Quartz grains are elongated approximately 2:1, oblique to the mica foliation, consistent with top-to-the-right (south) sense of shear. In mica-poor layers, quartz recrystallized grain size is larger. Small and isolated white mica grains have pinned quartz grain boundaries, and grains boundaries appear to have moved in windows bewteen adjacent mica flakes; these microstructures suggest that recrystallization occurred at least partly by grain-boundary migration; dislocation creep regime 3.
