Arc Heat Flow and Magmatic Heat Budgets

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract We evaluate hydrothermal heat loss from 11 volcanic‐arc segments (∼6,000 km of arc length, ∼10% of the global total), motivated by the observation that much magmatic heat ultimately crosses the land surface as heated aqueous fluid. Heat loss takes place by volcanic eruption, geothermal heat conduction to the surface, fumarolic (vapor ...

Three‐Dimensional Characterization of Lateral Subsurface Flow in an Alpine Forested Hillslope on the Tibetan Plateau Using Time‐Lapse Electrical Resistivity Tomography

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Lateral subsurface flow (LSF) is a key component of rainfall‐runoff generation on alpine forested slopes, but the influence of weathered bedrock on LSF remains poorly understood due to methodological constraints in monitoring three‐dimensional flow dynamics. This study addresses this gap by proposing a standardized morphological interpretation

Transformation of Refractory Oceanic Lithospheric Mantle by Reactive Melt Infiltration: An Experimental Study on the Roles of Temperature, Melt Volume and Ascent Velocity

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Reactive melt infiltration critically modifies the physical and chemical properties of the oceanic lithospheric mantle (OLM). This process, involving melt‐rock reactions and in situ crystallization, exhibits substantial spatial and temporal variability driven by melt volume and ascent velocity.

Spectral Characterization of CO2‐H2O Ice Layering Under Controlled Mars Polar Conditions as Laboratory Analogs for Seasonal Cap Activity

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract Seasonal CO2 and H2O ice blanket the Martian polar caps, and their spectral contributions mix during seasonal evolution. Particularly in late northern winter, the spectral signature of H2O ice obscures that of CO2 ice. Using the MARVIN chamber at York University, we produced controlled analogs of layered polar ice under Mars‐like pressure (∼6 ...

On Being Receptive: Listening and Compliance on a University Campus

American Anthropologist, Volume 128, Issue 2, Page 249-258, June 2026.
ABSTRACT How should you listen when you hear about harms in interpersonal life, such as sexual harassment or anti‐Black racism? Across a range of sites on a university campus, from bystander intervention workshops to reporting systems for sex‐ and gender‐based misconduct, we spotlight the way “listening” is mobilized to address harms of various kinds ...

The Fate of Iron Formations in the Deep Mantle: Constraints From Iron Oxide Reduction Kinetics Experiments

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Dense sedimentary iron formations (IFs) subducted into the mantle during Earth's early history, may have descended to the core‐mantle boundary where they could exert strong control on its thermal and seismological properties. A key unanswered question is the extent to which IFs retain their oxidized character in the much more reducing mantle ...

High‐Pressure Elasticity of CAS Phase and Its Implications for the Fate of Subducted Anorthosite Crust

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The CAS phase (CaAl4Si2O11) is a key phase formed in subducted silica‐alumina rich crustal and sedimentary materials under the mantle transition zone conditions. In this study, its elastic properties were investigated using first‐principles calculations up to 30 GPa.
