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.

Geomagnetic paleointensity dating of South China Sea sediments for the last 130 kyr
, 2009 Relative paleointensity records from the northern South China Sea, northwest Pacific Ocean were studied in two gravity piston cores. Continuous mineral magnetic and paleomagnetic measurements were made using discrete sediment samples.

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.

Application of an Anisotropy‐Based Correction to Relative Paleointensity Estimates of Experimentally Deposited Sediments [PDF]
Geochemistry, Geophysics, Geosystems, 2018 AbstractThe magnetization of a sediment is acquired when ferromagnetic detrital particles align with the Earth's magnetic field as they settle through the water column. The relative continuity and ubiquity of the global sedimentary record makes sediments and sedimentary rocks an ideal target for studies of relative paleointensity (RPI) and the ...

Impact Plasma Amplification of the Ancient Mercury Magnetic Field
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Spacecraft measurements of Mercury indicate that it has a core dynamo with a surface field of 200–800 nT. These data also indicate that the northern hemisphere crust contains remanent magnetization likely produced by an ancient magnetic field. The inferred magnetization intensity is consistent with a wide range of paleofield strengths (0.2–50 ...

Geochemistry, Geophysics, Geosystems, 2020 Gyro‐remanent magnetization (GRM) is a frequently occurring yet unwanted remanence contamination for certain samples during alternating field (AF) demagnetization of the natural remanent magnetization.

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Understanding the mechanisms linking low‐latitude monsoon variability and high‐latitude ice‐sheet discharge is critical for elucidating past atmospheric teleconnections, yet direct evidence for such linkages during the last glacial period remains limited. Here we present a high‐resolution terrigenous input record from the South China Sea (SCS)
