Figure F60. Photomicrographs of Hole 1270B oxide gabbronorites. Opx = orthopyroxene, Cpx = clinopyroxene, Pl = plagioclase. A–C. Sample 209-1270B-1R-1, 90–93 cm. (A) Plagioclase ribbon porphyroclasts and recrystallized feldspar matrix adjacent to undeformed orthopyroxene (cross-polarized light [XPL]: blue filter; field of view [FOV] = 2.75 mm; image 1270B-036). (B) Spectacularly bent clinopyroxene enclosed in recrystallized plagioclase and late magmatic oxide (plane-polarized light: blue filter; FOV = 5.5 mm; image 1270B_018). (C) Same view as B (XPL: blue filter; FOV = 5.5 mm; image 1270B_016). D. Magmatic oxide enclosing a rolled pyroxene augen, with a fragment of the pyroxene enclosed in the mantling oxide and oxide cementing isolated pyroxene neoblasts in the tail, all enclosed in recrystallized plagioclase (Sample 209-1270B-3M-1, 129–131 cm) (PPL: blue + dark gray filters; FOV = 5.5 mm; image 1270B_050). E. Mat of magmatic oxide enclosing isolated plagioclase and clinopyroxene neoblasts in the tail of a clinopyroxene porphyroclast. Oxide also extends into the enclosing matrix of plagioclase neoblasts (Sample 209-1270B-1R-1, 83–85 cm) (PPL: blue + dark gray + light gray filters; FOV = 2.75 mm; image 1270B_040).
