Central Iberia

Tangled up in folds: tectonic significance of superimposed folding at the core of the Central Iberian curve (West Iberia)

The amalgamation of Pangea during the Carboniferous produced a winding mountain belt: the Variscan orogen of West Europe. In the Iberian Peninsula, this tortuous geometry is dominated by two major structures: the Cantabrian Orocline, to the north, …

Paleomagnetism in Extremadura (Central Iberian Zone, Spain)

**Introduction:** The winding Variscan belt in Iberia, featuring the Cantabrian orocline (NW Iberia) and the Central Iberian curve, is a foremost expression of the late Carboniferous amalgamation of Pangea, which produced remagnetizations spanning …

Bootstrapped Total Least Squares orocline test: A robust method to quantify vertical axis rotation patterns in orogens, with examples from the Cantabrian and Aegean oroclines

Most mountain belts on Earth show some degree of curvature in plan view, from a slight bend to horseshoe shapes. Such curvatures may occur on different scales, from individual thrust sheets to entire plate boundaries. Curvature may be acquired by …

Paleomagnetism of the Central Iberian bend's hinge: too many oroclines in the Iberian variscides

The Variscan mountain belt in Iberia defines a large “S” shape with the Cantabrian Orocline in the north and the Central Iberian curve, an alleged orocline belt of opposite curvature, to the south. The Cantabrian Orocline is kinematically well …

One or two oroclines in the Variscan orogen of Iberia? Implications for Pangea amalgamation

The supercontinent Pangea formed in the late Carboniferous as a result of the Gondwana-Laurussia collision, producing the strongly sinuous Variscan–Alleghanian orogen. Iberia is interpreted to comprise two Variscan bends, forming an S-shaped orogenic …
