Eocene Tectonic Change in the South Pacific Caused Exhumation of the Transantarctic Mountains in Northern Victoria Land, Antarctica

open access: yesNew Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
Apatite fission‐track and (U‐Th)/He data indicate rapid exhumation of northern Victoria Land at 40–30 Ma, correlating with opening of Adare Trough at 43–28 Ma. Exhumation was greatest close to the Ross Sea, consistent with other regions of the Transantarctic Mountains.

Rainfall Variability and Extremes in the Hamassa Sub‐Basin, Ethiopia: Past Trends and Future Risks

open access: yesMeteorological Applications, Volume 33, Issue 2, March/April 2026.
This study assessed spatial variability and temporal trends in the historical (1986–2023) and projected precipitation regime of the Hamassa sub‐basin. The results indicate a significant drying trend during the main cropping season, marked interannual and spatial variability, and associated linkages to warm‐phase ENSO events, which delay the onset and ...

The SCEC Community Rheology Model for the Southern California Lithosphere: Geological Framework, Ductile Flow Laws, and Preliminary Implications

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The Southern California Earthquake Center (SCEC) Community Rheology Model (CRM) comprises a three‐dimensional geologic framework model (GFM) of southern California's lithosphere, and synthetic aggregate ductile flow laws applicable to each GFM rock type under low‐strain conditions. Given temperature, volatile content, pressure, and strain rate,

Magnetic‐A: The New R‐Based Toolbox for Analysis of Paleomagnetic Data

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Paleomagnetic remanence in rocks and sediments provides a unique means to constrain stratigraphic records in both space and time. This is because of the symmetry of the paleomagnetic field with respect to Earth's spin axis over geological time, and the global synchronicity of magnetic field reversals.

Subduction Zone Magnetism: The Influence of Metamorphism and Serpentinization in the Mantle Wedge

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.
Abstract Subduction zone magnetic anomalies have previously been used to infer their thermal structure assuming a uniformly serpentinized mantle carries a homogeneous, isotropic magnetization. However, seismic tomography, geological observations and numerical modeling provide increasing evidence for a non‐uniformly serpentinized mantle wedge that may ...
