Pyritised, metamorphosed, and faulted #Archean microbial mats from South Africa. I love the colours on this one. #geology #paleontology

Here’s a really nice alluvial fan I thought you should see

For Day50 of photoshopping @lastweektonight.com's John Oliver with fossils in the hopes that he saves the Paleontological Research Institution Celebrating 90yrs of mollusk research at PRI! John is joined by a number of other H. sapiens who love science (and fun)-tag them all! 🧪🦑⚒️🐌 #fossils #savePRI

I sometimes take advantage of the analytical equipment at my real job. This is a Cambrian arthropod (probably not a Beckwithia) from the Wheeler shale of Utah. I used the XRF (X-ray fluorescence) to highlight iron and phosphorus. This is a 500 Ma digestive system. #FossilFriday

I am pleased to announce that my department (EAS at Nebraska) is hiring a teaching postdoc for AY 2025-2026 in the area of Earth Materials! I'm not on the committee but am spreading the word to my mineralogy/petrology networks on behalf of the committee. See ad for more details.

Unsurprisingly, @tressiemcphd.bsky.social is spot-on in this analysis: “A.I.’s most revolutionary potential is helping experts apply their expertise better and faster. But for that to work, there has to be experts.” www.nytimes.com/2025/03/29/o...

We are assuming this was a planetary scientist traveling to the Lunar and Planetary Science Conference

Who’s guilty of the discrepancy between minerals and whole-rock chemistry in plutons? Melt extraction might be innocent—mineral reequilibration is likely the real culprit! Fresh out on Pi Day by me, Brenhin @brenhinkeller.bsky.social, & Changqian! doi.org/10.1029/2024...

New: A NOAA lab in Hawaii that is connected to the longest-running observation of global greenhouse gas concentrations is slated for closure in August, according to a list of lease terminations Democratic members of Congress shared with @washingtonpost.com.

Fresh & dense picrite, fresh aphyric 'a'a, basalts with infilled vesicles, and basalts with sharp flow contacts. just a few of the #hawaiian lavas cored well below modern sea level on #IODP #exp389 are showing a surprising range of #volcanic textures... all in the first site we've examined thus far.

For any earth science grad students looking for a postdoc next year! ⚒️🧪

Discover new ways to compile Julia! Smaller binaries, AOT compilation with 'juliac,' and trimming tools for efficient deployment. juliahub.com/blog/new-way... #JuliaLang #JuliaCon #SoftwareDevelopment #Optimization

📢New Paper📢 In our opinion piece "The Hunt for Holocene Abrupt Climate Change" in #PLOSClimate, Nick McKay and myself ask why are ACCs found easily in individual studies but not in compilations? doi.org/10.1371/jour...

This was a great #AGU24 presentation by Joel Wilner! Great timing.

New paper on glacial erosion rates and the Sadler effect that came out of a @dartmouthears.bsky.social grad seminar class just out now in Sci Adv! doi.org/10.1126/scia...

Geoscience folks, have you seen all our skeets about how NSF/EAR has reorganized? Now there's a one-stop-shop for all the info: new.nsf.gov/geo/updates/... (note the webinars happening this week! come ask your questions!)

Fluid inclusions in this Cambrian quartzite are just amazing. These CO2 and O2 bubbles vibrate, endlessly. These are likely from a widespread late Paleozoic fluid event (same as Herkimer diamonds?). Inclusions are 20-30 microns: ~1/3 the width of human hair. (Mosherville SS of Galway in NY).

We wrote this about predictive AI rather than generative AI, but the hype-functionally ratio has only blown up in the genAI era. Something’s gotta give.

This is a map showing the orientation of diopside in a deformed symplectite. This used to be an omphacite, which tells us that the rock used to be at very high pressure (great depth). ⚒️🧪 If you want to read more about how such symplectites nucleate and deform: link.springer.com/article/10.1...

Hello @bsky.app from the #JuliaLang community! We're excited to start posting here on Bluesky in addition to our other social media, all of which can be found here: julialang.org We'll keep you updated on our fantastic community, our conferences, #JuliaLang updates, and more on this profile!

New Episode of the #julialang Dispatch Podcast! Here we talk with Jeff Bezanson, one of the creators of the Julia Programming Language, on topics such as static compilation of Julia programs, ahead-of-time compilation of binaries, and more! www.youtube.com/watch?v=4CV5...

I went to a summer school in Corsica about earthquake and faulting. But will you look at this dyke. #geology

New preprint up! We sequenced hundreds of samples from across one of Earth's oldest living organisms - the Pando aspen clone - to understand how mutations accumulate and spread in long-lived clonal organisms. Our results were…surprising. 1/30

Magmatic enclaves are typically mafic (darker) inclusions w/in felsic (lighter) igneous rock caused by mingling of magmas in the magma chamber. This swarm looks like fishes swimming with current & have experienced some shearing. Note the lighter dikes cutting across some of the enclaves. ⚒️🧪👇🏼 geology

A mountain top falling 1200 m into fjord created a huge 200-m tsunami locally a year ago on the coast of Greenland. @seismo_koel and Weite Boome and Søren Rysgaard share the details on Science in Action this week. Thx to @seismo_steve for the heads up. www.bbc.co.uk/programmes/w...

The Jack Hills zircons showing the mid-Hadean (4.5-4.0 billion years ago) Earth to be cool enough for a hydrosphere and possibly already already possessing microbial life is one of those things people should know more about. Life may literally be older than the rock record.

The Department of Earth Sciences at Dartmouth is looking to hire a tenure track Assistant Professor of Geophysics! Review of applications will begin on October 15, 2024 and continue until the position is filled. For more information and to apply, visit apply.interfolio.com/152376

In my latest I report on a paper by Kasbohm et al remarkable for 3 reasons: 1 it upends ideas on the trigger for climate warming in Miocene; 2 it’s the 1st successful radiometric dating of *sediments* drilled from beneath the seabed; 3 it confirms orbital models! arstechnica.com/science/2024... 🧵

Perovskite could be a mantle rock ejected from a volcano, or formed in a kimberlite pipe. It can also form in a Brown dwarf! Would give it the physics vote yet without copper what’s left of electronics? Copper also gets the art vote for its role in bronze & sculpture so many blue/green pigments… 🧵

MICI (Marine Ice Cliff Instability) less likely as glacier front expected to thin towards coast, reducing cliff height 🧪⚒️

🧪⚒️ Beautiful patterns created by faulting of layered sedimentary rocks overlain by stream beds in Turkmenistan.
