the Pyrenees and The Variscan Orogen of which preMesozoic rocks were part. es_ES
