BaSIC: A Bayesian Inversion Model for Basalt Source Investigation and Characterization

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract We present BaSIC: Basalt Source Investigation and Characterization, an open‐source Python based Bayesian inversion method to constrain the source mineralogy of basalts. Using bulk rock geochemistry, the model takes the averages and standard deviations of six elemental ratios (Mn/Fe, Zn/Fe, Mn/Zn, Sc/Zn, Co/Fe, and Ga/Sc) for a given basalt ...

Intraplate volcanism off South Greenland: Caused by glacial rebound?

, 2012
Plate tectonic mechanisms explain most of the dominant types of volcanism. Intraplate volcanism has been attributed to hot spots associated with mantle plumes, though alternative explanations have been proposed for settings not fed by plumes.

Cenozoic Volcanic Provinces and Shallow Asthenospheric Volumes in the Circum‐Mediterranean: Evidence From Magmatic Geochemistry, Seismic Tomography, and Integrated Geophysical‐Petrological Thermochemical Inversion

Geochemistry, Geophysics, Geosystems
We compile an extensive catalog comprising geochemistry and ages of Cenozoic volcanic provinces in the Mediterranean region, distinguishing between three groups according to the geochemistry of magmatic rocks: intraplate (IVP), subduction‐related (SRVP),

Tectonic Inversion of the SCS from 3-D Magnetization Vector Clustering: Evidence for Differential Rotation and Ridge Jump

Applied Sciences
The eastern and southwestern sub-basins of the South China Sea (SCS) display starkly contrasting magnetic lineation patterns, yet quantitative 3-D mapping of the subsurface magnetic architecture—essential for deciphering basin evolution—remains ...

Scaling the Swell: Plume‐Lithosphere Interaction and Its Signal in Dynamic Seafloor Topography

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Hotspot swells provide key constraints for understanding plume‐lithosphere interaction. However, quantitative relationships between plume properties and swell morphology remain poorly constrained. Here, we use 3D regional geodynamic models with composite diffusion‐dislocation creep rheology to investigate plume‐lithosphere interaction for ...

Marine Geophysical Investigation of a Fault Ruptured During the 2012 Mw 8.6 Wharton Basin Earthquake

Tectonics, Volume 45, Issue 10, October 2026.
Abstract The 2012 Mw 8.6 and 8.2 Wharton Basin earthquakes, within an intraplate deformation zone in the Indian Ocean, are the largest instrumentally recorded strike‐slip earthquakes on Earth that challenged the prevailing view that great earthquakes occur only at well‐defined plate boundaries.

Three-Dimensional Magnetic Inversion with Mixed L_p Norm Regularization for Constraining the Crustal Architecture of Mesozoic Volcanic Arc in the Northern South China Sea

Applied Sciences
The high-magnetic anomaly belt in the northern slope of the South China Sea has long been associated with a Mesozoic volcanic arc. However, its crustal architecture remains unclear, limiting the understanding of its geological implications.

Magma Channeling and Crustal Structure of a STEP Fault From Integrated Geological and Geophysical Data: The Central Aeolian Volcanoes (Southern Tyrrhenian Sea)

Tectonics, Volume 45, Issue 10, October 2026.
Abstract Arc volcanism is commonly interpreted as the surface expression of subduction‐related magmatism and its spatial organization is often controlled by lithospheric structures. In arc‐back‐arc systems, slab retreat may promote the transition from compression to extension and the development of Subduction‐Transform Edge Propagator (STEP) faults ...
