In this podcast episode, Dr. Jesse Reimink and Chris Bolhuis delve into part two of their discussion on Earth's oldest rocks, specifically the Acasta Gneiss. They explore the origin, complex history, and significance of these ancient rocks, including insights from Dr. Reimink's PhD research which suggests an Icelandic rather than subduction zone setting for their formation. The conversation covers the challenges of studying such remote and deformed rocks, the iterative process of geological fieldwork, and the ongoing debates about their exact ages. They also discuss the logistical difficulties of accessing the Acasta Gneiss and the commercialization of samples.Access this episode with images, and more, in the CampGeo app - download now at the link below!Download the CampGeo app now at this link.
