Geomagnetic Variability in a Post‐Superchron Geodynamo: Insights From the Deccan Traps
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Studying long‐term geomagnetic field behavior is crucial for understanding Earth's evolution, as field variability reflects processes in the planet's deep interior. One key question concerns the relationship between field strength and polarity reversal frequency, particularly during the Cretaceous Normal Superchron (CNS), a prolonged interval ...

Formation of Asteroid (16) Psyche by a Giant Impact
Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract Asteroid (16) Psyche is the largest likely metal‐rich asteroid in the Solar System and the target of the NASA Psyche mission. The mission aims to determine whether the asteroid is the core of a differentiated planetesimal that lost its mantle via a giant impact.

The Birth of Paleomagnetism in Latin America: Argentina [PDF]
, 2013 Paleomagnetic activities in Latin America started with the first field trip of the young Ken Creer in 1957. In the early sixties, and by initiative of the by then Director of the Department of Geological Sciences at the University of Buenos Aires, Feliz ...

Revisiting the Jurassic Geomagnetic Reversal recorded in the Lesotho Basalt (Southern Africa)
, 2003 We carried out a detailed and continuous paleomagnetic sampling of the reversed to normal geomagnetic transition recorded by some 60 consecutive flow units near the base of the Lesotho Basalt (183 1 Ma).

New Mesozoic and Cenozoic data help constrain the age of motion on the Altyn Tagh fault and rotation of the Qaidam basin. [PDF]
, 2002 In order to better understand the tectonic evolution of central Asia under the influence of the India-Asia collision, we carried out a paleomagnetic study of 1500 cores from 106 sites along the Altyn Tagh fault, in the Qaidam and Tarim basins, and on the

The Gannon Storm's Impact on Electric and Magnetic Fields in Italy: A Regional Perspective
Space Weather, Volume 24, Issue 1, January 2026.Abstract The intense May 2024 geomagnetic storm provided an opportunity to conduct the first analysis of geoelectric hazards in Italy. Data from three geomagnetic observatories and a magnetotelluric station were analyzed to examine the spatiotemporal evolution of storm‐induced variations.

Paleomagnetism of a lateritic paleoweathering horizon and overlying Paleoproterozoic red beds from South Africa: Implications for the Kaapvaal apparent polar wander path and a confirmation of atmospheric oxygen enrichment [PDF]
, 2002 The Olifantshoek Group in southern Africa contains Paleoproterozoic red beds that are exceptionally well preserved, lying unconformably atop a regionally extensive lateritic paleoweathering profile.

Tectonics, Volume 45, Issue 1, January 2026.Abstract Recent observations and drilling campaigns have challenged the typical models for rifted margins by providing evidence for the existence of intermediate cases between the magmatic and amagmatic end‐members. In this contribution, we document the evolution of the Central Campos rifted margin, located in southeast Brazil, based on a combined ...

Early Jurassic magnetostratigraphy and paleolatitudes from the Hartford continental rift basin (eastern North America) . . . [PDF]
, 2008 To determine whether the ~200 Ma central Atlantic magmatic province (CAMP) coincides with a normal polarity bias and a purported abrupt change in polar wander at the J1 cusp, we collected samples for paleomagnetic study from 80 sites distributed over a ...
