In this episode, we hear from Brian Upton, Emeritus Professor of Geology at the University of Edinburgh, about starting out in South Greenland with the Geological Survey of Greenland in 1955, and what became a lifelong passion for researching and understanding the unique rare earth element-rich rocks of the Gardar Province, on which Brian would become a world expert, still publishing his research on their remarkable geology more than 60 years later.
