Acquisition of Self‐Reversed Magnetization in Greigite Driven by Antiparallel Vortex‐Core Coupling During Low‐Temperature Oxidation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Self‐reversed magnetization, acquired antiparallel to the external field, can complicate the interpretation of paleomagnetic directional records, particularly in altered greigite‐bearing sediments with anomalous magnetizations. The underlying physical process for this self‐reversal remains poorly constrained.

Resolving the Internal Magnetic Domain Structure of Cloudy Zone Tetrataenite

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Recent advances in magnetic imaging can directly capture the internal magnetization of natural and synthetic materials at resolutions <10 nm. This capability opens new possibilities to determine the magnetic domain state of ferromagnetic minerals that are fundamental for recording and retaining paleomagnetic records.

Reconciling Paleomagnetism and Pangea. [PDF]

, 2012
Although an array of geological and geophysical data support the conventional (Wegenerian) paleogeographic model of Pangea in the Late Triassic-Early Jurassic, its configuration in pre-Late Triassic time has remained controversial for the last half ...

Quickly erupted volcanic sections of the Steens Basalt, Columbia River Basalt Group: Secular variation, tectonic rotation, and the Steens Mountain reversal

Geochemistry, Geophysics, Geosystems, 2008
The Steens Basalt, now considered part of the Columbia River Basalt Group (CRBG), contains the earliest eruptions of this magmatic episode. Lava flows of the Steens Basalt cover about 50,000 km2 of the Oregon Plateau in sections up to 1000 m thick.

Slow True Polar Wander Around Varying Equatorial Axes Since 320 Ma

AGU Advances
True polar wander (TPW), the rotation of the solid Earth relative to the spin axis, is driven by changes in the Earth's moment of inertia induced by mantle convection and may have influenced past climate and life. Long‐term TPW is typically inferred from

Acquisition of chemical remanent magnetization during experimental ferrihydrite-hematite conversion in Earth-like magnetic field-implications for paleomagnetic studies of red beds [PDF]

, 2015
Hematite-bearing red beds are renowned for their chemical remanent magnetization (CRM). If the CRM was acquired substantially later than the sediment was formed, this severely compromises paleomagnetic records.
