Plume‐Driven Subduction Termination in 3‐D Mantle Convection Models
Geochemistry, Geophysics, GeosystemsThe effect of mantle plumes is secondary to that of subducting slabs for modern plate tectonics when considering plate driving forces. However, the impact of plumes on tectonics and planetary surface evolution may nonetheless have been significant.

Siberian flood basalt magmatism and Mongolia-Okhotsk slab dehydration [PDF]
, 2008 Experimental data combined with numerical calculations suggest that fast subducting slabs are cold enough to carry into the deep mantle a significant portion of the water in antigorite, which transforms with increasing depth to phase A and then to phase ...

Mantle Dynamic Topography of the Fringing Oceanic Basins of Antarctica
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.Abstract Dynamic mantle processes are known to influence oceanic basins with implications for ocean circulation and climate. This study exploits an interdisciplinary approach to probe present‐day mantle and lithosphere beneath Antarctica's fringing oceanic basins to better understand sub‐crustal processes and implications for the continental realm.

Origin and thermal evolution of Mars [PDF]
The thermal evolution of Mars is governed by subsolidus mantle convection beneath a thick lithosphere. Models of the interior evolution are developed by parameterizing mantle convective heat transport in terms of mantle viscosity, the superadiabatic ...

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract The fractal dimensions of lava flow margins on Earth often correlate with their flow morphologies and have been used to tentatively identify flow morphology on other rocky planets where fine‐scale observations are limited. Previous studies of lava flow margins on Venus have reported fractal dimensions (D) mostly within the range between 1.05 ...

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Mercury's tectonic record is dominated by shortening landforms, including lobate scarps, high‐relief ridges and wrinkle ridges. Previous analyses of these structures have used displacement–length ratios to constrain the planet's global contraction to a range of either no more than 2 km or up to 7 km.

Evolution of midplate hotspot swells: Numerical solutions [PDF]
The evolution of midplate hotspot swells on an oceanic plate moving over a hot, upwelling mantle plume is numerically simulated. The plume supplies a Gaussian-shaped thermal perturbation and thermally-induced dynamic support.

Journal of Geophysical Research: Planets, Volume 131, Issue 4, April 2026.Abstract Previous analyses of Mercury's tectonic record have arrived at widely varying amounts of global contraction. Contraction also varies spatially, with some regions displaying a near‐zero record of contraction. Here, we investigate the contribution of membrane–flexural strain from lithosphere loading to the tectonic record.

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.Abstract Seamounts are submarine volcanic features that record the tectonic and magmatic evolution of Earth's interior, yet their global distribution remains poorly resolved due to sparse high‐resolution bathymetric coverage. We present a weakly supervised deep learning framework that integrates gravity and bathymetric data to enable global‐scale ...
