... and winner of #MinCup 2023. Just saying... 😁

This is an excellent piece of ⚒️🧪 work, and will be a deep rabbit hole to explore. Already learnt: that 'analysis' is plural and 'analysin' is the singular; that Captain Cook introduced the word lagoon into English; and the term 'mantle' for the layer below the crust didn't appear until the 1940's.

Vote #Stibnite (Sb₂S₃) for #Mincup25 ⚒️🧪 because it was the likely source of antimony that literally wrote history. The chemical symbol for antimony is ‘Sb’ from ‘stibium’ the Latin for, you guessed it, #stibnite. Let's revisit a 🧵 from last year /1 buff.ly/md0dreE

⚒️🧪 #Mincup25 begins! Let's start with a PSA: • Please don't take a handful of fluffy stuff into a laboratory to ask for a microscope to see if it is asbestos. That tends to get people excited for all the wrong reasons. True story. • Vote #pectolite because it isn't trying to kill you.

#MinCup25 Round 1 Match 1: Hazardous (but useful!) #Chrysotile faces off against stunning gem #Pectolite. Do you pick the forbidden cotton candy, or the anti-pulverization beauty? VOTE: www.mineralcup.org/2025/vote/r1... Check RESULTS: www.mineralcup.org/2025/results...

Meanwhile, back in 🇦🇺 Australia... another addition to the already chonky list of Things That Will F**k You Up. www.theguardian.com/environment/...

Very ooh!

I remember these from ⚒️🧪 field work on the tundra north of Yellowknife. A yummy treat on long traverses. I was conscious that these are a major and time-restricted food source for many creatures including bears, but we had lost a cantaloupe to a bear 'visiting' our camp so I considered it a trade...

1/28 New thread ! This time we discuss the connections between my various passions: palaeontology, archaeology, and history, or how ancient civilizations (Pharaonic Egypt, Ancient Greece, and the Roman period) dealt with fossils and extinct animal bones #Paleosky ⚒️🧪🏺

Hello, I'm a Lab Manager in a film. The lab has glass walls and blue LED lighting everywhere. The world-class security system can be bypassed with chewing gum. A mass spectrometer can be installed and produce results by the afternoon. In a moment of distraction, something in the Lab will kill me. ⚒️🧪

For any ⚒️🧪 fans in Canberra 🇦🇺 on 8 and 15 August for #NationalScienceWeek... a rare opportunity to see the geological foundations of Parliament House! parliamenthouse.respax.com/public/aph/t...

Updated geoscience ⚒️🧪 educational resources from the awesome Education Team at #GeoscienceAustralia - including links to a digital exhibit about the Ice Age land bridge between mainland Australia and Tasmania plus a professional development STEM Summer School in 2026.

What a great ⚒️🧪 tool - my 🎂 birthquake is a chunky M6 just of Kyushu. What is yours?

An exciting ⚒️🧪 research opportunity...

International Rock Day ⚒️🧪 picture: Concretions on Ward Beach in the northeastern South Island, New Zealand 🇳🇿. These rocks are late, late Cretaceous rocks and the famous K-T boundary is nearby.

And we could tell you the ore body that the iron came from... ⚒️🧪

It's such an Australian 🇦🇺 thing to flex about how deadly the snakes are in a First Aid training course... 😬

💯 This is a cool geospatial application! ⚒️🧪 I wonder what other comparisons are possible? How far are seismologists from locations of M7 earthquakes? How far are geophysicists from a fundamental gravity network node? How far are economic geologists from an operating mine?

Rutile is also an awesome geochronometer because it can record both temperature and time. With high Pb closure temperatures and temperature sensitivity to Zr, rutile helps decode metamorphic thermal histories that other minerals miss. 🧪⚒️⌛

No apologies needed. All is as it should be. 💯 ⚒️🧪

No apologies

Geology always wins... ⚒️🧪

As a child I excitingly heard this on the news (astronomy was my huge interest at the time 🧪🌙⚒️). But I then baffled my poor mother by immediately plummeting into tearful despair that "they would discover all the planets before I grew up to find my own". Happy to be proven wrong! 😁

Another Red Wing is in the books! My geology clubbers and I ran two outreach events at this 3 day Roots music festival and spread understanding about Virginia geology! ⚒️

And now the Winter #Solstice from the same location ⚒️🧪🌏 A noticeable lack of celebrants due to an effective demonstration of seasonal change with a brisk minus 6°C air temperature... 🥶

And because coincidences... today I saw some archived ⚒️🧪rock samples from Antarctica collected from a glacial moraine in 1957. The 🤯 thing is that these cobbles are *rounded* - they were made by water flowing in a river. They whisper of a time when Antarctica was a very different place.

An interesting approach in applying ⚒️🧪 earth science to support the economics of energy transition.

More Mountains. Entombed. In. Ice. ⚒️🧪

Want to know more about ⚒️🧪 Rare Earths? Check out the recording of last week's Geoscience Australia 3-part seminar. Dr Karen Soldenhoff's talk about the REE supply chain is fascinating, as are Dr Jessica Walsh on mineral potential modelling and Dr Mark Pearce on finding REE in regolith.

Holy mackerel! Check out today's Kilauea eruption www.youtube.com/live/BqmpkUd...

This morning’s magnitude 5.2 earthquake near Nyngan is the largest earthquake to have occurred in NSW for over 30 years, since the M5.3 Ellalong earthquake in 1994 that occurred 5 years after the deadly M5.4 Newcastle earthquake in 1989. Fortunately today’s epicentre was in a remote area.

As a PhD I was warned off an area because a senior researcher 'had plans' - that didn't actually eventuate for 10+ years. It was a wasted opportunity for collaboration. Others I knew were so boxed in by 'long toes' they were effectively ejected from academia. Everyone loses with this behaviour.

Some sad news this week for those in the isotope ion microprobe business ⚒️🧪. The Father of the SHRIMP (and my PhD Supervisor), Bill Compston passed away at 94 years. My scientific career would have been very different without him. Vale. earthsciences.anu.edu.au/news-events/...

For when your house *is* the rock collection ⚒️🧪 www.theguardian.com/us-news/2025...

An exciting ⚒️🧪 preprint to peruse from some esteemed colleagues looking deep into the heart of #zircon geochronology to understand what chemical abrasion does to the mineral structure and radiogenic isotopes. The authors would love feedback and discussion! egusphere.copernicus.org/preprints/20...

It's universally recognised that basalts make fertile soils - in the right conditions. This alternate-to-fertiliser is intriguing, but I assume that making a fertile soil requires a few more factors than crushed rock? Any ⚒️🧪 #soil scientists for a comment? www.abc.net.au/news/2025-05...
