Linking palaeo‐wildfire to depositional environmental and ecological dynamics of an Early–Middle Pennsylvanian fluvial‐tidal transition zone—Palynology and pyrolysis evidence

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...

Optimizing Soil Properties Through Hydrogel and Sawdust Combinations for Better Plant Growth

open access: yesJournal of Plant Nutrition and Soil Science, Volume 189, Issue 1, Page 168-178, February 2026.
This graphical abstract illustrates the effects of various soil amendments on poplar cutting vitality under drought conditions, as observed using X‐ray computed tomography (CT). It compares soil alone, soil with sawdust, soil with hydrogel, and their combination, highlighting differences in internal structure, water retention, and root development.

Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 2, Page 343-359, February 2026.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Stress and Rock Failure Near Salt Bodies: Insights From Field Observations, Kinematic Modeling, and Mechanical Analysis Near Arches National Park, Paradox Basin, Utah

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Salt's inherent weakness and capacity for ductile deformation create significant mechanical contrasts that locally perturb the stress field in surrounding rocks, often leading to deviations from regional tectonic stresses. Variations in local stress are a critical factor for wellbore stability, seal integrity, and fluid flow in subsurface ...

Anthropogenically Stimulated Carbonate Dissolution in the Global Shelf Seafloor Is Potentially an Important and Fast Climate Feedback

open access: yesAGU Advances, Volume 7, Issue 1, February 2026.
Abstract Carbonate mineral production and dissolution regulate atmospheric carbon dioxide (CO2) concentrations via modulation of the ocean alkalinity content. The anthropogenic rise in atmospheric CO2 reduces calcification rates and enhances calcium carbonate dissolution, which increases ocean alkalinity, counteracts acidification, and stimulates ocean

The Influence of Elevated Temperature on Time‐Dependent Compaction Creep in Bleursville Sandstone

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The inelastic compaction of sandstone in the upper crust typically occurs at depths where temperatures range from approximately 50°C $50{}^{\circ}\mathrm{C}$ to 150°C $150{}^{\circ}\mathrm{C}$. Previous experimental studies have shown that even this modest temperature increase can reduce the yield stress required to initiate inelastic ...
