Resolving the Internal Magnetic Domain Structure of Cloudy Zone Tetrataenite

open access: yesGeophysical 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.

An attempt to determine the microwave paleointensity on historic Paricutín volcano lava flows, Central Mexico [PDF]

open access: yesGeofísica Internacional, 2003
We report a preliminary rock-magnetic and microwave paleointensity study of historic lava flows between 1943 and 1948 of Paricutín volcano. These lava flows show well-preserved, well-exposed, fresh and extensive outcrops.

Characterization of Magnetic Mineral Assemblages in Clinkers: Potential Tools for Full Vector Paleomagnetic Studies

open access: yesGeochemistry, Geophysics, Geosystems, 2021
High‐quality paleointensity data are essential for improving our understanding of the geomagnetic field; however, it is challenging to find materials that reliably record full vector magnetization going back in time.

Analysis of an Updated Paleointensity Database (QPI‐PINT) for 65–200 Ma: Implications for the Long‐Term History of Dipole Moment Through the Mesozoic

open access: yesJournal of Geophysical Research: Solid Earth, 2019
The global paleointensity database for 65–200 Ma was analyzed using a modified suite of paleointensity quality criteria (QPI) such that the likely reliability of measurements is assessed objectively and as consistently as possible across the diverse data

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes

open access: yesGeochemistry, 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.

New contributions to the Early Pliocene geomagnetic field strength: Case study of southern Caucasus volcanics [PDF]

open access: yesGeofísica Internacional, 2000
We carried out a Thellier paleointensity study on a ~ 3.8 My Pliocene lava flow succession from Georgia (southern Caucasus). Previous paleomagnetic studies on this succession revealed that eight consecutive lava flows record a reverse polarity direction ...

Eruptive timing and 200 year episodicity at 92°W on the hot spot‐influenced Galapagos Spreading Center derived from geomagnetic paleointensity

open access: yesGeochemistry, Geophysics, Geosystems, 2014
Eruptive timing in mid‐ocean ridge systems is relatively poorly constrained, despite being an important variable in our understanding of many mid‐ocean ridge processes, including volcanic construction; magma recharge, flux, and storage; and the stability

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway

open access: yesGeochemistry, 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.
