Figure F11. Modes of occurrence of oxide-rich gabbros. A. Oxide patches in magmatic texture (Sample 305-U1309D-254R-1, 34–36 cm) (plane-polarized light; field of view [FOV] = 2 cm). B. Same as A; cross-polarized light. C. Oxide-rich shear zone (Sample 305-1309D-183R-2, 32–34 cm) (plane-polarized light; FOV = 2 cm). D. Same as C; cross-polarized light.
