Terrane Collision‐Induced Subduction Initiation: Mode Selection and Implications for Western Pacific Subduction System

open access: yesGeochemistry, Geophysics, Geosystems
In the regime of plate tectonics, the subduction of an oceanic plate generally terminates with the collision and accretion of continental terranes. Then, a new subduction zone may form in the neighboring oceanic plates, which is defined as the terrane ...

Terrestrial Analogs to Titan for Geophysical Research

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Mesoscale and Submesoscale Variability in the Indian Ocean

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract Material transport and air‐sea coupling dynamics associated with monsoon‐related mesoscale and submesoscale processes in the Indian Ocean significantly modulate biogeochemical cycles, the large‐scale energy balance, and both regional and global climate change.

Intraplate Basalts in Eastern Continental China Record the Subduction History of the Pacific Plate

open access: yesGeophysical Research Letters
To assess whether intraplate magmatism in eastern continental China records the subduction history of the Pacific plate, we plotted elemental compositions of the volcanic rocks in this region since the Early Cretaceous as a function of age.

Arc Heat Flow and Magmatic Heat Budgets

open access: yesReviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

New Magnetite Reference Material for SIMS δ18O Measurements and a Study of Precision and Accuracy Due to Crystal Orientation Effects

open access: yesGeostandards and Geoanalytical Research, Volume 50, Issue 2, Page 391-406, June 2026.
Key Points A new magnetite reference material (PF21mt) is available for δ18O measurements by SIMS. Reproducibility of measurement results in two laboratories suggest orientation bias of ±2‰ (2s) at 20 keV. Repeatability improves to ±1‰ (2s) when using a 13 keV protocol, suggesting reduced orientation bias. In situ isotope ratio measurements provide the

Upright emplacement of the Gibraltar slab and the origin of rifting in adjacent foreland and Backarc Basins

open access: yesCommunications Earth & Environment
Back-arc basins in subduction systems usually form following discrete subduction-related extension stages. However, in the westernmost Mediterranean, the initiation of Cenozoic extension associated with the Valencia Trough and Algerian Sea Basin ...
