Figure F64. Photomicrographs showing oxide layers in Hole 1270B oxide gabbronorite (Sample 209-1270B-1R-1, 90–93 cm); Ox = oxide, Pl = plagioclase, Cpx = clinopyroxene, Opx = orthopyroxene. A. Oxide lens in recrystallized plagioclase, adjacent to a rolled clinopyroxene augen with tails consisting of agate neoblasts partially cemented by magmatic oxides (cross-polarized light: blue + dark gray filters; field of view [FOV] = 5.5 mm; image 1270B_052). B. Same view as A (plane-polarized light: blue + dark gray filters; FOV = 5.5 mm; image 1270B_051). C. Anastomosing oxide foliation in recrystallized plagioclase, suggesting multiple generations of deformation and oxide crystallization (plane-polarized light: blue + dark gray filters; FOV = 5.5 mm; image 1270B
