Abstract Scope All around us, things are constantly plastically deforming, whether it be at nanoscale atomic level in metallic alloys to the km-scale during geological flow in the lithosphere. We will present cross-cutting theories on the nature of pressure and shear-driven structural evolution in metals and geological materials. Novel solid-phase material deformation methods and in-situ beamline studies will reveal metallic deformation pathways that will be directly compared to the current earth science literature on ductile deformation in rocks. The finding forecast the ability to use laboratory scale tools and simulant materials to extend our understanding of how the world has moved underneath us and how it may deform in other parts of the universe.
