Abstract

The Iberian Massif represents the largest continuous exposure of pre-Permian rocks within the Iberian Peninsula (Fig. 1). It was first described in terms of a coherent tectonic unit by Staub (1926) who considered it to be comprised of Archean basement sequences that had been successively reworked during Caledonian and Herycnian orogenic events. Stille (1924, 1929) contested these ideas and argued, instead, that the Iberian Massif largely records the effects of Hercynian tectonothermal events. This was later documented in more detail by Lotze (1945), who divided the massif into six zones on the basis of contrasting lithologic, structural and/or metamorphic characteristics (Fig. 1). With the advent of plate tectonic concepts, a new view of the Iberian Massif emerged, and many different geodynamic plate models were proposed. Van der Voo (1982) suggested that the Iberian Massif constituted the southwesternmost and largest piece of the so-called Armorican plate, a continental block which appears to have rifted from Gondwana in the early Paleozoic.
