Late Paleozoic Iberian Orocline(s) and the Missing Shortening in the Core of Pangea. Paleomagnetism From the Iberian Range

Supercontinents are usually interpreted to be single and rigid continental plates. How and when Pangea became a rigid supercontinent is disputed, and age estimations vary from ~330 to ~240 Ma. The Gondwana‐Laurussia collision formed the …

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 …

Progressive orocline formation in the Eastern Pontides–Lesser Caucasus

The Eastern Pontides–Lesser Caucasus fold–thrust belt displays a peculiar northwards arc-shaped geometry that was defined as an orocline in earlier studies. The Lesser Caucasus was affected by two main tectonic events that could have caused orocline …

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 …

Paleomagnetism.org: an online multi-platform open source environment for paleomagnetic data analysis

This contribution provides an overview of Paleomagnetism.org, an open-source, multi-platform online environment for paleomagnetic data analysis. Paleomagnetism.org provides an interactive environment where paleomagnetic data can be interpreted, …

New kinematic constraints on the Ibero-Armorican orocline: a paleomagnetic study from the Peñalba syncline and the Truchas Synform, NW Spain

The Cantabrian orocline is a large structure that bends the Variscan orogen of Western Europe in NW Iberia. The extensively studied kinematics of its core, the foreland of the orogen, indicates that the structure is secondary, i.e. acquired after the …
