Descripción del proyecto The lithosphere is the thin outer shell of the Earth that supports the weight of mountains, plate tectonic forces, and stores the elastic energy that is released during earthquakes. The strength of the lithosphere directly controls the formation of tectonic plates and the generation and propagation of devastating earthquakes. The strongest part of the lithosphere is where the deformation processes in rocks transition from brittle fracture to plastic flow. This transition controls the strength of tectonic plate interfaces, the coupling between mantle flow and surface tectonics, as well as the complex fault slip patterns recently highlighted by geophysical records (e.g., tremors and slow slip). Despite its fundamental importance, the transitional behaviour remains very poorly understood. In this regime, we still do not know how rock deformation processes and properties evolve with depth and, critically, time. We also do not know exactly where the transition occurs in nature, if and how it may move over time, and what are the prevailing conditions there. The aim of this project is to provide unprecedented quantitative constrains on the key material properties and processes associated with deformation and fluid flow at the brittle-plastic transition, and arrive at a clear understanding of the prevailing conditions and the dynamics of fault slip at the transition. I propose to conduct laboratory rock deformation experiments at the high pressure and temperature conditions relevant to the transitional regime, and achieve unprecedented quantitative physical measurements by developing state-of-the-art in-situ instrumentation, taking advantage of the latest sensor technologies. I will focus on quantifying the effects of time and fluids, which are currently unexplored. The ultimate outcome of the project is to detect the transition in nature by understanding its geophysical signature, and constrain the strength of faults and plate boundaries throughout the seismic cycle.
