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!

Prepping for #EGU25 as one of the artists in residence! Taking the canvas off the frame so I can travel with it (surprisingly worked out ok) 🎨🙏 #EGUart

After a [very] long hiatus I have a #geoart themed print available in my new shop! So excited to be getting back into this 🌍🫶 You can find the print here annabellefoster.com/shop !

Diagnosing inflammatory diseases early is SO important and determines long-term outcomes/symptoms (something I’ve learnt from lived experience). It’s v exciting to read science that’s advancing this 🙌

I’m SO excited and grateful to be one of the artists in residence at @eurogeosciences.bsky.social this year! Looking forward to lots of discussions about #geoart 🌋🦖 You can read more about it here t.co/hNC8fnU13N and introduce yourself to Liliane, another artist in residence!

For #thinsectionthursday, an artistic treat: One of my students, Augusta Weaver, prepared 12 paintings of rocks under microscope for her Studio Art minor project. To say I'm proud is an understatement 🤩 Augusta took my Earth Materials class last Fall, and she fell in love with thin sections

I am reaching out to the #geoscience community - I need help. My MSc thesis was curtailed due to being unable to even access the building @ my previous university♿️ they provided no alternative. They’ve taken no responsibility for this #discrimination after I submitted an appeal.

Work in review: here's a result from @annabellef.bsky.social's PhD, where she measured the sintering rate of obsidian with some supersaturated dissolved water. She modelled the diffusive water loss during sintering, to arrive at an overall sintering curve that describes the data very well.

Sad outcome. Deep ocean drilling has changed our fundamental understanding of geology, geophysics, oceanography, marine biology, as well as climate and fundamental life processes...the list of impacts for many decades is enormous #JoidesResolution #JR #Oceanography www.science.org/content/arti...

Scientists and/or nerds: what’s a geologic or natural event we don’t talk about enough, in your opinion? Mine is the Zanclean flood, ie “the straight of Gibraltar went ‘oop’ and the Atlantic rushed in fast enough to form the Mediterranean Sea in <2 years”

I took one of favourite illustrations from my upcoming book and recreated it using coloured card. Yes, it took quite a while. No, I mostly don’t regret it 🤩 #SciArt

New study from @fabianwadsworth.bsky.social and team examines how crystal-rich magmas deform: a combination of viscous flow and fracture on different spatial scales. Especially relevant to lava dome emplacement. Bravo!

In this new paper we determined the rheology of the magma that was intercepted by the 2009 IDDP-1 borehole at Krafla, Iceland. We also worked out how quickly it cooling during the drilling. doi.org/10.1016/j.jv...

For #ThinSectionThursday, bipyramidal quartz and alkali feldspar phenocrysts in flow banded felsite from the ring complex at Slieve Gullion, County Down; the eroded guts of a volcano active about 60 million years ago. #thinsection #geology #volcano #petrology #ireland #northernireland

Been panicking for months on what to get my brother for his 30th birthday and this is what I settled on 🎨
