The Past Planet Puzzle

Inaugural Lecture by Professor Alan Collins, ARC Future Fellow and Director, Centre for Tectonics Resources and Exploration (TRaX)

Earth between a billion and 500 million years ago was the cradle of life. Within it, complex creatures evolved and split into all the present phyla, oxygen levels increased and the climate went berserk. This was a pivotal time in Earth history, and tectonic geography is, in some way, responsible for all these phenomena. Yet, despite this, we’re only just getting a handle on what the world looked like back then.

In this Inaugural Lecture, Professor Alan Collins looks at how we can reconstruct the past geography of the planet by using the evidence in the roots of ancient mountain ranges, and start piecing together the past planet puzzle.
