Evolving Subduction Zone Thermal Structure Drives Extensive Forearc Mantle Wedge Hydration

open access: yesAGU Advances, Volume 5, Issue 4, August 2024.
Abstract Hydration of the subduction zone forearc mantle wedge influences the downdip distribution of seismicity, the availability of fluids for arc magmatism, and Earth's long term water cycle. Reconstructions of present‐day subduction zone thermal structures using time‐invariant geodynamic models indicate relatively minor hydration, in contrast to ...

Phase Transitions in Materials with Thermal Memory: the Case of Unequal Conductivities

open access: yes, 2009
A model for thermally induced phase transitions in materials with thermal memory was recently proposed, where the equations determining heatflow were assumed to be the same in both phases.

Dynamic calculation of heat-flow coupled mine ventilation network with introduction of air volume fluctuation factor

open access: yesMeitan xuebao
To address the issue of continuous multi-scale fluctuations in air volume due to the thermal flow within the unsteady airflow medium in the ventilation system pipe domain, which limits the accuracy of system state mapping when using a static thermal ...

Evaluation simplifiée du flux géothermique en bassin sédimentaire. Comparaison et discussion Simplified Heat-Flow Evaluation in a Sedimentary Basin: Comparison and Discussion

open access: yesOil & Gas Science and Technology, 2006
Les mesures de flux géothermiques sont rares, et cela est dû pour l'essentiel à une méthodologie lourde qui impose d'effectuer un log thermique par forage. Dans cet article, nous proposons une méthode d'évaluation de la densité de flux géothermique basée

Investigating the Lid Effect on the Generation of Ocean Island Basalts: 1. Geochemical Trends

open access: yesGeochemistry, Geophysics, Geosystems, Volume 25, Issue 6, June 2024.
Abstract Ocean island basalts (OIBs) are generated by mantle plumes, with their geochemistry controlled by a combination of source composition, temperature, and thickness of overlying lithosphere. For example, OIBs erupting onto thicker, older oceanic lithosphere are expected to exhibit signatures indicative of higher average melting pressures.

Heatflow: an interactive computer program for the analysis of heat production in gold mines

open access: yes, 2015
The cooling of deep gold mines is costly and must therefore be planned carefully. To provide a precise assessment of underground air temperatures, a computer program, HEATFLOW, has been designed.

(In-)Stability of singular equivariant solutions to the Landau-Lifshitz-Gilbert equation

open access: yes, 2013
In this paper, we use formal asymptotic arguments to understand the stability properties of equivariant solutions to the Landau-Lifshitz-Gilbert model for ferromagnets.

Evidence From Intermediate‐Depth Earthquakes of Slab‐Derived Fluids Beneath the Taupō Volcanic Zone

open access: yesJournal of Geophysical Research: Solid Earth, Volume 129, Issue 5, May 2024.
Abstract Ahi Tupua, the central section of the Taupō Volcanic Zone in the central North Island of New Zealand, encompasses Taupō and Ōkataina calderas and has been the most frequently active and productive silicic magma system worldwide during the Quaternary.
