Precipitation mechanism of anhydrite cement in lacustrine tight sandstone: Implications for fluid activity, mass transfer and pore origin of open diagenetic system in tight sandstone

The Depositional Record, Volume 12, Issue 1, February 2026.
This paper discusses a new model concerning the precipitation mechanismand significance of anhydrite cement in tight sandstone. Anhydrite cement ismainly formed by the dissolution and reprecipitation of early‐diageneticcalcite cements, feldspars and volcanic rock fragments at the mesodiageneticstage.

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

The 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 ...

Changes in Dominant Streamflow Drivers as Network‐Scale Flow Regime Shifts From Intermittent to Ephemeral Across a Multi‐Year Drought

Hydrological Processes, Volume 40, Issue 2, February 2026.
Spatial variability in surface water activation and persistence decreased with ongoing drought. The importance of landscape attributes in explaining surface water presence decreased throughout the drought. Flow activation events after several years of drought were more closely associated with precipitation event characteristics than antecedent storage ...

Prediction of formation abrasiveness under the action of a PDC bit based on the fractal dimension of a rock surface

Scientific Reports
During rock drilling, a drill bit will wear as it breaks the rock. However, there is no uniform grading standard for rock abrasiveness. To solve this problem, the wear mechanisms of a polycrystalline diamond compact (PDC) bit and the formation it is ...

Hidden Partners in Diversity: Acidobacteriota and Their Distribution in the Cape Floristic Region

MicrobiologyOpen, Volume 15, Issue 1, February 2026.
Acidobacteriota diversity and abundance investigated in nutrient‐poor fynbos soils of the Cape Floristic Region. Nanopore 16S rRNA sequencing of 26 soil samples from Jonkershoek and Kogelberg identified dominant and rare subdivisions, revealed distinct community compositions, and demonstrated correlations between subdivisions and soil properties ...

From wells to windmills: Resource redeployment and new technology investment in the energy sector

Strategic Management Journal, Volume 47, Issue 2, Page 616-642, February 2026.
Abstract Research Summary This study examines how multi‐business firms redeploy resources following an industry shock. Using the case of oil and gas firms diversified into wind power, I show that firms reduced expenditure in oil and gas—particularly on complex offshore projects—while increasing investment in wind after the 2014 oil price crash.
