From supercontinent to superplate: Late Paleozoic Pangea's inner deformation suggests it was a short-lived superplate

The supercontinent cycle explains how landmasses amalgamate into supercontinents that dismember after a ~ 100 Myr tenure in a quasi-periodic manner. Supercontinents are thought to be rigid superplates whose formation controls many of the Earth's …

Palaeomagnetism from multi-orogenic terranes is ‘not a simple game’: Pyrenees' Palaeozoic warning

Palaeomagnetism is a versatile tool in the Earth sciences: it provides critical input to geological timescales and plate tectonic reconstructions. Despite its undeniable perks, palaeomagnetism is not without complications. Remagnetizations …

Cretaceous to Miocene NW Pacific Plate Kinematic Constraints: Paleomagnetism and Ar–Ar Geochronology in the Mineoka Ophiolite Mélange (Japan)

The Mineoka Ophiolite Mélange is located at the intersection of the Pacific, Philippine Sea, Eurasian, and North American plates. The Mineoka ophiolite origin is disputed, and it has been ascribed to a fully subducted plate or part of the Pacific and …

Avalonia, get bent! – Paleomagnetism from SW Iberia confirms the Greater Cantabrian Orocline

The amalgamation of Pangea formed the contorted Variscan-Alleghanian orogen, suturing Gondwana and Laurussia during the Carboniferous. From all swirls of this orogen, a double curve in Iberia stands out, the coupled Cantabrian Orocline and Central …

The enigmatic curvature of Central Iberia and its puzzling kinematics

The collision between Gondwana and Laurussia that formed the latest supercontinent, Pangea, occurred during Devonian to early Permian times and resulted in a large scale orogeny that today transects Europe, northwest Africa, and eastern North …

Post-Eocene coupled oroclines in the Talesh (NW Iran): Paleomagnetic constraints

The Talesh Mountains (NW Iran) witnessed a long deformation history from the Triassic Cimmerian orogeny to the ongoing Arabia-Eurasia collision. This protracted multi-stage deformation has generated a remarkably curved orogen with a puzzling …

Towards FAIR Paleomagnetic Data Management Through Paleomagnetism.org 2.0

Scientific communities are placing an increasing emphasis on the implementation of data management protocols concerning data archiving and distribution. For instance, every proposal submitted to the European Horizon 2020 program, as well as to the …

Late/post Variscan orocline formation and widespread magmatism

The Paleozoic geology of Iberia is dominated by the tectonics of the Variscan orogeny and its aftermath. This defining geologic event was the result of large-scale collision that involved amalgamation of multiple continents and micro-continents, the …

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 …
