The Lightest Metal on Earth with Professor Carl Spandler

WONDER ·

2025/10/12

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 to deep into space and the beginning of time itself... Carl joins us from the ⁠⁠⁠ARC

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

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

Welcome to another cracking geological conversation with Dr Sabin Zahirovic (or should we say, welcome to today's episode of 'what is Sabin 3D printing today'....!!??!!) Here we explore the great Australian tilt, what the mantle has to do with it, and what this continental tilt has meant for the natural evolution of our country. Sabin continues to show us some unbelievable data visualisations that reconstruct the deep Earth through deep time - you won't want to miss the video for

Ever noticed that the coastlines of Africa and South America match up like perfect puzzle pieces? Turns out we need to investigate Earth's youngest supercontinent, Pangea, to explain that one! In this episode of Wonder we're joined by the brilliant Dr Sabin Zahirovic, who shows us some mindblowing visual reconstructions of the Pangean supercontinent and the geologic mega-events that rippled through the earth system during its time.

Welcome to the ultimate deep time exploration Down Under! With Professor Pete Betts from Monash University, Holly & Anthony imagine the Australian continent as a geologic mosaic of stone. We ask about the origins of these cratonic blocks, and how they came together to form the Australian jigsaw we know and love today. Prof Betts walks us through it all, from missing ocean basins to that time he sticky-taped together the continent...(And a bonus scoop: he even shares the goss on what new ideas

Welcome to Kīlauea, one of the planet's most active volcanoes in the heart of Hawaii. You've likely seen its incredible lava fountains and ongoing eruptions in the news, or all over your social feeds ... Well, on today's show, we crossed live to geochemist and volcanologist Dr Abigail Nalesnik to talk everything Hawaiian volcanoes. What's up with lava fountains?? What do eruptions sound like (obvious hint: not what you might think)?? Why is Hawaii actually erupting at all??? To top it all off, we

Welcome to the rock bottom of the Australian continent. Here, hundreds of kilometres underground, there are inverted mountains and valleys beyond anything at our country's land surface. With Dr Caroline Eakin we find out how earthquakes paint pictures of Australia's deep roots, why our country experiences earthquakes, and finally, why those Western Australian's are building an epic 'telescope that points inside the earth'...A tremendous thank you to the ⁠Geological Society of

Today's show begins deep in Earth's mantle. It's mostly a beautiful, green place ... but, apparently, also much like a marble cake? On todays show, Holly & Anthony are joined by the ultimate mantle legend Dr Isra Ezad, who's an igneous experimental petrologist at the University of Western Australia. Dr Ezad walks us through the dark side of Earth's mantle, the kind of experiments that let her simulate these exotic domains, and how metal behaves in these weird subterranean

In today's show we traverse iconic Australian landscapes and uncover their roots in deep time. Dr Steve Hill shows us how 'reading landscapes' reveals their formation - by fire, by ice, by water - thus allowing us to imagine the ancient sculpture of todays world. We find out that encoded in our landscapes today are ancient inland seas, Australia's slow drift across the face of the Earth, and its transformation into arid, fiery lands...What an utterly joyous conversation— a big thank

Or that if you're a plant, you can actually have too much of a good thing, *cough cough atmospheric combustion??!!!?* ). During these fascinating Phanerozoic moments in Earth evolution, Dr Merdith also shows us what the ancient landmasses were doing .... and to voyage there, we must introduce you to Gondwana.Find us at
