Ferromagnesian Clay Diversity Across Mars' Crustal Dichotomy: A Window Into Early Aqueous Environments

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.
Abstract Extensive research over the past two decades has shown that early Mars likely had a warmer, wetter climate with widespread water activity. Ferromagnesian (Fe,Mg‐rich) clay deposits are compelling markers of these ancient environments, helping reconstruct Mars' hydrologic evolution, assess past habitability, and guide future exploration.

Adsorptive Elimination of Heavy Metal Ions From Wastewater Utilizing Natural and Synthetic Zeolites: Mechanistic Analysis, Modification Techniques, and Performance Assessment

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Heavy metal contamination in wastewater remains a critical environmental challenge due to the persistence and toxicity of metal ions such as Pb2+, Cd2+, Cr3+/Cr6+, Cu2+, Ni2+, and Zn2+. Although conventional treatment technologies can achieve high removal efficiencies, their practical application is often limited by high operational costs, energy ...

Palagonitization of Volcanic Rocks in Polar Climates: The Case of Deception Island (Antarctica)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract A detailed study of palagonitization in rocks from Deception Island—one of Antarctica's most active volcanoes—has been performed to advance our understanding of this alteration process. A detailed petrographic (optical and SEM), mineralogical (XRD), and mineral and glass spot geochemistry (EDS and EMP) characterization has been conducted on ...

Microbial Community Composition and Function in Jiangsu Oil Reservoir Cores, China

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Shale oil reservoirs meet the basic requirements for microbial growth. Microorganisms, crude oil and water are distributed within the pore spaces of the reservoir formation. In situ microorganisms utilise crude oil for growth and reproduction. ABSTRACT Shale oil reservoirs are typically characterised by elevated temperatures, confined spaces and ...
