Figure F16. Photomicrographs showing olivine and orthopyroxene relationships. A. Smoothly curved olivine/orthopyroxene grain boundary (Sample 209-1272A-27R-1, 50–52 cm) (cross-polarized light [XPL]; field of view [FOV] = 2.75 mm; image 1272A_034). B. Curved orthopyroxene partially enclosing olivine grains at its left border (Sample 209-1272A-13R-2, 33–36 cm) (XPL; FOV = 2.75 mm; image 1272A_033). C. Anhedral, equant orthopyroxene enclosing an olivine grain (Sample 209-1272A-25R-1, 123–126 cm) (XPL; FOV = 5.5 mm; image 1272A_035). D. Orthopyroxene interstitial between four olivine grains (Sample 209-1272A-13R-2, 33–36 cm) (XPL; FOV = 2.75 mm; image 1272A_031). E. Orthopyroxene partially interstitial due to deep olivine embayments (Sample 209-1272A-18R-1, 46–48 cm) (XPL: blue filter; FOV = 2.75 mm; image 1272A
