Using Venus, Earth, and Mars to Understand Exoplanet Volatile and Climate Evolution
Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract Venus, Earth, and Mars exhibit a wide range of interactions between their deep interiors, surfaces, lower and upper atmospheres, and the Sun, with commensurate variations in the nature of their atmospheres and evolution of their volatiles. By examining these worlds' characteristics and behavior, we can gain some understanding of the breadth of

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.Abstract The Planetary Instrument for X‐ray Lithochemistry (PIXL) onboard the Perseverance rover has characterized the composition of Martian regolith at a scale of hundreds of microns using micro‐focus X‐ray fluorescence spectroscopy. PIXL data reveal a diverse population of regolith grains with distinct spectral, chemical, and crystallographic ...

Survey and Modeling of Windblown Ejecta Deposits on Venus
AGU Advances, Volume 6, Issue 5, October 2025.Abstract Venus' thick atmosphere rotates in the same direction as the solid body, but ∼60 times faster. This atmospheric superrotation has produced dozens of windblown ejecta deposits (“parabolas”) on the surface of Venus. The formation and modification of parabolas is an interplay between impacts, aeolian modification, and atmospheric dynamics.

Investigating the Antarctic Lithosphere Through Sp Receiver Function Analysis
Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract To better understand the lithosphere of Antarctica, we imaged its lithosphere‐asthenosphere boundary (LAB) and crust‐mantle transition using Sp receiver functions from teleseismic events analyzed at individual stations and with common conversion point stacking. Results reveal a prominent negative velocity gradient at depths of 70–100 km across

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract Eastern North America has hosted significant historical earthquakes, where seismicity clusters along tectonically inherited structures. Using the spherical finite‐element code CitcomSVE and fully 3D viscosity structure, we model the intraplate stress response to glacial isostatic adjustment (GIA) using ICE‐6G, both with and without low ...

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.Abstract A novel high‐resolution, non‐destructive method for diagenetic screening of fossil corals for geochronologic and paleoclimatic studies using neutron computed tomography (NCT) is proposed. NCT circumvents limitations of traditional techniques, such as destructive sampling and 2‐D imaging by providing detailed 3‐D visualizations of coral ...
