Pallasites are so often shown cut and polished - still beautiful in their raw form though. 😍🧪⚒️

Pallasite: One of the most significant meteorites in this Museum's collection is a 1.7kg mass of the Krasnojarsk meteorite which was found in 1772. Found in Krasnojarsk, Russia, the meteorite is composed of glassy green olivine crystals embedded in Fe-Ni alloy. Unique oumnh.ox.ac.uk/learn-meteor...

A year or two ago, an AI-boosting petro-bro—a geologist if memory serves—suggested on a different platform that the entire USGS core facility should be shuttered because anything of value had been digitized and maintaining physical samples was a waste of money. He couldn't have been more wrong! ⚒️

Le Cagle@lecagle.bsky.social · 2w ago

I cannot emphasize enough of the importance of this point: the physical archive is not a digital file. And crucially, it CANNOT be a digital file. Doing research with physical samples from ecological collections requires physically analyzing them. You can't just take photos and call it a day.

The Physical Archive Is Not a Digital File Hubbard Brook Experimental Forest in New Hampshire was among the sites under review during the Forest Service restructuring but has since received a public reprieve. The future of Bartlett Experimental Forest, also in New Hampshire, remains unresolved. The governance problem, however, extends beyond either site. Hubbard Brook’s physical archive holds more than 60,000 barcoded and cataloged samples: water, soils, plant material, and physical cores spanning 7 decades of continuous collection and stored under active environmental controls in a dedicated building on site. These samples cannot be digitized. They cannot be migrated to a remote server, backed up to cloud storage, or emailed to a university partner. The samples require a functioning building, active temperature management, and a named human steward responsible for their integrity.

Durham Earth Sciences postdoc Poulami Roy @poulamiroy.bsky.social is convening an #AGU26 session on Earth's Deep Mantle! If your research spans seismology, geodynamics, mineral physics, geochemistry or planetary science, we'd love to see your abstract. 5 Aug 🔗 agu.confex.com/agu/agu26/pr...

Earth’s Heterogeneous Mantle: Multidisciplinary Perspectives on Deep Earth Dynamics and Planetary Evolution

Earth's mantle is far from a uniform reservoir; it is a complex archive of our planet's formation, differentiation, and long-term evolution. From the lithosphere down to the core-mantle boundary, mant...

Happy birthday to brilliant trailblazing US #geologist & prof Florence Bascom (1862-1945) 👩🏼‍🔬🐡🧪⚒️ #histsci who championed women’s education, & used polarizing microscopes for detailed petrographic analysis to show that rocks previously identified as sedimentary were in fact metamorphosed volcanic 🧵

My linocut portrait of geologist Florence Bascom as a young woman from neck up, in blue, looking at the viewer with her curly hair pulled back wearing a blouse with large lace collar on green vinyl. Behind her are two geological cross-sections with layers carved with different patterns to indicate different rock materials in black. Below on either side are two circular diagrams: these are thin sections of rhyolite printed in pale beige, brown, and black.

Fascinating. Shout out to the spirit of Stuart Boyd (with the equal oldest citation from this paper) who was a pioneer investigating nitrogen in high temp rocks and the solid Earth. ⚒️🧪🌋🌍

Howard Lee@hlee.bsky.social · 4w ago

🤯 Nitrogen levels in *granites* reveal strong burial of organic matter in the proterozoic eon, in line with oxygen rise. The nitrogen in the granites originated from organic matter in the sediments that melted to form the granites. ⚒️🧪 www.sciencedirect.com/science/arti...

'Our Inquiry found that white working class parents are more likely than others to say they want their children to have a better education than they had themselves: 94 per cent say this, compared with 91 per cent of all parents.' 1/3

Higher education needs to earn back the trust of white working class families

The independent inquiry into white working class educational outcomes found a lack of trust in higher education, not in aspiration. Anne-Marie Canning explains
