Figure F175. A. Dark green vein associated with sheared fractures in gabbro (interval 305-U1309D-277R-2, 64–75 cm). Yellow box = location of B and C. B. Dark green sheared vein (Sample 305-U1309D-277R-2, 69–71 cm) (plane-polarized light, field of view [FOV] = 2 cm). Yellow box = location of D. C. Same as B; cross-polarized light. Yellow box = location of E. D. Fractured plagioclase and clinopyroxene grains that have been intensely bent and fractured along the vein networks (plane-polarized light; FOV = 5.5 mm). E. Same as D; cross-polarized light. (Continued on next page.)
