Figure F151. A. Olivine with subgrain boundaries (Sample 304-U1309B-11R-1, 98–100 cm) (cross-polarized light; field of view [FOV] = 4 mm). B. Lattice-preferred orientation in olivine (Sample 304-U1309B-11R-1, 98–100 cm). Angle to extinction of fast direction (rotation counterclockwise from vertical) in the crystal is plotted versus number of occurrences (N = 34). C. Olivine grains in wehrlite showing common extinction behavior as compared to the harzburgite in Hole U1309B (Sample 304-U1309D-10R-1, 91–94 cm) (cross-polarized light; FOV = 8 mm). D. Olivine in troctolite showing well-defined deformation lamellae (Sample 304-U1309D-70R-3, 86–88 cm) (cross-polarized light; FOV = 4 mm).
