A Shallow‐Marine Ecosystem Before Initial Tibetan Plateau Uplift

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The uplift of the Tibetan Plateau profoundly influences global atmospheric circulation, sediment transport, and biodiversity, but its pre‐uplift marine paleoenvironment remains poorly understood. Here we report the first discovery of an in situ benthic fossil assemblage from the Puga area in central Tibet, which was deposited on a shallow ...

Significant Reduction in Ethane Emissions in the Denver‐Julesburg Basin From 2015 to 2021 From Oil and Natural Gas Operations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 17, 16 September 2026.
Abstract Top‐down studies of methane (CH4) emissions often use the average ethane‐to‐methane (C2/C1) ratio of wellhead gas in a basin to attribute emissions to thermogenic or biogenic sources. Biogenic CH4 sources (ruminants, wetlands, landfills, and other methanogenic sources) do not co‐produce ethane (C2H6); the presence of C2H6 indicates a ...

Fluid Injection Triggers Large‐Scale Slow‐Slip Activation of the Rocky Mountain Fold and Thrust Belt

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Using interferometric synthetic aperture radar (InSAR) we show that hydraulic fracturing treatments near the subsurface deformation limit of the Rocky Mountain Fold and Thrust Belt produced 12 intraplate, aseismic, slow‐slip events with magnitudes Mw ${M}_{w}$ 4.71–5.06 at 1,640–2,410 m depths.

High-resolution environmental change in the late Jurassic Kimmeridge clay formation

, 2000
Several discrete intervals of the Late Jurassic Kimmeridge Clay Formation were analyzed to assess the high-resolution environmental change, which occurs within laminated lithologies. The material was from new boreholes drilled in Dorset, southern England,

Reconnaissance study of watershed and cave sediment sources discharging from a karst spring, Iowa

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Springs discharging from karst landscapes provide sustainable flows to natural ecosystems and support productive fish hatcheries but sediment discharging from springs threatens the long‐term sustainability of hatcheries. In this study, we conducted a reconnaissance study to evaluate watershed and cave sediment sources discharging to Siewers ...

Methane Valorization Toward Carbon Neutralization: Catalytic Materials, Multiphase Interfaces, and Reactor Engineering Under Mild Conditions

Carbon Neutralization, Volume 5, Issue 5, September 2026.
The valorization of CH4 toward carbon neutralization and energy sustainability: transforming global emissions into high‐–value products via mild catalytic strategies. ABSTRACT The direct conversion of methane into value‐added chemicals under mild conditions offers a sustainable pathway to utilize this abundant hydrocarbon feedstock and mitigate ...
