In this episode, Chris Bolhuis and Dr. Jesse Reimink dive into the complexities of Zircon grains from the Jack Hills conglomerate in Western Australia—some of the Earth's oldest fragments. They discuss the environmental conditions necessary for their formation and survival, the role of magma differentiation in creating intermediate to felsic rocks, and the geochemical analysis using oxygen and hafnium isotopes which indicate the presence of water on Earth's surface over 4 billion years ago. The episode also explores the scientific debates surrounding these ancient minerals and their implications for our understanding of early Earth's geological history.
