Nice work!

🧪⚒️Just posted Keith Klepeis on how plutons form. He identified conduits, feeder dikes, and mushroom-shaped sheets that form as magma rises from the base of the crust to the upper crust. A tilted batholith in NZ provided him with a rare continuous exposure of 20 km of crustal section. #geology

Well reasoned and new information - “Rosalind Franklin has been reduced to the “wronged heroine” of the double helix. She deserves to be remembered not as the victim of the double helix, but as an equal contributor to the solution of the structure.” www.nature.com/articles/d41...

It’s #RadonAwarenessWeek. The UK Health Security Agency (UKSHA) recommends that radon levels should be reduced in homes where the annual averages is at or above 200 becquerels per cubic metre.

"Geologists are very pleasant companions, especially for geologists. It’s their art, to stop at every stone, and carry out an investigation at every layer of Earth" Swiss author Rodolphe Toepffer (1799-1846)

Researchers analysing data from Cassini's fly-by of Saturn’s moon, Enceladus, report that ice grains from its plume contain a variety of organic compounds, indicating complex subsurface chemistry. The findings are described in Nature Astronomy. go.nature.com/47j3pSj 🧪 🔭

🧪🌋⚒️No current US federal funding (thanks, shutdown), but the cameras are still rolling!🔥Huge gratitude for #USGS_HVO keeping the live feed up: Early morning spatter & glowing surface flows today from #Kilauea’s Episode 35 in Halemaʻumaʻu crater are putting on a show. Catch it on the V1 & V3 cams.

It is Earth Science Week. I don't regard myself as an artist but I do like the intersection or art and (geo)science.. Here is a contribution I made to the Consilience Journal that might inspire a few artists and a celebration of Earth Science. www.consilience-journal.com/conciliarte-... #sciart 🧪

🧪It's #fossilfriday and I feel fine! Here's one of my favourite 'almost' fossils, from the flood plain of the famous Snowy River Victoria, Aust. Did they make it? Unlikely. Are they are good example of process in action, absolutely. Ditto mud cracks & younging indicator. #geoscience #earthscience

The wet tropical rainforests of Queensland are now a carbon source because CO₂ emitted from trees dying and decaying outstripped the CO₂ taken up by trees growing. 😕

I put this to the test with Copilot and yeah, I think it's fair to say that it struggled with the structure of caffeine

Australia’s only shrew has been declared extinct. Australia leads the world in mammal extinctions and ranks second for loss of biodiversity. We need better funding for conservation action and stronger environmental laws to uphold our international commitments to prevent further extinctions 🧪

Thin section images of glauconitic pellet sand dredged from about 300 m on Chatham Rise, an elongate marine platform extending 1400 km east of South I. NZ. It is underlain by continental crust - a submerged part of Zelandia continent. Includes barnacles, foraminifera & echinoderm plates, spines. ⚒️🧪🌊

When is a fossil not a fossil? When it's actually a very cool, doubly pseudomorphed, mineral with a very important palaeoclimate message built-in despite having a plant based common name. #FossilFriday #EarthScience #geoscience 🧪

Hmmmm. Sausages.

🧪⚒️I just posted an episode on the orogenies that shaped central Europe: the Cadomian and the Variscan. The former took place on the northern margin of Gondwana, rifting north later to dock to Europe. The latter marked the final assembly of Pangea. It's complex, but I hope you enjoy it! #geology

A nice sunny spring morning in the garden.

A paper in Nature Communications identifies 85 previously undocumented lakes beneath the Antarctic Ice Sheet. These subglacial lakes fill and drain with a variety of patterns, revealing interconnected hydrological pathways channeling large volumes of water under the ice sheet. ⚒️ 🧪

New co-author paper out today in @pnas.org led by the fantastic Dr. Lubna Shawar! Lubna breathes new life into the sponge sterol hypothesis with her meticulous organic geochemistry, and the ID of two new sponge-derived C31 Steranes in ~600 Myr rocks. Check it out! 🧪⚒️ www.pnas.org/doi/10.1073/...

Not Friday here yet but might be busy so here is my contribution: Isograptids from Victoria, Australia. One might even be Isograptus victoriae! Ordovician black slate, from one of the best graptolite stratigraphies in the world 😀 #FossilFriday #EarthScience #geoscience 🧪⛏️

🧪Thinking about restarting a print-on-demand store for nerdy geoscience graphics to keep my mind busy while I'm out of action for extended medical treatment. Not so much art as quirky graphics. What objects would be most popular for xmas stockings? Mousepads/Playing cards/etc? #SciArt #geoscience

Not quite Friday yet but will be offline. Here is an internal cast of a brachiopod cut open to reveal the nature of the fill but it reveals something else. Can you see what it is?

Out today in @commsearth.nature.com from some of my newest colleagues at UMMP: evidence that the extinction of dinosaurs led to fundamental shifts in terrestrial environments, and that this signal is recorded in facies shifts tied to the K-Pg boundary: www.nature.com/articles/s43...

Spring in southeast Australia is very nice today. Here are some of the 80+ flowers in our garden today:

Should we be excited about the recent results from Mars? Absolutely! But we also need to understand exactly what they do, and do not, mean. 🧪🔭

🧪⚒️ I think this is interesting but has anybody done any serious thinking about how life might occur and evolve in non-water chemospheres, for example the surface of Titan? Water seems fundamental but is it the only way? www.seti.org/news/life-in...

It's the battle of index minerals today! Both are informative, both have use as gems, and both can be blue, but only one can advance to the next round. Head to mineralcup.org and vote for one today! #geology #mineral #MinCup25
