- •
Experiments simulate stress changes in the middle crust.
- •
Non-steady state microstructures provide accurate information about stress history.
- •
Two-stage experiments create bimodal grain populations similar to many mylonites.
- •
Wattmeter predicts recrystallized grain sizes for many deformation histories.
- •
Outcomes include a simplified quartzite flow law and linear viscosity at high stress.
