Model‐Predicted Shear‐Wave‐Splitting Parameters in NE Japan: Comparison With Observations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract We model olivine crystal preferred orientation (CPO) and shear wave splitting (SWS) in the mantle wedge, using the results of a 3‐D numerical thermomechanical model for the NE Japan subduction zone. The model predicts a quasi‐2‐D trench‐normal (E‐W) mantle wedge flow pattern beneath Tohoku, given the trench‐normal subduction, but a more ...

Quantifying Water Ice in Regolith Mixtures via Infrared (1.2–2.5 μm) Reflectance Model Parametrization

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Water ice deposits occur on inner solar system bodies in sunlit and shadowed terrains. We develop approaches to remotely determine the mixing mode with regolith (areal vs. intimate), ice grain size, and abundance that reveal processes of ice formation, emplacement, and evolution.

Mapping the Western Jezero Crater Rim From Orbit: Connections to Regional Geologic Units and Context for Exploration by the Mars 2020 Perseverance Rover

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The Mars 2020 rover is currently traversing the western rim of Jezero, a Middle to Late Noachian‐aged crater formed by an impactor that struck the northwest edge of Isidis Planitia (hereafter referred to as the Isidis basin) on Mars. Previous studies suggest that pre‐Isidis basin and Noachian outcrops are preserved throughout this region ...

Experimental Aeolian Abrasion of Basalt Sands as an Analog for Producing Martian Dust

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract Dust covers a significant portion of Mars' surface, with dust storms periodically engulfing the planet. Despite this, the origins of Martian dust are poorly understood, especially for ancient dust deposits. To address this deficit, we conducted experiments to replicate the mechanical abrasion of saltating sand grains in a Martian desert dune ...

Quantifying Natural Hydrogen‐Helium Sources and Dynamic Accumulation in Global Sedimentary Basins

Earth's Future, Volume 14, Issue 10, October 2026.
Abstract Despite the scientific and economic importance of hydrogen and helium, their crustal budgets remain poorly quantified. This study systematically assesses the accumulation of natural hydrogen and helium in global sedimentary basins by integrating predictive models for both gases with H2/He ratios.

Pyroxene mineralogies of near-Earth vestoids.

, 2009
We have calculated pyroxene mineralogies of seven near-Earth asteroids (NEAs) with reflectance spectra similar to HEDs (howardites, eucrites, and diogenites). Two different sets of formulas (Gaffey et al. 2002; Burbine et al.

Spectral Reflectance Properties (0.3–2.5 μm) of Mesosiderites and Pyroxene+Metal Mixtures

The Astrophysical Journal Supplement Series
To date, the parent body of mesosiderites remains uncertain. Some candidate bodies have been proposed, including 4 Vesta and 16 Psyche. In this study, we performed a comprehensive spectroscopic survey of mesosiderites and pyroxene+metal mixtures to ...

Mantle Wedge Metasomatism During Subduction Initiation: Mineral Transformations and Fluid Fluxes (BOIC Ophiolite, Newfoundland)

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The soles of ophiolites preserve slices of oceanic crust metamorphosed to amphibolite‐ to granulite‐facies conditions beneath heavily deformed mantle peridotites, providing key records of fluid and mass transfer across nascent subduction interfaces.
