Tectonics on Early Earth Driven by Earth's Changing Shape During Tidal Recession of the Moon
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.Abstract Few fragments of Earth's earliest crust have survived, and so this formative period of our planet's history is shrouded in mystery. To leverage the limited data available, it is important to understand all the processes that could have shaped our young planet.

Preferential Orientations of Subjovian Patera and Northern Hemisphere Mountain Populations on Io
Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.Abstract Io's surface hosts numerous mountains and volcanic paterae generated by processes that occur at depth, including tidal heating and the resultant crustal recycling and subsidence stresses. Global trends in the shape and orientation of surface features could provide insight into these subsurface processes.

Multiscale Modeling of the Mantle Rheology
, 2018 Le projet de recherche Modélisation multiéchelle de la rhéologie des minéraux du manteau (dont l’acronyme anglais est RheoMan) a été lauréat de l’ERC (European research Council) suite à l’appel d’offre Advanced Grant de 2011. Il visait à proposer une nouvelle approche de la rhéologie du manteau basée sur une approche de physique des minéraux qui ...

Rheology of the Earth's mantle and geodynamical processes
Geophysical Research Letters, 1991 A non‐linear integral rheological model consistent with general creep theory and laboratory studies of rock creep is proposed to describe the rheology of the Earth's mantle. This model is universal, i.e., relevant to all strains, stresses and timescales. For constant stresses the model behaves like a power law non‐Newtonian fluid.

Mechanical Decoupling Across the Deep Megathrust Boundary
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.Abstract We examine stress and strength across the deep subduction plate boundary at ∼60 km depth offshore northeastern Japan, near the downdip seismic limit of the megathrust. High‐frequency (2–5 Hz) moment tensor inversion of ∼2,000 M 2–3.5 earthquakes, integrated with existing catalogs, increases the number of focal mechanisms by more than a factor ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 11, November 2026.Abstract Fluid‐rock interactions have major implications on the frictional behavior of fault rocks. Infiltration of CO2‐bearing fluids in ultramafic fault zones causes the progressive formation of serpentinite, talc‐magnesite (soapstone) and quartz‐magnesite (listvenite) assemblages.

Melt Production and Volatile Release From Thermochemical Mantle Plumes
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Mantle plumes are thought to generate Large Igneous Provinces (LIPs), the largest outpourings of lava in the geologic record, which are associated with long‐lasting climatic warming events and mass extinctions. However, the controls on mantle degassing by plumes remain poorly constrained.

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Studies of postseismic creep often infer a strong reduction in upper‐mantle viscosity after large earthquakes, yet the microphysical mechanism responsible for this behavior remains subject of debate. Here, we present new gas‐medium apparatus experiments at 1100–1200°C on pre‐dried, annealed Åheim dunite (grain size of 400 μ ${\upmu }$m ...

Rheology of Indian continental crust and upper mantle
Journal of Earth System Science, 1991 A rheological model of the Indian shield has been constructed using the thermal structure derived from available surface heat flow and heat generation data and the flow properties of characteristic minerals and rocks like quartz, diabase and olivine which respectively represent the upper crust, lower crust and upper mantle.

Superpiles: The Impact of Mantle Temperature on Large Low Velocity Provinces
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Among the most prevalent features in Earth's deep mantle are the Large Low Velocity Provinces (LLVPs), hypothesized to be hotter and compositionally distinct from the surrounding mantle. LLVPs have previously been viewed as either active superplumes rising through the mantle or passive piles shaped by large scale convection.
