Cosmic Savannah - Ep. 42: Rockin’ All Over the World

Hosted by Dr. Jacinta Delhaize & Dr. Daniel Cunnama. In this week’s episode, we take a deep dive into how a planet (in this case Earth) is constructed! We are joined by Dr. Eugene Grosch who is a geologist and petrologist at Rhodes University in South Africa. Eugene discusses his work on some of the oldest rocks in the country and what we can learn from them.   We learn about how precious metals and diamonds are created and moved through the Earth’s crust. We also discuss how planets create the building blocks for life, and how life, in turn, helps to create the minerals we find on Earth!
