Seminar: Slab Driven Lithosphere-Asthenosphere Decoupling in Subduction Zones
The G&T seminar series have a great seminar coming up. Margarete Jadamec from the State University of New York at Buffalo will present her work on Wednesday, April 21st at 11:00am EDT (3pm UTC and 4pm BST/GMT).
The coupling of lithospheric plates to the asthenosphere plays a major role in the process of plate tectonics. However, the nature of this coupling, in terms of asthenospheric viscosity magnitude, spatial variability in viscosity, as well as what drives that variability in space and time, remain outstanding questions in geodynamics. Two-dimensional and three-dimensional numerical simulations of subduction are presented to shed light on this process. Specifically, the models examine the effect of slab geometry, non-linear mantle rheology, and plate interface properties on predicted flow velocities and dynamically emergent asthenospheric viscosity. In addition, this seminar will address how frameworks from the computational fluid dynamics community can facilitate digital scholarship and online learning.
