Short summary

We examine rocks from the middle crust to explore how fluids circulate and influence a rock’s response to larger-scale tectonic movements. A model is developed in which fluids deep in the Earth migrate to clusters of pores generated during those movements. We document how distinct pores form in a specific order in association with local changes in how quartz deforms. The porosity evolves out of the deformation, changing the rate the rock moved under tectonic forces.
