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 spaces.We partnered with the ARC Critical Resources for the Future to make this fascinating episode of Wonder possible.Find us at ⁠⁠www.thegeoco.com.au⁠⁠Instagram ⁠⁠⁠⁠⁠⁠@thegeoco⁠⁠⁠⁠⁠Got questions?
