The scientific investigation of magma fragmentation and the development of experiments to
constrain and quantify its mechanisms, dynamics, efficiency and products was ushered in …

Explosive or effusive style of volcanic eruption determined by magma storage conditions

RG Popa, O Bachmann, C Huber - Nature Geoscience, 2021‏ - nature.com
Most volcanoes erupt both effusively and explosively, with explosive behaviour being
responsible for most human fatalities. Eruption style is thought to be strongly controlled by …

Direct observation of degassing during decompression of basaltic magma

B Bonechi, M Polacci, F Arzilli, G La Spina… - Science …, 2024‏ - science.org
Transitions in eruptive style during volcanic eruptions strongly depend on how easily gas
and magma decouple during ascent. Stronger gas-melt coupling favors highly explosive …

[HTML][HTML] A universal model for the permeability of sintered materials

FB Wadsworth, J Vasseur, MJ Heap, L Carbillet… - Acta Materialia, 2023‏ - Elsevier
Sintered materials are used as permeable filters and flow controllers, for which a validated
and general model of porosity and permeability is required. Here, we prepare samples built …

Degassing and gas percolation in basaltic magmas

M Colombier, J Vasseur, BF Houghton… - Earth and Planetary …, 2021‏ - Elsevier
Due to their generally low eruptive melt viscosities and concomitant high diffusivities of
volatiles, basaltic magmas degas relatively efficiently. This relative efficiency, combined with …

Evaluating the role of titanomagnetite in bubble nucleation: novel applications of low temperature magnetic analysis and textural characterization of rhyolite pumice …

KN McCartney, JE Hammer, T Shea… - Geochemistry …, 2024‏ - Wiley Online Library
Nucleation of H2O vapor bubbles in magma requires surpassing a chemical supersaturation
threshold via decompression. The threshold is minimized in the presence of a nucleation …

Magma fragmentation: a perspective on emerging topics and future directions

TJ Jones, KV Cashman, EJ Liu, AC Rust… - Bulletin of volcanology, 2022‏ - Springer
The breaking apart of magma into fragments is intimately related to the eruptive style and
thus the nature and footprint of volcanic hazards. The size and shape distributions of the …

[HTML][HTML] The roles of microlites and phenocrysts during degassing of silicic magma

F Caceres, B Scheu, M Colombier, KU Hess… - Earth and Planetary …, 2022‏ - Elsevier
Silicic magmas span a wide range of eruptive styles between explosive and effusive, and
transitions between these styles are commonplace. Yet the triggers of switches in eruptive …
