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 ...

Volcanic geology of the easternmost sector of the Trans-Mexican Volcanic Belt, Mexico

Journal of Maps, 2021
This work presents the volcanic geology of the easternmost sector of the Trans-Mexican Volcanic Belt, including the Serdán-Oriental basin and Cofre de Perote-Citlaltépetl volcanic range, two contrasting Quaternary volcanic fields.

Non‐Perennial, Yet Predictable: Hierarchical Stream Activation Enables the Prediction of Channel Network Dynamics in Sporadically Monitored Catchments

Water Resources Research, Volume 62, Issue 6, June 2026.
Abstract Predicting the dynamics of non‐perennial river networks is essential for hydrological modeling and water resource management. Yet, long‐term monitoring campaigns remains logistically challenging, particularly in remote and poorly accessible regions.

What can lithics tell us about hominin technology's ‘primordial soup’? An origin of stone knapping via the emulation of Mother Nature

Archaeometry, Volume 68, Issue S3, Page S8-S30, June 2026.
Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)

Capillary water absorption characteristics of some Cappadocian ignimbrites and the role of capillarity on their deterioration

, 2019
Cappadocia stands out as one of the most important regions in Turkey for its natural, historical, and cultural heritages. The region is under the influence of wetting and drying and freezing and thawing weathering processes, which are largely ...

Plant species richness response to atmospheric nitrogen deposition across bedrock types in the United States and Czechia

Ecosphere, Volume 17, Issue 5, May 2026.
Abstract Atmospheric nitrogen (N) deposition leads to many changes in terrestrial and aquatic ecosystems, affecting ecosystem processes and species composition. Terrestrial vegetation often shifts from being N‐limited to light‐limited and becomes dominated by a few fast‐growing strong competitors and generalist species.
