    The electric growth of gold in earthquakes with Dr Chris Voisey (Part I)

    Gold is one of the most chemically inert elements on the periodic table, and the fluids that carry it through the crust contain barely any of it… so how on Earth do we end up with enormous gold nuggets? Dr Chris Voisey, research fellow at Monash University, joins Wonder to talk about the geology of gold deposits, the mystery of how gold nuggets actually form, and the weird property of quartz crystals that might hold the answer: piezoelectricity. This is part 1 of two conversations we have with Chris – say tuned!! Find more from Dr Chris Voisey from his piece in The Conversation, 'How do you make a giant gold nugget? Take a vein of quartz, add a few thousand earthquakes'. Or check out his article in Nature Geoscience 'Gold nugget formation from earthquake-induced piezoelectricity in quartz'.

  2. From the Himalaya to Uluru, Dr Melanie Finch explains how the greatest mountains on Earth grow

    From the Himalaya to Uluru, Dr Melanie Finch explains how the greatest mountains on Earth grow

    Fifty million years ago, two colliding tectonic plates began building the biggest mountain range on Earth today. Structural geologist Dr Melanie Finch from the University of Melbourne joins Wonder to explain exactly how these mountains are rising: deep in the crust, where it's too hot for rocks to snap, thin layers of rock flow like honey, slowly pushing everything above them skyward. These are shear zones, and just three of these conveyor belts built the entire Himalaya. In this episode, Melanie takes us from the marine fossils sitting on top of Mount Everest to the five kilometre high mountains that once stood in the middle of Australia – where, to our delight, we also detour into the geological story of Uluru. Find more beautifully written pieces by Melanie in The Conversation, 'The epic, 550-million-year story of Uluṟu, and the spectacular forces that led to its formation' and on her website.

    Why Lithium in the Universe is an Elemental Mystery, with Professor Brian Fields

    It's the lightest metal on the periodic table and a crucial component in our modern technologies... but lithium also presents a fascinating cosmological problem. Professor Brian Fields joins WONDER podcast from the University of Illinois and shares with us the mysteries of primordial lithium formation in the universe - a story that takes us from interstellar dust to the big bang itself. Turns out, geologists aren't the only ones hunting for lithium... Thanks to the ⁠⁠⁠⁠⁠⁠Geological Society of Australia⁠⁠⁠⁠⁠⁠ for making this episode of WONDER possible!

    The Lightest Metal on Earth with Professor Carl Spandler

    Professor Carl Spandler joins WONDER podcast to walk us through the lightest metal of all - lithium! We dive head first into Carl's world of critical minerals, from crystals the size of cars to manipulated markets and the 'science fights' behind the genesis of lithium ore deposits. Enjoy with us these explorations of the geological cycle of metal on Earth... soon enough these stories will take WONDER deep into space and the beginning of time itself...

    Geological Kinship Across the Pacific with Nick Zentner

    On todays episode of WONDER, Holly & Anthony cross live to Washington State for a chat with Nick Zentner! Nick is a professor at Central Washington University and he chats to us live from Ellensberg (not Seattle; close but no cigar for Holly, can't tell you why that brain fade happened!!)... Here we cover the ancient kinship between Australian and North American geology, and also, we explore the sense that human wellbeing deeply links to those conversations about Earth that bring joy and closeness to our lives. https://www.nickzentner.com/ Thanks to our sponsors at the ⁠⁠⁠⁠⁠⁠Geological Society of Australia⁠⁠⁠⁠⁠⁠.

    Treasure Hunting with Dr Ross Chandler

    Well hello there! On todays show, Holly and Anthony sit down with Dr Ross Chandler to figure out how to find Australian orebodies... We break down the world of mineral exploration, covering everything from why and how we find new deposits to the ways we can think about their value. We chat about those critical metals that you hear about in the news like lithium and rare earth elements (REEs), and most excitingly, Ross lets us in on the dream: the inside story of his involvement in the Yin REE deposit discovery! So ... who's up for treasure hunting? Ross joins us from the ⁠ARC Critical Resources for the Future⁠, who made this episode of Wonder possible!
