Research experience in Petrology, Geochemistry and Geochronology of igneous and metamorphic rocks, as well as in the dynamics of orogenic wedges. Research focused on the study of the origin and tectonothermal evolution of the terranes which constitute the Allochthonous Complexes of the Iberian Massif. This research has been continued during many years and finally has allowed to suggests correlations between Galicia and Trás-os-Montes (Portugal), SW Iberia and also through the Ibéro-Armoricano arc until Brittany. Significant results on the chronology of the Variscan high-P metamorphic events and the age and meaning of the ophiolites involved in the Variscan Orogen. Important advances also in the knowledge about the provenance and isotopic sources of the Allochthonous Terranes and the Iberian Authochton. This research experience has been applied to the development of paleogeographic models for the Paleozoic in the peri-Gondwanan context and during the assembly of Pangea. The interest of future research is focused on the correlation of the sutures defined in the basement of western and central Europe, through an improved knowledge on the chronology and composition of the associated ophiolites and their mantle section, the high-P metamorphism and the involved isotopic sources.
