Ordovician geodynamics: The Sardic Phase in the Pyrenees, Mouthoumet and Montagne Noire massifs International Meeting (2017. Figueras, España), The Early Palaeozoic rift-related igneous activity recorded in the Iberian Massif is subdivisable into three main events separated by relatively quiescent episodes. The so-called Early, Main and late events represent space-temporal diachronic pulses characterized by a progressive variation in the nature of the rift-related magmatism. The first two, Early and Main rift-magmatic events, were defined in detail by Sánchez García et al. (2003) and are almost exclusive of the Ossa-Morena Zone (OMZ), while the late magmatic event mainly occurs in the Central Iberian (CIZ) and Galiza-Trás-os-Montes (GTMZ) zones (Ollo de Sapo Formation and associated plutons)., GeoBioTec, Departamento de Ciências da Terra, Universidade Nova de Lisboa, Portugal, Laboratório Nacional de Energia e Geologia, Portugal, Instituto Geológico y Minero de España, España, Instituto de Geociencias, Universidad Complutense de Madrid, España, Instituto de Geociencias, Consejo Superior de Investigaciones Científicas, España
