This fieldtrip is the continuation of the successful meeting in Rennes. The excursion will be focused on the correlation between Armorican and Iberian Massif, with special emphasis in the magnificent outcrops of the Allocthonous Terranes across the Cabo Ortegal, Órdenes and Malpica-Tui complexes.
On-site disscusions will focus on the broad theme of the late Palaeozoic Variscan-Alleghanian orogenesis issued from the collision of Gondwana and Gondwana-derived continental blocks with Laurussia and resulting in the amalgamation of Pangaea.

The field trip will visit the allochthonous complexes of Cabo Ortegal, Órdenes and Malpica-Tui, in northwestern Galicia, where units of the three allochthons are well represented, as well as localities in the Autochthon and Parautochthon. The first day would be devoted to the Autochthon and Parautochthon around the Cabo Ortegal Complex, visiting classic localities of the Ollo de Sapo Fm. as well as Late Ordovician diamictites and synorogenic deposits. The second day we would visit the Cabo Ortegal Complex, where rocks of oceanic affinity (Middle Allochthon) and HP-HT units of the Upper Allochthon crop out in an impressive landscape. During the third and fourth days, cross sections would be made across the ophiolitic to uppermost allochthon complexes in the E and W parts of the Órdenes Complex respectively. The fifth day will be devoted to the Lower Allochthon in the Malpica-Tui Complex.
