Reproducing past subduction and mantle flow using high-resolution global convection models

open access: yesEarth and Planetary Physics, 2018
Plate subduction drives both the internal convection and the surface geology of the solid Earth. Despite the rapid increase of computational power, it remains challenging for geodynamic models to reproduce the history of Earth-like subduction and ...

D‐Rex++: A New Tool to Simulate Olivine's Crystallographic Preferred Orientation in the Upper Mantle With Grain Size‐Coupled Rheology

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Understanding the co‐evolution of olivine's crystallographic preferred orientation (CPO) and grain size is essential for capturing the dynamics of Earth's upper mantle. Existing CPO evolution models, such as D‐Rex, successfully predict CPO development but overpredict CPO strength and do not provide a physically meaningful grain size, limiting ...

Geologically Recent Formation of Some Tesserae on Venus by Plains Deformation

open access: yesJournal 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 ...

Mineralogical Evidence for Highly Evolved Th‐Saturated Magma on Mars

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Thorium‐rich (Th‐rich) geological units have been detected by remote sensing in the Martian crust. However, there is still a lack of mineralogical evidence to constrain the magmatic processes responsible for these anomalies. In this study, we report the first discovery of thorite (ThSiO4) grains within a zircon fragment from Martian regolith ...

Mantle transition zone thickness beneath Ross Island, the Transantarctic Mountains, and East Antarctica

open access: yesGeophysical Research Letters, 2008
The thickness of the mantle transition zone beneath Ross Island, and parts of the Transantarctic Mountains and East Antarctic Craton has been mapped using data from the 2000–2003 Transantarctic Mountain Seismic Experiment to determine if, as indicated by
