Seismic imaging of the western Iberian crust using ambient noise: Boundaries and internal structure of the Iberian Massif [PDF]

open access: yesTectonophysics, 2013
We present new Rayleigh-wave dispersion maps of the western Iberian Peninsula for periods between 8 and 30. s, obtained from correlations of seismic ambient noise, following the recent increase in seismic broadband network density in Portugal and Spain ...

The Galicia–Ossa-Morena Zone: Proposal for a new zone of the Iberian Massif. Variscan implications [PDF]

open access: yesTectonophysics, 2016
Correlation of a group of allochthonous terranes (referred to as basal, ophiolitic and upper units) exposed in the NW and SW of the Iberian Massif, is used to propose a new geotectonic zone in the southern branch of the Variscan Orogen: the Galicia–Ossa ...

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 ...
