Comparing Paleointensity Recording Efficiencies of Detrital and Biogenic Magnetite by Deposition Experiments With Synthetic Sediments

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.

Marine Magnetic Anomalies Enhanced by Internal Stress in Rapidly Cooled Submarine Basalts

Geophysical Research Letters
Marine magnetic anomalies are pivotal to our understanding of plate tectonics, geomagnetic fields, and deep Earth dynamics. However, the question of how Ti‐rich titanomagnetites, the primary remanence carriers in oceanic crust rocks, can faithfully ...

The Fine‐Scale Magnetic History of the Allende Meteorite: Implications for the Structure of the Solar Nebula

AGU Advances, 2021
Magnetic fields in the early solar system may have driven the inward accretion of the protoplanetary disk (PPD) and generated instabilities that led to the formation of planets and ring and gap structures.

On the reliability of drilling core reorientations using palaeomagnetic methods: A case study from the boreholes in the Tarim Basin

地质科技通报, 2023
Objective This study explores the accuracy of drilling core reorientations by using remanent magnetization. Methods To this end, paleomagnetic analyses were carried out on 43 Silurian sandstone samples collected from five boreholes (TKQ101, SHUN9, TAT19,

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.

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,

The Paleo‐Tethys Suture Zone in the Afghan Hindu Kush‒Pamir: Geo‐Thermochronology, Geochemistry, Tectonics

Tectonics, Volume 45, Issue 3, March 2026.
Abstract In the Afghan Hindu Kush, the 223–209 Ma (≤800°C) Salang batholith is part of the Silk‐Road magmatic arc that was built on ∼40‐km‐thick Turan‐Karakum block continental crust. The batholith constitutes the hanging wall of the Herat‐Panjshir‐Badakhshan—the Paleo‐Tethys—suture zone, vestige of the subducted Paleozoic‐early Mesozoic Paleo‐Tethys ...

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

Meteoritics &Planetary Science, Volume 61, Issue 3, Page 405-426, March 2026.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...
