5.0 out of 5 stars from 48 ratings
  • Infectious fascination with the natural world

    Dipping my toes into science-based podcasts… the infectious joy from the two hosts of Wonder makes this an accessible and entertaining listen! Loved hearing about Hedda’s research into glacial changes and will definitely listen to more episodes.

    It’s always so good to hear people share their passions, you can hear the excitement in their voices.. and that’s infectious.

    Thanks Anthony and Holly!

Talking Points

Recent interactions between the hosts and their guests.

Carbonatites: to REE or not to REE?
Q: What did the Indian samples reveal about fertility versus barrenness in carbonatites?
The Indian samples showed rare earth element-poor carbonatites that still provide insight into magma history, which helps explain why some carbonatites remain barren and how their evolution may lead to future enrichment under the right conditions.
Carbonatites: to REE or not to REE?
Q: What is a carbonatite and how does it differ from typical silicate magmas?
Carbonatites originate from the mantle and are enriched in carbonate, making them distinct from silicate-rich magmas; they carry CO2, volatiles, and critical metals like rare earth elements in a way that influences their mineralogy and potential for enrichment.
Exploring for critical chromium, from the ground up (to space!)
Q: Cool. So Raphael, the Chromitite... could you help us dip our toes in to the general geology of this commodity?
Chromitite is a chromium-rich rock formed from magmatic processes; chromitites accumulate in layered bodies where chromite crystals crystallize and concentrate chromium, forming a major chromium resource in the world.
Looking for Lithium: from rocks in Rajasthan to laboratories in Western Australia
Q: What was it like travelling in this place?
The trip was fantastic; fieldwork in India offered unique geological and cultural experiences, and seeing similarities and differences with rocks in Western Australia provided valuable context for their projects.
Shared origins for the Yilgarn's precious metals?
Q: Why is the timing of the deposit's formation around 2.68 billion years ago important?
The age coincidence with gold deposits nearby suggests a shared crustal/mantle process operating over a large geographic scale, challenging the notion that these deposits form independently.
