Two‐Layer Anisotropy Beneath Subduction Zones: Bayesian Inversion

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Shear‐wave splitting measurements have the potential to constrain multiple layers of anisotropy and thereby enhance depth resolution. Using the formulation of Silver and Savage (1994, https://doi.org/10.1111/j.1365‐246x.1994.tb04027.x), previous studies have employed deterministic grid‐search approaches to identify best‐fitting two‐layer ...

Geologically Recent Formation of Some Tesserae on Venus by Plains Deformation

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Tessera is a pervasively deformed terrain type on Venus generally interpreted as the oldest preserved material on the surface. Large expanses of this terrain type are typically elevated and have been hypothesized to be felsic, perhaps analogous to Earth's continents and even to date from an era with a more Earth‐like climate earlier in Venus ...

Low steady-state stresses in the cold lithospheric mantle inferred from dislocation dynamics models of dislocation creep in olivine

, 2015
International audienceTransmission electron microscopy observations on olivine crystals deformed at moderate (≤1273 K) temperature evidenced dislocations interactions explaining the hardening observed in the experiments, but also recovery mechanisms by ...

Carbonate- and silicate-metasomatized mantle beneath Himalayan-Tibetan orogenic belt

Communications Earth & Environment
The extreme geochemical enrichment of post-collisional potassium-rich lava in the Alpine-Himalayan orogenic belt has led researchers to hypothesize that enrichment is inherited from a metasomatized mantle source potentially incorporating crustal ...

A Machine Learning Approach for Volcanic Eruption Mass Estimation

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Estimation of total volcanic erupted mass—the primary metric of eruption magnitude—is typically performed post‐eruption relying on dense monitoring of ground‐based seismology, gravity and deformation instrumentation, and therefore exists for only ∼100 of ∼1280 volcanoes worldwide.

Thick Underplating and Buoyancy of the Bermuda Swell

Geophysical Research Letters
Bermuda is an intraplate ocean swell that does not conform to traditional mantle plume theory. Unlike other prominent bathymetric swells, such as Hawaii, it lacks age‐progressive volcanism, a deeply rooted mantle plume, and modern volcanism.

Magnetization of the lithosphere and the upper mantle based on magnetic-mineralogical data

Геофизический журнал
According to numerous studies, sources of magnetic anomalies in the lithosphere and mantle can have a magnetic-mineralogical nature due to magnetic minerals at mantle depths.

Subducting Slab Thermo‐Petrologic Structure and Intermediate‐Depth Supra‐Slab Earthquakes Beneath Southern Colombia

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We develop 2‐D thermo‐petrologic models for two transects through southern Colombia and compare the model‐predicted temperature distributions and depths of slab dehydration with seismological observations. Along the northern transect, earthquakes occur above the relatively young subducting Nazca slab at 80–160‐km depths.

Lithospheric mantle domains beneath Antarctica

, 2005
The chemistry of mafic volcanic rocks and minor intrusions erupted on continents can be used to define sub-continental asthenospheric and lithospheric mantle sources. Data have been collated from Antarctica and the Falkland Islands (adjacent in Gondwana)
