⚒️🧪 Travel back 635 million years with Dr Caleb Bishop, #GeoscienceAustralia geoscientist. Discover evidence of life surviving beneath ❄️🌏 Snowball Earth's ice sheets in WA’s Officer Basin and how it’s reshaping our understanding of algae and the rise of animals. 11am, 22 July. ga.gov.au/publictalks

#GeoscienceAustralia Mobile Laboratory ⚒️🧪 had 1,000+ visitors at the Alice Springs Show, showcasing satellite imaging, groundwater, earthquake monitoring and regional geoscience. Despite wet weather, strong engagement highlighted the value of #scicomm and outreach (& earned a show award!)

The formation of the East Antarctic Ice Sheet has stumped scientists. Could a tectonic event that took place tens of millions of years prior offer an explanation? eos.org/articles/the...

From rocks to reservoirs, the ⚒️🧪 #GeoscienceAustralia Laboratory is decoding the organic fingerprints of the Earth to unlock clean energy, carbon solutions, and future resources. Join us and help lead the next wave of geoscience innovation! #ScienceJobs #ChemJobs #LabJobs

10 June marked 140 years since the volcanic ⚒️🧪 eruption of Mt Tarawera near Rotorua 🇳🇿. My main memory of this famous image is as a slide in 1st year geology course where the lecturer pointed out the figures in the middle: 'Look how excited they are! They must be volcanologists!'

Sounds intriguing, there is more detail here: spaceweekly.com?p=801385. Although the concept does raise images of large horseshoe magnets and misguided coyotes. Better check that this isn't being sponsored by Acme Corporation...

Heading into conference abstract / presentation season, I 100% recommend Kathryn Langin's (@kangin.bsky.social) "Tell me a story! A plea for more compelling conference presentations". It's short, sweet, and not just for ornithologists. I can get behind every word! 🔒 academic.oup.com/condor/artic...

This was a fortuitous and intriguing juxtaposition in my feed... layers at all scales!

Hydrogen is a renewable fuel of the future, but how to store it? Is underground an option? #GeoscienceAustralia ⚒️🧪 has an free online public talk on 27 March about how geological storage of hydrogen works, whether it can work for Australia and how it is working for industry in other countries.

The #GeoscienceAustralia ⚒️🧪 Public Talks are restarting! On 18 March is 'Numerical tectonic reconstruction of the Tasmanides: Integrating Australia, Antarctica and Zealandia into a global tectonic framework (580–250 Ma)' A fascinating region! events.teams.microsoft.com/event/e33ea3...

Know any 🦘🥝 STEM graduates ⚒️🧪💻 interested in making a meaningful contribution to public knowledge at #GeoscienceAustralia? Please encourage them to join in this online public talk next Tuesday, 17 March.

The meaning of precision in geographical degrees. ±100°: You don't know where it is. ±10°: You know it's on a specific continent. ±1°: You know it's within about an hour's drive. ±0.1°: You could bike to it. ±0.01°: You could walk to it. ±0.001°: You could probably see it.

This article is amazing.

Just submitted the paper on this today. You can find sneak peaks on the models here www.thingiverse.com/GEUSVR/designs + other geology 3D-models

Steve's photo hung up in my office at my one job. This is from about ten years ago. Not a great print bought online, but hey, I had my own office for the first time. Had to zhuzh it up. Work at a science place? Put up some science wall art.

Awesome ⚒️🧪 paper with clever use of soft sediment cores and CT scanning to deduce the location and size of ancient earthquakes to help plan for future events. www.science.org/doi/10.1126/...

Scientists: for a new story, I have one big question—> What is a “good day” in the lab? I’m looking for epic examples of the best day ever to general criteria for what constitutes a “good day” compared to a nothing-burger day. Ping me if you have examples to share! Re-posts appreciated!

A most sensational inspirational celebrational Muppetational thread... (And go watch the Muppet Show special if you haven't already. It. Is. Awesome.)

Didn't realise there was an overlap between 🏹 archery and ⚒️🧪 seismology, but I'll now be looking for earthquake resistance features next time I buy arrows...

Some amazing footage (no cloud cover!!!!) from Subantarctic Heard Island captured a few days ago by members of the Australian science expedition. #volcano #Antarctica #HeardIsland 🧪⚒️🌋

#OreCup #copper is one of only two coloured metals ⚒️🧪 The iconic reddish color is due to a peculiarity in the transition of electrons between the 3d and 4s orbitals causing absorption of blue and green wavelengths and reflecting red/orange wavelengths. Also makes it a great electrical conductor.

No flashy specimen pictures, just minerals by the billion - voting for #ilmenite in the ⚒️🧪 Ore Cup because it contributes to the awesome black sand beaches of #NewZealand 🇳🇿 . (PSA from personal experience: *always* bring footwear on a hot summer's day...) buff.ly/ez1xDOJ

Always a big ⚒️🧪 fan of #copper. We use it for vacuum gaskets which we then give away to visiting school groups - they find it fascinating because although copper is everywhere it's rare to actually *see* it. There's probably a kilo or so of copper in your immediate vicinity.

It’s almost time! We’re excited. You excited? Monday 00:00 GMT. 24 hours a match. This is going to be FAST

S**t, did we forget to put mithril on the list of ⚒️🧪 critical minerals?! buff.ly/122Ziq7

A great way to click together ⚒️🧪 #EarthScienceWeek2025 with a Lego speed build competition using the new 'Minerals' set of quartz, amethyst, tourmaline, pyrite, fluorite, and rhodochrosite. Pictures don't do them justice, they are quite spectacular in person. Alas, no #zircon - maybe in Set 2?

⚒️🧪 Great ShakeOut! Earthquake safety is not common knowledge in Australia where quakes are infrequent, but still potentially deadly. After a hefty M5.9 quake in 2021 that reached the Melbourne CBD, it was found only 3% knew what to do in a quake. Find out now! buff.ly/PNGYgTa #EarthScienceWeek2025

For #EarthScienceWeek2025: what 3 steps got you into ⚒️🧪 Earth Science? 1. A wood box full of rocks and crystals that my Dad had collected in his travels 2. David Attenbourgh's 'Life on Earth' 3. Couldn't make up my mind choosing a science major, so I did the (earth) science that does them all!

It's ⚒️🧪 #EarthScienceWeek2025 ! Here's a new product from the awesome Geoscience Australia Education and Outreach team: a Year 8-10 classroom activity exploring critical minerals in Australia and their value through the lens of topographic data and the geology of Australia. buff.ly/Y8v46nt

The greatest advance of the 21st century has been inflight WiFi because it has enabled having live geological maps on hand to more thoroughly investigate the ⚒️🧪 geology you are flying over. Window seats forever!

... 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.
