Glad to share our new study at "Nature Communications" which resulted from several workshops on the early warning signs of mass extinctions and coordination of macroevolutionary vulnerability and the states of carbon cycle and temperatures. https://www.nature.com/articles/s41467-026-75655-9 🧪⚒️ #Geology #Paleobio #EvoBio

💁🏻‍♀️ TIL: 🌍🧭 Researchers at the University of #Barcelona built a free web tool that converts current #fossil coordinates to where those locations sat millions of years ago. It runs five global plate tectonic models simultaneously and shows automated results nearly identical to desktop #software, with an average spatial error under 17 meters. 👉 https://scitechdaily.com/where-on-earth-was-this-fossil-200-million-years-ago/ #paleontology #platetectonics #paleogeography #universityofbarcelona #geology #map #science #earthscience #cretaceous

Gros Morne: Walk on the Mantle At Gros Morne National Park, you can walk on the Earth's mantle. This UNESCO site in Newfoundland features the Tablelands, a massive slab of rust-coloured peridotite rock forced up from deep within the planet. This barren landscape, where few plants survive, is a visible lesson in plate tectonics and stands in stark contrast to the park's lush, green fjords. #Canada #GrosMorne #Geology #Newfoundland 🇨🇦 https://en.wikipedia.org/wiki/Gros_Morne_National_Park

Happy birthday to #geologist & oceanographic #cartographer Marie Tharp (1920-2006), whose pioneering, thorough & complete ocean floor maps with Bruce Heezen, made using realms of echo sounder data, revealed the Mid-Atlantic Ridge.⁠ ⁠ After studying #geology & math, Maurice ‘Doc’ Ewing at Lamont-Doherty Earth Observatory at Columbia hired her to draft 1000s of echo sounder profiles. 🧵1/5 https://minouette.etsy.com/listing/217247292 #sciart #printmaking #womenInSTEM #histsci #linocut

💁🏻‍♀️ TIL: 🕳️🔥 A Soviet drilling accident in 1971 collapsed a #gas cavern in #Turkmenistan, creating a 70-meter #crater engineers set on fire expecting it to burn out in weeks. It burned for over 50 years until the #government ordered wells drilled to capture the #methane, and satellite #data confirms the flames have dropped by more than 75% since 2022. 👉 https://boingboing.net/2026/07/23/darvaza-gates-of-hell.html?fk_bb #darvaza #geology #earth #science #naturalgas #climate #desert #robots #engineering

🌊 In September 2023, seismometers around the world detected a mysterious signal repeating every 92 seconds for nine straight days. The source: a standing wave trapped inside a Greenland fjord. Here is what happened. A glacier in East Greenland had been thinning for years, no longer supporting the mountain slope above it. On September 16, about 25 million cubic meters of rock and ice collapsed into Dickson Fjord, triggering a tsunami with a runup height of 200 meters near the impact. The fjord is 540 meters deep, 2.7 km wide, with walls taller than 1,800 meters. That geometry trapped the wave energy. The tsunami stabilized into a seiche, a standing wave sloshing back and forth across the fjord every 90 seconds. Each oscillation shifted millions of tons of water, loading and unloading the crust below, generating seismic waves detected globally. The signal decayed extraordinarily slowly. It was still detectable after 9 days. A second, smaller event happened October 11 from another landslide in the same gully. In 2025, the SWOT satellite directly observed the seiche, confirming the theory. The study published in Science calls it the first evidence of fluid sloshing persisting for days without an external driver. The landslide was preconditioned by climate-driven glacial thinning, the first such event recorded in East Greenland.

Looking remarkably like you need a set of watchmakers screwdrivers are these fossilized crinoids, brachiopods, and bryozoans. Do zoom in btw! 🔍 Body parts of ancient marine creatures that lay scattered here on an ocean floor over 300 million years ago.

We were in New Hampshire last weekend and discovered this gem: Sabbaday Falls cuts down through a basaltic dike intruded into the surrounding granite. A highly effective visual demonstration of these rocks' relative hardness! #geology #waterfall

"A Massive Flow of Rock and Mud Tumbled Down Mount Rainier Centuries Ago. Scientists Pinpointed Its Date to Better Understand the Volcano’s Complex Threats" by @Smithsonianmag@flipboard.com - Communities downstream from Mt Rainier have lahar (volcanic mudflow) drills where residents walk to higher ground. One of those historic mudflows has been more precisely dated to 1507 as scientists learned how to correlate rock layers, tree rings & radiocarbon dating. https://www.smithsonianmag.com/science-nature/a-massive-flow-of-rock-and-mud-tumbled-down-mount-rainier-centuries-ago-scientists-pinpointed-its-date-to-better-understand-the-volcanos-complex-threats-180989162/ #volcano🌋 #geology #PNW

SedsOnline is now accepting abstracts for their 14th Student Webinar on 28 October 2026. If you're an MSc or PhD student working on evaporites or other chemical sediments, we'd love to hear from you. Submit your abstract by 30 September 2026: https://forms.gle/LZ2tXGvxf1fQrk1e9 #Geology #Sedimentology #Evaporites
