Active Hydrothermal Hydrogen Emissions in Continental Collision Settings: Insights From the Southeastern Tibetan Plateau

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Natural hydrogen (H2) is a promising clean energy resource and a significant component of geothermal gases, yet its origins and release mechanisms remain poorly constrained. Here, we present geochemical and isotopic data (CO2, N2, Ar, H2, He, CH4, 3He/4He, δ13C‐CO2, and δ13C‐CH4) for hydrothermal gases from the Changning–Menglian suture (CMS),

Thermodynamic Modeling of Lithium Enrichment During Partial Melting: The Importance of Partition Coefficients

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Predicting the partial melting conditions that generate Li‐rich peraluminous melts is of major economic and societal importance. However, existing models disagree on the optimal conditions (e.g., pressure, temperature, protolith) and, consequently, on targets for exploration.

The Magnetic Mineralogy of Carbonaceous Chondrites: A Microscopy and Machine Learning Study of Meteorite WIS 91600

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract A central challenge in the paleomagnetic study of meteorites is to characterize their diverse remanence carriers. Here, we develop a machine‐learning assisted workflow that combines multi‐scale (mm to nm) and multi‐dimensional (2D‐3D) microscopy to build a comprehensive picture of ferromagnetic mineralogy in the C2 ungrouped carbonaceous ...

High‐Resolution Anisian Marine Perturbation by Volcanism in the Eastern Paleo‐Tethys

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Following the end‐Permian mass extinction, the Middle Triassic Anisian Stage was still characterized by environmental perturbations that hindered biological flourishing, yet it remains uncertain whether these persistent Tethyan disturbances were coupled with the closure of the Paleo‐Tethys Ocean.

Emergent Dynamics From a Position‐Based Calving Function and the Limits of a Rate‐Based Calving Function

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 7, July 2026.
Abstract A wide range of functions are currently available for simulating the calving of marine‐terminating glaciers, but there is no consensus on the best approach to represent the calving process in glacier and ice‐sheet models. Current assessments of calving functions are often crudely done by fitting functions to observed changes in terminus ...
