Journal Article
Horwell, C. J., Damby, D. E., Stewart, C., Joseph, E. P., Barclay, J., Davies, B. V., …Tunstall, N. (2024). Physicochemical hazard assessment of ash and dome rock from the 2021 eruption of La Soufrière, St Vincent, for the assessment of respiratory health impacts and water contamination. Geological Society Special Publications, 539(1), https://doi.org/10.1144/sp539-2023-46

La Soufrière, St Vincent, began an extrusive eruption on 27 December 2020. The lava dome was destroyed, along with much of the pre-existing 1979 dome, in explosive eruptions from 9 to 22 April 2021. Lava domes generate crystalline silica – inhalation...

Melt diffusion-moderated crystal growth and its effect on euhedral crystal shapes (2023)
Journal Article
Mangler, M. F., Humphreys, M. C. S., Geifman, E., Iveson, A. A., Wadsworth, F. B., Brooker, R. A., …Hammond, K. (2023). Melt diffusion-moderated crystal growth and its effect on euhedral crystal shapes. Journal of Petrology, 64(8), https://doi.org/10.1093/petrology/egad054

Crystal growth is often described as either interface-controlled or diffusion-controlled. Here, we study crystal growth in an intermediate scenario where reaction rates at the crystal-melt interface are similar to the rates of diffusive transport of...

The permeability of loose magma mush (2023)
Journal Article
Bretagne, E., Wadsworth, F. B., Vasseur, J., Humphreys, M. C., Dingwell, D. B., Dobson, K. J., …Rooyakkers, S. M. (2023). The permeability of loose magma mush. Geology, 51(9), 829-832. https://doi.org/10.1130/g51133.1

Models for the evolution of magma mush zones are of fundamental importance for understanding magma storage, differentiation in the crust, and melt extraction processes that prime eruptions. These models require calculations of the permeability of the... Read More about The permeability of loose magma mush.

Variation of plagioclase shape with size in intermediate magmas: a window into incipient plagioclase crystallisation (2022)
Journal Article
Mangler, M. F., Humphreys, M. C., Wadsowrth, F. B., Iveson, A. A., & Higgins, M. D. (2022). Variation of plagioclase shape with size in intermediate magmas: a window into incipient plagioclase crystallisation. Contributions to Mineralogy and Petrology, 177(6), Article 64. https://doi.org/10.1007/s00410-022-01922-9

Volcanic rocks commonly display complex textures acquired both in the magma reservoir and during ascent to the surface. While variations in mineral compositions, sizes and number densities are routinely analysed to reconstruct pre-eruptive magmatic h...

Magma recharge patterns control eruption styles and magnitudes at Popocatépetl volcano (Mexico) (2022)
Journal Article
Mangler, M. F., Petrone, C. M., & Prytulak, J. (2022). Magma recharge patterns control eruption styles and magnitudes at Popocatépetl volcano (Mexico). Geology, 50(3), 366-370. https://doi.org/10.1130/g49365.1

Diffusion chronometry has produced petrological evidence that magma recharge in mafic to intermediate systems can trigger volcanic eruptions within weeks to months. However, less is known about longer-term recharge frequencies and durations priming m...

Critical assessment of pressure estimates in volcanic plumbing systems: The case study of Popocatépetl volcano, Mexico (2021)
Journal Article
Tommasini, S., Bindi, L., Savia, L., Mangler, M. F., Orlando, A., & Petrone, C. M. (2022). Critical assessment of pressure estimates in volcanic plumbing systems: The case study of Popocatépetl volcano, Mexico. Lithos, 408-409, Article 106540. https://doi.org/10.1016/j.lithos.2021.106540

Most geobarometers use chemical compositions of minerals and their host melt to estimate crystallization pressures. Crystal structural parameters such as cell and site volumes are not usually considered despite their known sensitivity to pressure. He...

Effusive eruptions dominate the eruptive record of many arc volcanoes and may hold crucial information about their plumbing systems, yet they are underrepresented in geochemical and petrological studies. Here, we present whole rock major and trace el... Read More about Interplinian effusive activity at Popocatepetl volcano, Mexico: new insights into evolution and dynamics of the plumbing system.
