The Central Iberian arc, an orocline centered in the Iberian Massif and some implications for the Variscan belt

International Journal of Earth Sciences, 2011
An arcuate structure, comparable in size with the Ibero-Armorican arc, is delineated by Variscan folds and magnetic anomalies in the Central Iberian Zone of the Iberian Massif. Called the Central Iberian arc, its sense of curvature is opposite to that of the Ibero-Armorican arc, and its core is occupied by the Galicia-Tras-os-Montes Zone of NW Iberia ...

Geodynamic Evolution of the Iberian Massif

1990
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.

The structure of a major suture zone in the SW Iberian Massif: the Ossa-Morena/Central Iberian contact

Tectonophysics, 2001
Abstract We have investigated the stratigraphy, structure and metamorphism of the boundary between the Ossa Morena Zone (OMZ) and the Central Iberian Zone (CIZ), two significant continental portions of the Variscan Iberian Massif. The OMZ/CIZ contact is marked by a strongly deformed and metamorphosed NW–SE trending narrow band, namely, the Central ...

Some aspects of paleoweathering in the Iberian Hercynian Massif

CATENA, 1990
Summary The Iberian Hercynian Massif occupies most of the western half of the Iberian Perninsula and forms the basement over which Mesozoic, Cenozoic and Quaternary materials rest unconformably. Over it can be found remains of weathering profiles that are fossilized by marine and/or continental sediments of different ages.

Revised biochronology of the Lower Cambrian of the Central Iberian zone, southern Iberian massif, Spain

Geological Magazine, 2010
AbstractTrilobites from the upper unit of the Lower Cambrian Pusa Formation (south-central Spain) substantially antedate other Iberian trilobites, according to widely published correlation schemes, and arguably would be among the earliest trilobites globally.

Geochemistry and EPR of cassiterites from the Iberian Hercynian Massif

Mineralogical Magazine, 1997
AbstractThis paper is based on microprobe analysis (Ta, Nb, Fe, Mn, Ti, W, Sn) and Fe3+ EPR spectra of cassiterite samples from 14 tin deposits from the Iberian Hercynian Massif. The interpretation of microprobe data, atomic ratios (Fe+Mn)/(Nb+Ta), and Fe3+ EPR spectra reveal that the coupled substitution: 3Sn4+ = (Fe,Mn)2+ + 2(Nb,Ta)5+ is dominant in ...

The Cadomian orogeny in the Iberian Massif revisited

Geological Society, London, Special Publications
The exposed basement of the Variscan Iberian Massif includes various remains of the accretionary Cadomian orogen that fringed the northwestern margin of Gondwana in the late Neoproterozoic–Terreneuvian. Subduction of the Mirovoi Ocean beneath Gondwana was responsible for the formation of an arc system that was finally accreted to the continental margin.

Comparative study of the Lower Ordovician ironstones of the Iberian Massif (Zamora, Spain) and of the Armorican Massif (central Brittany, France)

Journal of Sedimentary Research, 1998
Abstract The Lower Ordovician ironstones of the Iberian Massif (Zamora) and of the Armorican Massif (central Brittany) occur in units of varying thickness (0.2-2.5 m). They are interstratified in mainly sandy formations, with numerous sedimentary structures and trace fossils showing that they were deposited in a nearshore environment (
