Anaerobic Codigestion of Municipal Wastewater, Landfill Leachate, and Crude Glycerin: Process Stability and Methane Yield Assessment Using a Screening Design

Water Environment Research, Volume 98, Issue 2, February 2026.
Anaerobic codigestion of municipal wastewater with landfill leachate and crude glycerin can achieve near‐theoretical methane yields (0.349 L NCH4/g tCODadd). An optimal mixture of 2% leachate and 1% glycerin was identified, as higher glycerin content negatively impacted performance, highlighting the criticality of substrate balance for energy recovery.

Testing Volcano Deformation Models Against 3D Seismic Reflection Imagery of Ancient Intrusions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Magma intrusion often drives uplift of the overburden and free surface. Analytical modeling of such surface uplift at active volcanoes allows us to estimate intrusion geometries and positions, as well as volume and pressure changes; these insights have proven critical to forecasting volcanic unrest and eruptions. However, it is rarely possible

Density of Sodium Aluminosilicate Melts Along the NaAlSiO4‐NaAlSi3O8 Join at High Pressure: In‐Situ Measurements and Re‐Calibration of a Modified Hard‐Sphere Equation of State For Silicate Melts

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Silicate melts play a crucial role in planetary differentiation. The density contrast between silicate melts and the surrounding solid residue exerts a primary control on many magmatic processes. However, direct measurements of the density of silicate melts at high pressure (P) and temperature (T) conditions remain challenging, particularly ...

Sedimentary Architecture of the Stimson Formation at the Naukluft Plateau, Gale Crater, Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 2, February 2026.
Abstract Sedimentary texture, facies, and architecture can be used to reconstruct the palaeoenvironment under which sediments accumulate. On Mars, palaeoenvironmental reconstructions are used to understand ancient Martian atmospheric circulation, surface sedimentary processes, and the presence of water, to provide insight into ancient habitability and ...

Interplay Between Mechanical and Petrochemical Models on the Fluid Extraction From Subduction Zones

Journal of Metamorphic Geology, Volume 44, Issue 2, Page 85-111, February 2026.
ABSTRACT The breakdown of hydrous minerals during subduction results in a densification of the rocks, producing volume changes that can trigger fluid pressure fluctuations and hydrofracturing. These volume changes are controlled by the Clapeyron slope of the reaction and are quantified here using a macroscopic framework that integrates a zero ...
