20: Allen Nutman: “What if the boundary is folded?” – figuring out the structure of Earth’s ancient crust

Update: 2020-11-10

Description

In this episode, we hear more from Allen Nutman, Professor of Geology at the University of Wollongong in Australia, about how his mapping work together with Vic McGregor and Clark Friend led to the beginnings of a model for how the ancient rocks in the Nuuk region were formed as a series of distinct small continents that collided with each other about 2.7 billion years ago.
