Title: Inside Out: How the Interior Shapes the Surface
Abstract: Elucidating the present and past dynamics of Earth’s interior are fundamental to understanding the surface, from plate motions to major and trace element geochemistry. I review my efforts to date to marry the dynamics of the mantle to the geological record An initial focus on understanding present-day motions, deformation and topography is now coupled with a look at Earth’s secular evolution. Specifically, how the physical properties of mantle minerals lead to a dynamical evolution that may explain geochemical observations, from the preservation of primitive reservoirs to large thermal pulses and continental formation in the Early Earth.
Intellectual Engagement: Speakers have been asked to prepare a 50-minute presentation and to reserve 10 minutes for questions and answers. During the first 50 minutes, brief requests for clarifications will be allowed. Substantive questions should be confined to the Q&A period. A moderator will manage the order of questions starting at the 50-minute mark. Questions related to the speaker's presentation will take priority over other comments.
