OTD in 1988 Steve Archibald's iconic clincher for @thehibees.bsky.social against Hearts. First Edinburgh derby match I had missed in years. I was sat in A&E having just ruptured two knee ligaments playing in goal for @edinburgh-uni.bsky.social AFC. #GGTTH 💚⚽

Rosalind Franklin died at 37 of ovarian cancer attributed to radiation exposure from the methods she & her assistant used to photograph a cross-section of the DNA double helix. Meanwhile, Watson won a Nobel off that work & survived to the ripe old age of 97 by simply: stealing those notes!

I remain absolutely confused that people *ever* thought screwing with the abyssal sea floor would "get better" after mining.

Using nitrogen isotopes in seaweed over a 2-year period we have been able to pinpoint the source of poor water quality in Scarborough - further research is required in Scalby Beck to pinpoint the sources of human sewage and agricultural manure www.durham.ac.uk/news-events/...

If you are ever close by then do this walk - both the scenery and geology are glorious. It's where we take @durhamearthsci.bsky.social freshers for their first fieldtrip and is always a stunning day out (even in this year's downpour!)

🚨 new paper and proud supervisor moment 🚨 A former 4th year undergraduate research project student has published her work: www.jvolcanica.org/ojs/index.ph... Social sensing the 2018 Kīlauea Volcanic eruption through community Facebook use #volcanology #risk #hazards 🧪⚒️🌋

Splendid timing for my crust/mantle evolution lecture on Monday. 😃 Dreadful timing as that lecture is already five minutes too long 😩🧪⚒️

📢 PhD opportunity at Newcastle University! 👉"Reconstructing past ice-sheet retreat and ice-ocean interactions from marine sediment cores". This project will use new marine sediment cores to constrain the timing and drivers of past ice-sheet retreat. More details: iapetus.ac.uk/studentships...

Stunning TV this was

Well this will cause a bit of a stink ... 🧪⚒️🌋🌍 www.geochemicalperspectivesletters.org/article2539/...

Happy World Lemur Day!

If you wanna look on my works, You’re gonna look with despair, Make it last for ever, Now two trunkless ends, With visage toppled over, The sculptors did achieve, The countenance of Ozy Saying “l’m the King of Kings” I’ll tell you where I went, Where I winnow winnow went … Ozymandias Spice

Bought most of my food and sent postcards home from the Ferry Stores when I did my undergraduate mapping dissertation in Ardnamurchan (many moons ago). This is very sad news. ⚒️

To identify birefringence use SEQUENCES of interference colours. Olivine phenocrysts in this Rio Grande alkali basalt demonstrate this for 4th order green. Magentas near top of orders are particularly useful for this. 🧪⚒️🌋 🧵1/2 #ThinSectionThursday

Imaginative ways to say "I doubt that very much" #37. PJ Wyllie, 1984. 🧪⚒️🌋 #ScienceWriting #scicomm

Etendeka alkaline dolerite for #ThinSectionThursday. XPL view showing vibrant, equant olivine crystals (mid-right), and classic ophitic texture of plagioclase laths (black and white) surrounded by very large clinopyroxenes. 🧪⚒️

Holy ground for geologists! Holyrood Park in Edinburgh. Showing our University of Edinburgh undergrad students where the discipline of Earth sciences began: When James Hutton noticed this crystalline rock sandwiched between burnt sandstone layers, and realized the Earth was old!

If you’re attending #EGU26 and are working on caldera volcanism consider submitting an abstract to GMPV7.5! Looking forward to convening this session! 🌋

The Stranglers at City Hall Newcastle 21 October 2025 playing Duchess, first of their song I ever heard (many moons ago). Brilliant set. 🖤🐀

Define your music taste in eight artists: The Stranglers Rush Deep Purple Ronnie James Dio Martyn Bennett Ian Dury & The Blockheads R.E.M. Fish (Derek Dick)

These are wise, wise words ... for students of science, engineering, arts and humanities, plumbing etc. ... 🧪

I have negligible interest in baseball but having lived and worked in Canada for a couple year (ages ago) I'm delighted for the Blue Jays. (As will be Geddy Lee!)

🌋We have a 2.5-years long fully funded Postdoctoral position opened at UoEdinburgh to study volcanic plumes with 3D modelling. Spread the word! elxw.fa.em3.oraclecloud.com/hcmUI/Candid...

But … but … my son loves The Stranglers and Rush

Here's the live webcam feed from the US Geological Survey Hawaiian Volcano Observatory. It's well worth keeping an eye on. 🧪⚒️🌋 www.youtube.com/watch?v=tk0t...

Interesting isotope tracing, though admit at first glance I thought we were getting a butcher’s chart of different cuts on a winged lion! 🧪

Come do an exciting new PhD project with fieldwork in the Caribbean and S Pacific working on understanding what happens when powerful lahars enter the ocean - with me, @isobelyeo.bsky.social at @noc.ac.uk www.findaphd.com/phds/project...

Another exciting PhD opportunity with @isobelyeo.bsky.social, me and others on Mapping Hydrothermal Fluid Flow in Earth’s Most Explosive Volcanoes… www.findaphd.com/phds/project...

Arc lithosphere tension. It's important folks. 🧪⚒️🌋 🧵1/3

Quartz, plagioclase, K-feldspar

True @callanbentley.bsky.social for modern usage of porphyry. BUT, the origin of the word porphyry is from an Ancient Greek term for purple (particularly by the Romans). Quite possible this frog might have been called porphyry before that word acquired its current usage. 🧪⚒️🌋

Well that’s just marvellous

Oh buoy!

Spectacular concentric zoning and twinning of large titanaugite in essexite (nepheline monzogabbro) from Lennoxtown, Scotland. Plagioclase inclusions within the phenocryst align with zoning just as proximal groundmass plagioclase align with its edge. #ThinSectionThursday 🧪⚒️

Fantastic final day of Level 2 geological fieldwork in Assynt 🔨🌱 #FieldWork

Sorry, got to disagree. "It was the day my grandmother exploded" opening The Crow Road by Iain Banks is the greatest first line of a novel. 📖

Fascinating interaction of magmatism and tectonics in the Aegean "arc".

We are advertising for a 3-year "Senior Research Associate in Volcanic Petrology and Stratigraphy". Part of a Leverhulme-funded interdisciplinary research grant "Volcanic Histories", focused on research in the Eastern Caribbean. Closing: October 15th www.bristol.ac.uk/jobs/find/de...

Sodalite-rich portion of lajuvrite from Ilimaussaq, Greenland. Large, euhedral (isometric) sodalite crystals are black in XPL. Interstitial aegirine augite shows green masking over strong interference colours. Collected by the late Henry Emeleus #ThinSectionThursday 🧪⚒️
