COMING UP:

ASPECT HACKATHON

First two weeks of July, online Hackathon

At the starts of July, Project Manager Ágnes Király, together with project partners and ASPECT developers Juliane Dannberg, Rene Gassmoeller, and Menno Fraters,  will participate at a two weeks workshop aiming to work on new developments for ASPECT. We will work on a material model that can calculate anisotropic viscosity from olivine textures stored on particles that advected with the mantle in Geodynamic simulations.We hope that this wtwo weeks will be a great boost for the start of ANIMA.

Project objectives

Our primary goal is to evaluate the importance of anisotropic viscosity and olivine texture development for multi-scale geodynamic processes.

Secondary objectives:

  • Implementing anisotropic viscosity and texture development within a 3D mantle flow model.

  • Understanding how anisotropic viscosity and olivine texture interact to affect plate motions.

  • Constraining anisotropic viscosity for subduction, and relate this to seismic anisotropy observations.

  • Determining how frozen anisotropy in the lithosphere affects subduction initiation and slab deformation.
