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 ...

VolcanicaWe present a petrologic study of the post-collapse rhyolites from Valles Caldera (New Mexico, USA) to evaluate changes in magmatic storage conditions following the eruption of the Upper Bandelier Tuff (UBT). We assess likely phenocrysts through textures,

, 2020 . Residual pressure can be preserved in mineral inclusions, e.g. quartz-in-garnet, after exhumation due to differential expansion between inclusion and host crystals.

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract Volcano monitoring requires identifying and distinguishing physico‐chemical processes at various depths within magma plumbing systems and their links to volcanic activity. Long‐term monitoring of deep magma reservoirs, extending down to tens of kilometers, is crucial even though signals from these depths are often altered or attenuated before ...

Elastic-thermobarometry: methods and applications to ultrahigh pressure metamorphic rocks
Plinius, 2020 Ultra-High Pressure (UHP) metamorphic rocks represent the evidence we have for the detailed reconstruction of tectonic processes, which are the source of major natural hazards like deep-focus earthquakes and volcanic eruptions. Mineral inclusions are often the only proof of ultrahigh pressure metamorphism and their study provides insights into the ...

Journal of Economic Geology, 2020 Introduction Thermobarometric models based on the chemical equilibrium among coexisting mineral-mineral or mineral-melts pairs are useful tools widely used to estimate the P-T path and chemical evolution during igneous processes. The high sensitivity of

Earth-Science Reviews, 2020 Arclogites, or clinopyroxene-, garnet-, amphibole-, and Fe Ti oxide-bearing cumulates and restites (collectively representing residues) to andesitic continental arc magmas, are reviewed here and in a companion paper ( Ducea et al., 2020 ).

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 3, March 2026.Abstract The southwestern United States hosts well‐documented and dramatic variations in topography, seismicity, heat flow, magmatism, and seismic velocity structure. This region offers opportunities to investigate how processes such as temperature and partial melt are related to the Lithosphere‐Asthenosphere Boundary (LAB), and how they ultimately ...

Tectonics, Volume 45, Issue 3, March 2026.Abstract The strength of the intracontinental lower crust exerts a primary control on regional‐scale deformation during continent‐continent collision. Because of the nominally anhydrous nature of much of the intracontinental lower crust, it is generally considered to be more viscous than lower crust in hydrated tectonic margins.

Prograde garnet growth along complex P-T-t paths: results from numerical experiments on polyphase garnet from the Wölz Complex (Austroalpine basement) [PDF]
, 2018 Garnet in metapelites from the Wölz Complex of the Austroalpine crystalline basement east of the Tauern Window characteristically consists of two growth phases, which preserve a comprehensive record of the geothermal history during polymetamorphism. From
