    The Australia-India Partnership: CSIRO on Critical Minerals Exploration Across Continents

    🌍 Unlocking Earth's Critical Minerals: Inside CSIRO's Australia-India Partnership When you connect wirelessly to anything, you have CSIRO to thank - they are the ones who invented Wi-Fi. But beyond the banknotes and wireless tech, Australia's national science agency is working on something equally important: methods to find the critical minerals that will power the future. Funded by the Australian Government, the India-Australia Critical Minerals Research Partnership ran from January 2023 to 30 June 2026, advancing sustainable and environmentally responsible critical minerals development for the benefit of both nations. As part of a special partnership with The GeoCo and Wonder podcast, we sit down with Dr Louise Schoneveld and Dr Eric Romaneido from CSIRO's Mineral Resources Group and discuss this important multi-year research collaboration that they have been part of. From the dense forests of Meghalaya to the ancient weathered rocks of Odisha, this is the story of how science travels, how geology shapes exploration, and how Australia and India are building resilience in global supply chains. It's a love letter to fieldwork and the diverse, brilliant minds making modern minerals exploration smarter. In this episode: 🔍 Why critical minerals matter (and why you should care) ⚒️ CSIRO's greatest hits and their mineral resources mission 🗺️ Exploring the three distinct geological region across India where the research fieldwork was undertaken: jungles, deserts, and weathered coasts 🌏 The Australia-India partnership tackling sustainable mineral development 👥 All about the diverse team running the program, spanning postdocs, students, and research scientists from Australian and Indian institutions. 🔗 Find us: @theGeoCo on YouTube 📻 Wonder on Spotify @theGeoCo on TikTok and Instagram Geoco News on Substack: thegeoco.substack.com We acknowledge the Kaurna people of the Adelaide Plains, on whose country the Wonder podcast is made. — Holly, Anthony & the CSIRO Australia-India Partnership team

    Shared origins for the Yilgarn's precious metals?

    Australia's largest platinum deposit was hiding 70km from Perth CBD, and nobody had thought to look. In 2020, Chalice Mining drilled the very first hole at a site on the western edge of the Yilgarn Craton, ancient geology everyone had ignored because the exciting stuff was supposed to be much further away from the city.... That hole hit platinum, palladium, nickel, and copper. It was Australia's largest PGE discovery in history. There is a road that passes within 200 metres of it. Generations of geologists drove right by. Matt Demmer is one of the economic geologists working to understand the Gonneville deposit ever since, first with Chalice Mining, now also completing his PhD at the ARC Centre for Critical Resources. He joins Holly and Anthony to discuss how you find things nobody expected, what the sulfur isotopes inside the rocks are whispering about deep Earth recycling, and why thinking about mineral systems as interconnected planet-wide stories might be the key to finding the next one. A 15-year industry career feeding directly into frontier academic research: as Holly puts it, spectacularly punk geology. ---- Make sure you're following Wonder wherever you get your podcasts — and chuck that notifications bell on!

    Why the Earth's surface yo-yos: Dr Mark Hoggard on the flowing mantle

    The Earth bobs up and down like a yo-yo over geological time, and it's drawn a treasure map of the world's metals... What if the ground beneath your feet has been silently rising and falling for millions of years, driven not by earthquakes but by something churning deep in the mantle? And what if that same invisible process explains where the world's great copper, zinc, and nickel deposits are hiding? Dr Mark Hoggard (ANU and previously of Cambridge, Harvard, Columbia) joins Holly and Anthony for a conversation that will genuinely change how you picture Earth. Starting with a tour of the solar system's rocky planets and ending with a treasure map of Earth's metal deposits, this one covers deep Earth dynamics, dynamic topography, the mystery of the Eastern Highlands, and how the thickness of tectonic plates controls where critical minerals form. "The idea that old rocks in the middle of Australia do nothing for a billion years is not true," Mark says — and by the end of the episode, you'll understand exactly why.

    Tasmania's epic geological record with Dr Jacqui Halpin

    On today's episode of Wonder, Holly & Anthony are joined online by Dr Jacqueline Halpin from the University of Tasmania for an armchair geological tour of one of Australia's most spectacular and surprising places. If you've hiked the Overland Trail, wandered Salamanca, or stared up at kunanyi/Mt Wellington from the Hobart warf, this one is for you. Tasmania's geology is in-your-face, world-class, and wildly underrated! It turns out the rocks of Tasmania have a story that starts not on this continent, but in North America, 1.4 billion years ago. From the ancient quartzites of Rocky Cape (cousins to the Rocky Mountains), through violent continental collisions in the Cambrian, Devonian beach granites, Gondwana-breaking dolerites, and a Pleistocene ice cap that carved the deepest lake in Australia... Jacqui walks us through the extraordinary archive written into Tasmania's landscape.

    Our fishy ancestors: Dr Alice Clement on the palaeontology of the lobe-finned fish

    Did you know that humans are a type of lobe-finned fish!? Turns out our story begins 400 million years ago, when some very special fishies began making the move from sea to land, and we want to talk about it!! Dr Alice Clement heads up the Early Vertebrate Evolution Lab at Flinders University and has dedicated her career to understanding this history of life on Earth ... how the evolution of fish is the story of our own beginnings, too. Alice joins us in the studio for a conversation about her first fieldwork at the GoGo Formation in the Kimberley - one of the most extraordinary fossil sites in the world - to the moment she split open a limestone nodule and found a beautifully preserved fish inside (now on display at Melbourne Museum!). Alice brings the joy of discovery into every corner of this fun episode. One of our favourite moments was when she walked us through her favourite fossil - an Elpistostege - a predatory fishapod from a famous site in Quebec that Alice then helped image using high-powered X-rays. The x-rays revealed finger bones, hidden inside a fish's fin, that are anatomically equivalent to your own. How good! And we get the full story of Materpiscis, the pregnant fish with a fossilised embryo and umbilical cord still intact, whose species name is Attenborough (yes, the Sir David...). Alice is a wonderful guest, and this won't be the last time you hear her on Wonder. Thanks to the Geological Society of Australia for making this episode of Wonder possible!

    Discovering an ancient continent & other wild adventures in Madagascar with Professor Alan Collins

    What does it take to discover a continent? Apparently four months in the Madagascan wilderness with no phone, some crunchy crickets to snack on, and a whole lot of time bouncing around on terrible roads in a beat-up Peugeot while thinking some very big thoughts. Professor Alan Collins from Adelaide University joins Holly and Anthony for a conversation that spans the formation of Gondwana, the naming of a long-lost ancient continent, and the importance of being beautifully, productively bored. This is a genuine delight as Alan shares with us his vintage field photos, stories of sleeping in remote villages, learning Malagasy on the fly, and finding dinosaur bones by the side of the road. What a geology-kinda-life!! And the science? Alan's research reconstructed continental collisions 600–700 million years ago when the oceans were pink and the continents a rusty-red... and a mountain range as mighty as the Himalaya that has long since vanished. Alan walks us through the plate reconstructions and explains why understanding all of this helps us understand why our planet turned out the way it did. Oh, and we find out where the name Azania actually came from. Spoiler: it involves a very well-thumbed Lonely Planet! Alan is a returning guest on Wonder. If you’ve heard him before, you’ll already know why we had to get him back. If you haven’t, this is a very good place to start.
