A Scaling for the Permeability of Loose Magma Mush Validated Using X‐Ray Computed Tomography of Packed Confectionary in 3D and Estimation Methods From 2D Crystal Shapes. Journal of Geophysical Research: Solid Earth, 128(10), Article e2023JB026795. https://doi.org/10.1029/2023jb026795

Melt percolation through partially molten “mushy” regions of the crust underpins models for magma migration, accumulation, and processes that prime systems for eruption. Knowledge of the hydraulic properties of magma mush, specifically permeability,...

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.

Universal scaling for the permeability of random packs of overlapping and nonoverlapping particles (2022)
Journal Article
Vasseur, J., Wadsworth, F. B., Bretagne, E., & Dingwell, D. B. (2022). Universal scaling for the permeability of random packs of overlapping and nonoverlapping particles. Physical Review E, 105(4), Article L043301. https://doi.org/10.1103/physreve.105.l043301

Constraining fluid permeability in porous media is central to a wide range of theoretical, industrial, and natural processes. In this Letter, we validate a scaling for fluid permeability in random and lattice packs of spheres and show that the permea...

Quantifying Microstructural Evolution in Moving Magma (2020)
Journal Article
Dobson, K. J., Allabar, A., Bretagne, E., Coumans, J., Cassidy, M., Cimarelli, C., …Wanelik, K. (2020). Quantifying Microstructural Evolution in Moving Magma. Frontiers in Earth Science, 8, https://doi.org/10.3389/feart.2020.00287

Many of the grand challenges in volcanic and magmatic research are focused on understanding the dynamics of highly heterogeneous systems and the critical conditions that enable magmas to move or eruptions to initiate. From the formation and developme... Read More about Quantifying Microstructural Evolution in Moving Magma.
