Short summary

Grain size is a key factor for deformation. Quartz is one of the main constituents of the crust, but little is known about grain growth that can change grain size. We therefore experimentally determined grain growth laws for quartz. We discuss the importance of the grain size exponent, water fugacity exponent, and activation energy. Our results indicate that the contribution of grain growth to deformation may become important in lower-crustal conditions.
