Figure F61. Photomicrographs of oxide gabbronorites from 1270B. Ox = oxides, Pl = plagioclase, Opx = orthopyroxene, Cpx = clinopyroxene. A. Oxide-filled, wedge-shaped crack in idiomorphic plagioclase (Sample 209-1270B-10M-2, 53–59 cm) (cross-polarized light [XPL]: blue filter; field of view [FOV] = 5.5 mm; image 1270B_047). B. Wedge of oxide filling a crack in a broken, tabular orthopyroxene grain (Sample 209-1270B-1R-1, 90–93 cm) (XPL: blue filter; FOV = 5.5 mm; image 1270B_014). C. Magmatic oxide enclosing and forming tails on a rolled pyroxene porphyroclast in a matrix of recrystallized plagioclase (Sample 209-1270B-10M-2, 53–56 cm) (plane-polarized light [PPL]: blue + dark gray filters; FOV = 5.5 mm; image 1270B_048). D. Distributed oxide in undeformed oxide gabbronorite (Sample 209-1270B-10M-1, 21–23 cm) (plane-polarized light: blue + dark gray filters; FOV = 5.5 mm; image 1270B
