Short summary
Modeling natural deformation requires a good understanding of how the microscale and mesoscale properties of rocks affect bulk deformation. However, describing strain accommodation at a range of scales during rock deformation is an experimental challenge. We developed a novel technique that allows us to map strain down to the microscale. This technique was successfully applied to high-pressure, high-temperature deformation experiments and could be applied to a wide variety of geomaterials.
