Figure F154. A. Crystal-plastic deformation in gabbro (interval 304-U1309B-8R-1, 46–50 cm) (field of view [FOV] = 14 cm). B. Well-defined mylonite in gabbro cut by a fracture (Sample 304-U1309D-8R-1, 68–71 cm) (plane-polarized light; FOV = 2 cm). C. Mylonite (Sample 304-U1309D-8R-1, 68-71 cm) (cross-polarized light; FOV = 8 mm). D. Same as C; recrystallized plagioclase and pyroxene (plane-polarized light; FOV = 1 mm). E. Brown amphibole vein crosscuts highly localized shear zone in a mylonite with domains of recrystallized plagioclase and pyroxene (Sample 304-U1309D-9R-1, 71–73 cm) (cross-polarized light; FOV = 4 mm). F. Annealed microcracks in feldspar (Sample 304-U1309B-9R-1, 38-41 cm) (plane-polarized light; FOV = 4 mm).
