Calcareous Benthic Foraminifera Under Ocean Alkalinity Enhancement: Synthesis, Knowledge Gaps, and Future Research Agenda

Earth's Future, Volume 14, Issue 9, September 2026.
Abstract Limiting global warming to 1.5°C will require carbon dioxide removal, and Ocean Alkalinity Enhancement (OAE) is increasingly being explored as a marine carbon dioxide removal pathway. However, benthic biological responses remain much less constrained than water‐column processes and planktonic responses, even though calcareous benthic ...

The Distinction Between Sn‐Mineralized and Sn‐Barren Granites in Sn Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Tin mineralization is commonly associated with highly evolved granites. However, not all highly evolved granitic rocks are mineralized with Sn. Comparative studies of Sn‐fertile and Sn‐barren granites can deepen our understanding of the key processes that lead to Sn enrichment in magmatic‐hydrothermal systems.

Microscale Hyperspectral Mapping of a Kilometer of Mantle Rocks: Insights Into Low‐Temperature Serpentinization Systems From the Oman Drilling Program Cores

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Characterizing products of water‐rock interactions in low‐temperature serpentinization of ultramafic rock is key to reconstructing fluid alteration histories of the crust and identifying subsurface habitable environments. We analyzed terrestrial peridotites from the Samail ophiolite using visible to near‐infrared (VNIR‐SWIR) microimaging ...

Experimental weathering rates of aluminium-silicates

, 2013
L'altération chimique des roches primaires et des minéraux dans les systèmes naturels a un impact majeur sur la formation des sols et leur composition. L'altération chimique est largement pilotée par la dissolution des minéraux. Les éléments chimiques libérés dans les eaux souterraines par la dissolution des minéraux réagissent facilement pour former ...

Silicate Weathering and Diagenetic Reaction Balances in Deltaic Muds

Reactions between terrigenous sediments, marine-biogenic substances and seawater modulate multiple biogeochemical cycles, but the dynamics and factors governing these reactions are poorly constrained.

Formation and Alteration of Magnesite Nodules From Kunwarara, Queensland, Australia, as an Analog to Mg‐Carbonate Formation on Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Magnesite (MgCO3) is a magnesium (Mg) carbonate mineral that records the aqueous environmental conditions of its formation. On Earth, magnesite forms in metamorphic, diagenetic or pedogenic environments, and distinguishing between these environments is critical for understanding the fluid chemistry during magnesite precipitation. Mg carbonates
