Rotation in the Southeastern Caribbean Arc (Grenadines) Accommodated by Back‐Arc Basin Inversion

Tectonics, Volume 45, Issue 4, April 2026.
Abstract The Caribbean tectonic plate is typically modeled as a rigid plate moving along discrete plate boundaries. Isolated exposures on islands have long shown that above the Lesser Antilles subduction zone, the plate experienced contractional, strike‐slip, and extensional deformation, but the importance of this deformation remained long unknown ...

Magnetic‐A: The New R‐Based Toolbox for Analysis of Paleomagnetic Data

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Paleomagnetic remanence in rocks and sediments provides a unique means to constrain stratigraphic records in both space and time. This is because of the symmetry of the paleomagnetic field with respect to Earth's spin axis over geological time, and the global synchronicity of magnetic field reversals.

Late Carboniferous Geomagnetic Field Events Recorded in Post‐Collisional Altenberg–Teplice Caldera, Variscan Belt

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Characteristic remanent magnetizations isolated from the late Variscan Altenberg–Teplice Caldera exhibit paleomagnetic directions, ranging from those consistent with the expected primary Late Carboniferous geomagnetic field to intermediate directions that significantly diverge from the dipole states.

Reconstructing Late Pleistocene to Prehistorical Holocene Geomagnetic Field Variations From La Palma Lava Flows (Canary Islands, Spain): Unraveling Viscous Components

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We present new vector paleomagnetic data from 13 radiometrically dated lava‐flows in southern La Palma (Canary Islands) spanning from 1 to 56 ka, which covers most of the Late Pleistocene to prehistoric Holocene volcanic record in the island.

Paleomagnetic constraint of the age and duration of the Taupō Eruption, New Zealand

Earth, Planets and Space, 2023
We have carried out paleomagnetic analyses of tephras from the Taupō eruption, one of the most violent eruptions on Earth in the past 5000 years. Pyroclastic deposits were collected with 7 cm3 cubes pushed into each unit of the Taupō eruption sequence ...

Paleomagnetic Pole Positions and Geomagnetic Secular Variation from the Cretaceous Ponta Grossa Dike Swarm (Brazil)

Geofísica Internacional, 2015
A detailed paleomagnetic and rock magnetic investigation has been carried out on the Early Cretaceous Ponta Grossa dike swarm in southern Brazil. This formation seems an excellent target for paleomagnetic study.

New Insights Into the Proposed Geomagnetic Excursion Hilina Pali From High‐Resolution Lake Sediment Cores From the Polar Ural Mountains, Arctic Russia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract This study presents paleomagnetic records from three 24 m‐long sediment cores from the neighboring lakes Bolshoye Shchuch'ye and Maloye Shchuch'ye, located about 10 km apart in the Polar Urals in northern Russia. The age model, based on radiocarbon dating and varve counting, shows that the sediment sequences reach back up to about 23.5 ka cal.

Bending the Sierra Madre Oriental: A Paleocene Orocline

Tectonics, Volume 44, Issue 11, November 2025.
Abstract The Sierra Madre Oriental belt of the Mexican thin‐skinned fold‐and‐thrust belt, which formed during the Late Cretaceous due to the subduction of the Farallon Plate beneath North America, exhibits a pronounced curvature of approximately 100°, concave to the southwest.
