Geology Seminar - Diamond: A unique record of Earth's plate tectonic cycle. Graham Pearson, University of Alberta, Canada

Much of the temporal record of Earth’s evolution, including its trace of plate tectonics, is blurred due to the dynamic nature of the crust-mantle system. While zircon provides the highest fidelity crustal record, diamond takes over in the mantle as the go-to mineral, capable of retaining critical information for a variety of geochemical proxies, over billion year timescales. The talk will highlight the unique record of plate tectonics provided by diamond, through the Earth's lithosphere and into the lower mantle, as well as showing gratuitous images of the world's most expensive gemstone.
