Antarctic Intermediate Water Variability in the South Atlantic Over the Last 600,000 years

Paleoceanography and Paleoclimatology, Volume 40, Issue 12, December 2025.
Abstract Despite its importance as a key component of the Atlantic Meridional Overturning Circulation, the long‐term variability of Antarctic Intermediate Water (AAIW) remains poorly constrained due to the lack of adequate proxy records. To address this, we present the longest reconstruction of AAIW variability in the South Atlantic using authigenic ...

Oxychlorine Species on Mars: A Review

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Oxychlorine species (mainly perchlorate and chlorate) have been identified at multiple locations on the surface of Mars by both orbiter and in situ rovers. They have also been found in martian meteorites. Cl‐isotopes in meteoritic minerals suggest that an oxychlorine cycle has been operating on the martian surface for the last ∼4 billion years.

Pułtusk H5 Chondrite—A Compilation of Chemical, Physical, and Thermophysical Data

Geosciences
The Pułtusk meteorite, classified as an H5 ordinary chondrite, is one of the best documented Polish falls, yet some important data on its physical and thermophysical properties remain limited.

Restoring the Missing Late Cretaceous Arc of Iran

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Persistent arc magmatism archives fluid transport and mantle partial melting in subduction zones. However, arc magmatism often exhibits different magmatic records along the strike, as seen in the Tethyan orogenic belt. During Neo‐Tethys subduction under Iran, there was pulsed arc magmatism with Middle Jurassic and Eocene magmatic flare‐ups ...

Evolution of Terrestrial Planetary Bodies and Implications for Habitability

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract The terrestrial planetary bodies of our solar system—Mercury, Venus, Earth, and Mars—share a common origin through nebular accretion and early magma ocean differentiation, yet they diverged significantly in geological evolution, tectonic regimes, and habitability.

Comparison of Two Methods for Determination of Rhenium and Platinum‐Group Elements in Meteorites Using On‐Line and Off‐Line Matrix Separation Modes

Geostandards and Geoanalytical Research, Volume 49, Issue 4, Page 737-750, December 2025.
Key Points PEEK tubing has been observed to adsorb Pd and Pt ions, resulting in significantly reduced recoveries of Pd and Pt elements. HPA‐S provides a more effective dissolution for meteorite samples than Carius tube digestion, resulting in higher mass fractions for PGE.
