DI017:
The nature of mantle flow and its role in Earth’s thermal and chemical evolution





Session ID#: 25659

Session Description:
Mantle flow plays a crucial role in Earth’s thermal and chemical evolution. It is responsible for secular cooling of the Earth, the creation and destruction of mantle chemical heterogeneity, and the distribution of dynamic topography. This session aims to better constrain the nature of mantle flow, and invites contributions from (1) seismic observations and constraints of flow features; (2) laboratory experiments on physical properties that control mantle flow; (3) geodynamic modeling that connects surface observables to deep mantle structure; (4) geochemical constraints on the preservation and/or destruction of heterogeneity associated with mantle flow; and (5) all studies that use surface observations, novel data collection, and visualization techniques to understand deep mantle flow. Specific topics include, but are not limited to, dynamics of mantle plumes and influences on hotspot motion, seismic imaging and mantle flow, long-wavelength mantle flow and supercontinent cycles, flow induced surface topography, and tomography-based simulations of mantle flow.
