Figure F77. Photomicrographs of Hole 1270C and 1270D harzburgites showing deformation textures (cross-polarized light; field of view = 5.5 mm). Ol = olivine, Opx = orthopyroxene. A. Protomylonitic harzburgite enclave adjacent to gabbro mylonite veins (Sample 209-1270C-1R-1, 83–85 cm) (image 1270C_028). B. Protogranular orthopyroxene bastite pseudomorph (Sample 209-1270D-3R-1, 94–97 cm) (image 1270D_030). C. Protogranular orthopyroxene bastite showing incipient breakup of grain during porphyroclastic deformation (Sample 209-1270D-6R-1, 29–32 cm) (image 1270D_034). D. Protogranular orthopyroxene bastite broken into two new porphyroclasts (Sample 209-1270D-3R-2, 68–71 cm) (image 1270D_033). E. Orthopyroxene porphyroclast with granulated and crushed pyroxene grains along its mantle (Sample 209-1270C-3M-1, 44–46 cm) (image 1270C_029). F. Orthopyroxene bastite pseudomorph showing internal strain and incipient fracture (Sample 209-1270C-1R-1, 72–75 cm) (image 1270C
