![71.1 Mylonite zone in metaquartzarenite. Grandfather Mountain, North Carolina. Zone in upper right is mylonite derived from metamorphosed quartz arenite in lower left. Dark, microscopic, recrystallized grains of quartz and feldspar mixed in with chlorite and white mica in the mylonite surround syntectonically recrystallized lenses and bands of white to gray quartz and light pinkish-gray alkali feldspar. On the far right, a glassy-gray fragment of a quartz vein is surrounded by mylonitic materials. On the lower left, gray to white grains of quartz and pinkish-gray alkali feldspar with a recrystallized matrix of silvery-white, white mica and green to black chlorite, plus a few iron oxide grains, constitute the meta-sandstone.
