Numerical Simulations of Sulfate Formation via the Diffusive Reaction Between Ca2+ in Volcanic Ash and SO2 Gas: Evaluation of SO2 Losses From Eruption Clouds During the 1991 Pinatubo Eruption

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Volcanic ash formed during explosive volcanism reacts with SO2 gas molecules in volcanic conduits and eruption clouds, resulting in the formation of CaSO4. When ash is removed from the eruption cloud, the SO2 gas molecule is scavenged from the eruption cloud. The CaSO4 growth is rate‐limited by Ca2+ diffusion at high temperatures.

Exploring the Formation and Age of Irregular Mare Patches (IMPs) to the Southeast of the Chang'e‐5 Landing Site

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Recently, possible exceptionally young mare volcanic glass beads were discovered in Chang'e‐5 (CE‐5) samples. Isotopic dating suggests an age of approximately 120 Ma, presenting new challenges to existing lunar thermal evolution models. Thus, our research focuses on the source region of Rima Mairan, a branch of Rima Sharp, and its surrounding ...

Multidisciplinary Analyses of Terrestrial Samples Used to Interpret an Inorganic Origin (Anhydrite:Ce3+) for the 304 and 325‐nm Doublet Fluorescence Detected by the Mars 2020 SHERLOC Instrument at Jezero Crater

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Doublet fluorescence at 304 and 325‐nm under deep ultraviolet (DUV) excitation was detected on Mars at Jezero crater by the Scanning Habitable Environments with Raman and Luminescence for Organics and Chemicals (SHERLOC) instrument onboard the Mars 2020 rover Perseverance.

Assessing Potential Landing Sites With Favorable Illumination and Accessible, Potentially Volatile‐Rich Permanently Shadowed Regions Within Artemis Candidate Landing Regions

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The lunar south pole features permanently shadowed regions (PSRs) that never receive direct sunlight. These regions maintain cold temperatures that potentially trap and accumulate volatiles over geologic timescales. Within NASA's Artemis candidate landing regions, we identified 130 candidate landing sites (CLSs) that satisfy the Human Landing ...

Exploring Terrestrial Lava Tubes as Martian Analogs (I): Multi‐Analytical Study of Mineralization Processes in Cueva del Vidrio, La Palma (Canary Islands)

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The study of terrestrial lava tubes is essential for understanding geological processes occurring during volcanic activity on other planetary bodies, such as Mars. These processes lead to the formation of minerals analogous to those found on other planets.

Rapid Seismic and Infrasound Assessment of Large Landslides: A Case Study From Denali National Park and Preserve (Alaska)

open access: yesJournal of Geophysical Research: Earth Surface, Volume 131, Issue 3, March 2026.
Abstract Large, rapid landslides are a global hazard that can occur in remote, mountainous areas. Eyewitness reports of landslides and satellite imagery can often be limited or delayed, particularly during inclement weather. However, landslide‐generated seismic and infrasound (low‐frequency atmospheric sound) waves can be remotely detected in near real‐

Pockmarks, Mud Volcanoes and Hydrocarbon Seeps in the Northern Gulf of Mexico: Trends and Controls on Widespread Fluid and Gas Venting

open access: yesBasin Research, Volume 38, Issue 2, March/April 2026.
Basin‐scale dataset reveals widespread hydrocarbon venting at the seafloor in the northern Gulf of Mexico. Hydrocarbon release at the seafloor is related to the occurrence of the underlying Louann salt and the gas hydrate stability zone. ABSTRACT The release of hydrocarbons, pore water and fluidized sediments impacts seafloor morphology, marine ...

Proceedings of a workshop on Lunar Volcanic Glasses: Scientific and Resource Potential [PDF]

open access: yes
This workshop on lunar mare volcanism was the first since 1975 to deal with the major scientific advances that have occurred in this general subject, and the first ever to deal specifically with volcanic glasses.

Moon's volcanic history revealed in glassy spherules from Apollo 17 soil 76501

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 3, Page 389-404, March 2026.
Abstract Rapidly quenched droplets of pyroclastically erupted lava are common in lunar regolith at landing sites proximal to the maria. Here, we document the U‐Pb chronologies, major element, and trace element compositions of picritic glassy particles from Apollo 17 regolith sample 76501. These particles are dominated by high‐Ti compositions similar to
