The Hematite Question: Hydrogen‐Driven Magnetization of Hematite‐Bearing Sandstones and Insights for Natural Hydrogen Exploration

open access: yesGeophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Natural hydrogen is a promising clean energy resource, but locating subsurface accumulations remains challenging. Aeromagnetic anomalies are increasingly utilized as a rapid and cost‐effective tool for geological hydrogen prospection, particularly associated with magnetite formation during abiotic geochemical hydrogen generation through ...

Crustal Magma Storage and Plumbing System Beneath the Tianchi and Wangtian'e Volcanoes, Changbaishan Intraplate Volcanic Field, China and North Korea

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.
Abstract The Changbaishan volcanic field, which includes the Tianchi and Wangtian'e volcanoes in China and the Namphothe volcano in North Korea, is one of the most complex and hazardous volcanic regions on Earth due to its tectonic setting and explosive Holocene activity.

Evidence from Strandings for Geomagnetic Sensitivity in Cetaceans [PDF]

open access: yes, 1986
We tested the hypothesis that cetaceans use weak anomalies in the geomagnetic field as cues for orientation, navigation and/or piloting. Using the positions of 212 stranding events of live animals in the Smith sonian compilation which fall within the ...

Aeromagnetic survey of Kansas

open access: yesEos, Transactions American Geophysical Union, 1981
An aeromagnetic survey of Kansas, conducted by the Kansas Geological Survey during the past 5 years, has been completed. The total intensity magnetic field contour map, along with spectrally filtered versions, reveals largescale magnetic patterns, which we correlate with basement composition and paleotectonics.A second vertical derivative map clearly ...

Robust Directional Analysis of Magnetic Microscopy Images Using Non‐Linear Inversion and Iterative Euler Deconvolution

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In paleomagnetism, bulk measurements of entire samples have traditionally been used to characterize remanent magnetization. While effective, this approach provides only a general directional estimate and cannot resolve spatial variability or magnetization at the grain scale.

Aeromagnetic survey in Kusatsu-Shirane volcano, central Japan, by using an unmanned helicopter

open access: yesEarth, Planets and Space, 2021
Kusatsu-Shirane volcano is one of the active volcanoes in Japan. Phreatic explosions occurred in Mt. Shirane in 1983 and most recently, in 2018, in Mt. Motoshirane.

Mantle Dynamic Topography of the Fringing Oceanic Basins of Antarctica

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Dynamic mantle processes are known to influence oceanic basins with implications for ocean circulation and climate. This study exploits an interdisciplinary approach to probe present‐day mantle and lithosphere beneath Antarctica's fringing oceanic basins to better understand sub‐crustal processes and implications for the continental realm.
