Variable Flood Discharge Constrains Autochthonous Organic Carbon Preservation in Deltas: Insights From Physical Experiments

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Many global and regional climate models predict shifts in the frequency and magnitude of precipitation events. It is unclear how this transition will influence delta and wetland development. We address this knowledge gap via two reduced‐scale physical delta experiments: one with constant discharge and the other with variable discharge.

Clay Reimagined: Phyllosilicates as Future Membrane Technologies

Advanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Recent advancements in membrane technologies based on 2D materials have drawn attention for molecular‐scale separations owing to these materials’ tunable nanoscale interlayer properties. Phyllosilicates, natural and abundant layered clay minerals, have emerged as scalable and cost‐effective candidates.

Investigation of formation mechanism of tufa deposits by chemical breakdown of legacy paper mill sludge

The Depositional Record, Volume 12, Issue 1, February 2026.
This study reveals that legacy paper mill sludge can generate tufa deposits through calcium leaching and atmospheric CO2 interaction, acting as a carbon sink. The findings highlight its potential for low‐cost carbon sequestration and sustainable waste management.

On the Role of the Interlayer Interactions in Atomistic Simulations of Kaolinite Clay

Molecules
A systematic simulation study was performed to investigate the interlayer interactions in a 1:1 layered phyllosilicate clay, kaolinite. Atomistic simulations with classical realistic force fields (INTERFACE and ClayFF) were used to examine the influence ...

Domed‐rim microbial polygons and their preservation potential

The Depositional Record, Volume 12, Issue 1, February 2026.
Microbially induced sedimentary structures (MISS) derive through interactions between minerals and microorganisms. We define a domed‐rim MISS, morphologically distinct from abiotic mud cracks and demonstrate its potential for long‐term preservation. These structures represent promising biosignatures in ancient environments on Earth and potentially Mars.

Impact Reactivation of a Hydrothermal System in Basalt in the Vargeão Dome Impact Structure, Brazil

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract As hydrous minerals have been observed in impact craters on Mars, impact‐generated hydrothermal systems (IGHSs) have been considered as potential habitats for life on that planet. The Vargeão Dome, a 12 km wide impact structure in southern Brazil, was formed in basalts with at least two hydrothermal alteration stages.

Soil Organic Matter Stabilization by Polyvalent Cations in a Buried Alkaline Soil

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 2, February 2026.
Abstract Buried paleosols can store large quantities of organic carbon (C), much of which persists for millennia due to isolation from surface processes that promote decomposition. Subsoil organic matter (SOM) persistence is often enhanced by mineral associations and ionic conditions—particularly high clay content and polyvalent cations—that limit ...
