Silicate weathering in anoxic marine sediments

, 2009
Weathering of silicate minerals is the major sink for atmospheric CO2 on geological time scales. It has commonly been assumed that this process is only occurring on land. New results, however, show that silicate minerals are also reactive within marine sediments. Most of the metabolic CO2 being produced in marine sediments enriched in organic matter is

Quantifying Gas and Thermal Energy Emissions in an Active Geothermal Area: Insights From Le Biancane (Larderello Field, Italy)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Larderello‐Travale area in the northern Apennines of Italy hosts the world's oldest exploited geothermal field. Its success lies primarily in the presence of an extraordinary geothermal resource housed in a large vapor‐dominated fractured reservoir that produces superheated steam.

The Significance of Magnetic Fabrics Preserved in Hydrothermally Altered Rocks

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract Anisotropy of Magnetic Susceptibility (AMS) and Anisotropy of Magnetic Remanence (AMR) are critical petrofabric tools for investigating the evolution of volcano‐magmatic, tectonic, and surface process systems. These highly sensitive techniques can distinguish multiple magnetic fabrics within individual samples, crucial in assessing archives of

Experimental Hypervelocity Dust Impacts in Olivine—Multiscale Insights Into Microcrater Shock and Melting Effects From Coordinated SEM/TEM Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

Shortwave Infrared Microimaging Spectroscopy of the Martian Meteorites

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Until samples from the Martian surface are successfully brought to Earth, meteorites represent the only opportunity to perform laboratory analyses on Martian material. Microimaging spectroscopy of the Martian meteorite suite provides a valuable means to better understand infrared data collected remotely from the Martian surface. This rapid and

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

Journal 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.
