Our new paper in Nature takes a critical look at what happens when you drill into a magma body. We find that by understanding that response properly, you can unwind the processes and get back to what the conditions of magma storage really were. www.nature.com/articles/s41...

Is water actually lava? It may sound quirky but there’s some surprisingly solid geoscience behind the playful thought experiment that shows just how much our definitions shape the way we see the planet. 💡 Let us know what you think: geoscientist.online/sections/vie... #geoscience #geology #scicomm

In 2017 we went to the Diamond Light Source to test if we could make obsidian by slowly cooling bubbly magma inducing resorption of the bubbles. We found that we could, so long as the cooling was very slow. www.nature.com/articles/s41...

It's amazing to me how consistent the rheology of magmatic silicate melts can be across such a wide range of compositions. One dimensionless law to describe them all up to and including the point of failure at their failure stress, which is always around 100 MPa (roughly).

As part of this paper, Katie Schofield (PhD student at Durham University) unravelled the crystallization history of this sample from the Adamello massif to show how melt fraction evolved. It's exactly that kind of mush seize-up at low melt fraction that our model is built to predict.

New paper! The last of Eloïse Bretagne's PhD papers is out! Here we generalize our models for permeability to magma mush at any melt fraction. Take a look if you want to model percolative flow of melt through a magma mush and if you want to account for crystal shape. OA: dx.doi.org/10.1029/2025...

The grind setting on a Mahlkönig represents the spacing between the burrs. Therefore grind setting is linear with the mean coffee grain radius produced by grinding. These grinds were made from two coffees from Squaremile with Gareth Jones from James Hoffmann’s team.

Our new magma mush permeability model can predict the permeability of both disequilibrium and equilibrated micro-textures, including down to very low melt fractions (porosities). This model is flexible and could be used in the future embedded in simulations of melt percolation in the crust.

We're simulating melt flow through crystallising magma mush. As the melt channels are progressively shut off, the flow is localised in the tight connected spaces that remain.
