Geothermobarometry of the 2010 Eyjafjallajökull eruption: New constraints on Icelandic magma plumbing systems [PDF]

Journal of Geophysical Research: Solid Earth, 2012
The 2010 Eyjafjallajökull eruption in Iceland produced mildly alkaline basalt that was emitted during the initial flank eruptive phase, whereas tephra predominately of benmorite composition was erupted during the second explosive phase from the summit of the volcano.

Magma residence time, ascent rate and eruptive style of the November ash-laden activity during the 2021 Tajogaite eruption (La Palma, Spain)

Volcanica
We combined compositional analyses, crystal size distributions and geothermobarometry of tephra erupted during the 2021 Tajogaite eruption (La Palma, Spain), focusing on samples collected in November 2021 associated with a period of abundant ash emission

Efficacy of Assessing Magmatic Storage Depth Using Natural Samples, Experiments and Thermodynamic Models: A Case Study From Valles Caldera, NM (USA)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Estimates of magmatic storage are typically made using mineral assemblages in natural samples, experiments and thermodynamic models (e.g., MELTS), where each method has limitations. Here, we compare each of these methods to assess their utility in estimating storage conditions for post‐collapse, two‐feldspar high‐silica rhyolites (HSRs ...

Pohorje eclogites revisited: Evidence for ultrahigh-pressure metamorphic conditions

Geologija, 2010
Kyanite eclogites from the Pohorje Mountains, Slovenia, are providing the first evidence of ultrahigh-pressureEo-Alpine metamorphism in the Eastern Alps. Polycrystalline quartz inclusions in garnet, omphacite and kyaniteare surrounded by radial fractures

The Mesozoic along-strike tectono-metamorphic segmentation of Longmen Shan (eastern Tibetan plateau) [PDF]

, 2018
The Longmen Shan belt (eastern border of the Tibetan plateau) constitutes a tectonically active region as demonstrated by the occurrence of the unexpected 2008 Mw 7.9 Wenchuan and 2013 Mw 6.6 Lushan earthquakes in the central and southern parts of the ...

Numerical Modeling Integrated With Field Observations and Analytical Data of the 2021 Cumbre Vieja Eruption Improves Understanding of Eruption Dynamics at Mafic Volcanoes

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Abrupt transitions in eruptive style are common at mafic volcanoes, possibly leading to styles that potentially damage infrastructures and threaten the surrounding communities. During the 19th September–13th December 2021 Cumbre Vieja eruption (La Palma, Canary Islands), rapid changes in eruptive style were observed, from vigorous lava ...

Magma‐Assisted Flexure of Hawaiian Lithosphere Inferred From Three‐Dimensional Models of Lithospheric Flexure Constrained by Active Source Seismic Data

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 6, June 2025.
Abstract Reprocessed and newly acquired seismic data provide new constraints on lithospheric flexure profiles beneath the Hawaiian Islands. We use these new observations and three‐dimensional numerical models of lithospheric deformation combining elasticity, brittle failure, low‐temperature plasticity (LTP) and high‐temperature creep deformation ...

Lithological structure of western Pacific lithosphere reconstructed from mantle xenoliths in a petit-spot volcano

Progress in Earth and Planetary Science, 2022
The lithospheric mantle, formed at the mid-ocean ridge as a residue of crustal production, comprises theoretically depleted peridotite, but more fertile components (e.g., lherzolite and pyroxenite) have been reported, creating an enigmatic picture of the
