Tetrapod trackway Tuesday! 🧪⚒️🐾

October 27, 1827, birthday of Italian geologist and paleontologist Igino Cocchi (1827-1913). He was instrumental in promoting geological studies in Italy and a founding member of the Italian Geological Society ...

Congratulations to Dr Tim Pharaoh , a retired member of BGS, who was awarded the André Dumont Medal 2026 recognising his career on the Paleozoic era of the British Isles & Northwest Europe. The award was presented by the Geologica Belgica Luxemburga Scientia and Professionis ‘Master Day’ event.

"All capsicums start out green, and their colour changes to yellow, then orange and finally red as they ripen. But the difference between the colours isn’t just superficial – it affects nutrition, flavour and more." #Capsicum #Nutrition #Plants #Flavour #Food

This morning's magnitude 4.9 earthquake occurred about 100km from the South Australian coastline, 15km below the continental shelf. A magnitude 4.0 occurred nearby in 2015. The largest earthquake in the region was a magnitude 6.6 near Robe/Beachport, almost 130 years ago (bottom right of the map).

🧪⚒️Tiny grains of coesite — quartz that forms only at pressures found about 100 km down — turned up in rocks of western Norway. On the new Geology Bites, Torgeir Andersen explains how buoyant continental crust got that deep, and how it came back. geologybites.com/torgeir-andersen #geology

Meh. Was told there’d be water. 1 ⭐️

Oh, there's a downhole DAS in the SAFOD borehole. *And* it's been exactly 22 years since the last Parkfield earthquake. Fun data set, soon. Maybe....

Aww, crap ... it's #MolluskMonday and I haven't posted anything yet 😅 So, howzabout everyone's favorite poly/enby sequential hermaphroditic snail, the slipper shell Crepidula? 🧪⚒️🐚

For #MineralMonday, a beautiful example of amazonite, a relatively rare example of a green potassium feldspar (microcline) from the Pikes Peak region. 🧪⚒️💎

Post your Arab colleagues/predecessors "Muawia was born to Badeah Sukkar and Muhamed Nor Al-Deen Barazangi on 14 September 1941. He grew up in the city of Damascus, Syria, and graduated in 1965 from the University of Damascus with a bachelor’s degree in physics and earth sciences with distinction."

There has been more than one discussion of South American tectonics in a Cheesecake Factory in Tucson.

very serious work happening during midterms in the geology grad office (ignore the spellings i am far too dysgraphic to get them right for this lol)

Tree roots are hugely important for the functioning of the Critical Zone. Our latest post to Substack shows how geophysics can help us better understand the distribution of roots non-invasively. 🧪🔬🌲 Radar Reveals the Secret Architecture of Tree Roots criticalzonenews.substack.com/p/radar-reve...

“NASA scientists can track fall color by measuring how much red, orange, and yellow forests show compared with green. Tracking the ratio over time reveals where leaves are changing and when color peaks.”

“At just 11 years old, Reese has already turned her love of rocks and minerals into a museum, a creative business, and a workshop where she cuts and polishes stones to reveal the colours and patterns hidden inside. 'Pebble Rebel Dune Saloon' is located near Liebenthal, in West Central Saskatchewan”

Friday was good, spent scouting the Estelle Mine Tunnels in the middle Silurian for an upcoming SE GSA field trip. ⚒️

⚒️ 🧪 Earthquakes have been swarming offshore Vanuatu. What’s going on in this corner of the world? More fascinating than this latest swarm is the history of islands perched above the subduction zone, carried up and down by movement of the slab below. earthquakeinsights.substack.com/p/earthquake...

New paper in the wild! 🧪⚒️ Dolomite is a weird mineral, for many reasons. One of which is that most of it is old. But there is a bit of new dolomite, such as in the Abu Dhabi sabkhas, and we used those to control for the seawater signals dolomite retains. Link: https://doi.org/10.1130/G55014.1​

Science plus art.

This is what you do when you have a boatload of data and talent.

I can’t think of a more appropriate ending for the 10th Anniversary of #MinCup than Quartz winning, the mineral that started it all! Thank you to @mikamckinnon.bsky.social and the team for all the tireless work you do! The ballot stuffers can stuff it, though!

Shocked #Quartz is one piece of evidence that helps identify large impact areas, like the one left by Chicxulub asteroid. The quartz crystals develop a series of parallel laminae, called shock lamellae that indicate deformation, or breakage of the crystal along multiple, parallel planes. #MinCup26

We have a wealth of great geoscientists on this platform. Share your favorite quartz insights, opinions, jokes, memes, pictures. Even do the other guy if you must, although red is still overrated 😆. This is the finale!

There has been a lot of talk about piezoelectricity in the match, but little about exposure dating. Vote #quartz in #MinCup26 for the O2 atoms in the quartz crystal structure & the predictable way they are converted into beryllium isotopes when exposed to the Universe and not inside a mountain.
