Electron Backscatter Diffraction (EBSD) orientation maps showing deformation textures in mylonite from the Cordillera Blanca Detachment fault system in the Peruvian Andes. In the maps quartz grains used in the analysis are color-coded according with inverse pole figure (IPF) color scheme shown in top left of figure. IPF colors indicate the crystal direction vector that is parallel to the vertical edge of the map (y-direction). Pixels with gray scale coloring were excluded from the analyzed set. The upper panels highlight large relict quartz grains with highly distorted lattices while the lower panels highlight dynamically recrystallized grains with low internal strain. Horizontal field of view is approximately 275 microns.
