Great time last month at Sandfell in Iceland discovering new aspects of how magma moves in the Earth’s shallow crust. Thanks to Hugh and Ed for joining. And amazing to find the Fish Factory arts centre, the creative centre of Stöðvarfjörður!

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.

The first few days of Melts Glasses Magmas short course taught. Excited to have covered glass and melt structure and properties, up to and including brittle unrelaxed melt rupture due to viscoelasticity.

Tell me you’re working on bubble growth in magmas without telling me you’re working on bubble growth in magmas.

Go chat with @alicerpaine.bsky.social about our work comparing plumes in moderately large explosive eruptions with those rare and exceptional magnitude 8 events.

I remain obsessed by sintering processes. Here’s Julia talking about sintering of crystal-bearing granular materials with implications for silicic eruptions.

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.

Wonderful sunny visit to Lancaster with @annathrl.bsky.social to visit @htuffen.bsky.social! What a delight to see sintering textures from lava samples and to ponder new research questions with treasured collaborator, Hugh!

Another visit to the local café with @annathrl.bsky.social and her rocks. This time it’s chunks of the Arico ignimbrite from Tenerife that capture a gradational transition from poorly to densely welded.

When will volcanic ash particles stick and when will they bounce? We ask this question in the context of ash particles moving through the hot components of a commerical jet engine in flight.

Sintering of volcanic ash often occurs over similar timescales to degassing of volatiles by diffusive loss from the particles. These two processes are coupled, and so our full models for viscous sintering have to account for both. Forthcoming work from @geologytalk.bsky.social, myself, and others!
