Figure F170. A. Deformed oxide band cutting through a medium-grained gabbro (interval 305-U1309D-183R-2, 21–45 cm). Yellow box = location of B and C. B. Sheared oxide band in contact with the medium-grained gabbro (Sample 305-U1309D-183R-2, 32–34 cm) (plane-polarized light; field of view [FOV] = 2 cm). C. Same as B; cross-polarized light. Yellow box = location of D. D. Highly sheared oxide band (cross-polarized light; FOV = 11 mm). Porphyroblasts of clinopyroxene (Cpx) + plagioclase (Plg) are seen. (Continued on next page.)
