Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract Marine sediments contain magnetic mineral particles of detrital, biogenic and authigenic origin that record changes in the direction and intensity of the geomagnetic field over geological time. Previous studies have demonstrated that the recording efficiencies of detrital and biogenic magnetite differ.

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.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract The study of variations in geomagnetic field intensity over time and space is crucial to understand the evolution of the geodynamo and its interactions with the Earth's surface. In this work, we introduce the SAGEOMAG (South America GEOMAGnetic) database, a comprehensive and updated repository of geomagnetic field intensity records derived ...

The Significance of Magnetic Fabrics Preserved in Hydrothermally Altered Rocks
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Anisotropy of Magnetic Susceptibility (AMS) and Anisotropy of Magnetic Remanence (AMR) are critical petrofabric tools for investigating the evolution of volcano‐magmatic, tectonic, and surface process systems. These highly sensitive techniques can distinguish multiple magnetic fabrics within individual samples, crucial in assessing archives of

Early Solar Wind and Dynamo Magnetic Field Topology Predictions for (16) Psyche and Other Asteroids
Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract Asteroid (16) Psyche is a metal‐rich body that might record an ancient coherent magnetization if some relict crust or mantle is preserved. Herein, we use magnetohydrodynamic simulations to predict (16) Psyche's field topology for several distinct pathways: (i) an early solar wind‐induced magnetization imparted after a larger body was impacted,

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Widespread aeolian loess‐paleosol and red clay sediments on the Chinese Loess Plateau (CLP) provide a globally unique terrestrial archive of Neogene–Quaternary climate. However, the timing and associated mechanisms of red clay to loess‐paleosol shift remain debated.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Reconstructing oroclinal orogens along the Fuegian Andes‐northern Antarctic Peninsula provides critical constraints on the pre‐opening tectonic evolution of the Drake Passage, although such efforts are limited by a lack of reliable Cretaceous paleomagnetic and geochronological data.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Deep‐sea rare earth elements and yttrium (REY)‐rich sediments have attracted considerable attention since their discovery in 2011. However, the environmental factors controlling REY enrichment remain poorly understood, largely because paleoceanographic proxies are absent in pelagic clays.
