Figure F14. Photomicrograph in cross-polarized and plane-polarized light of an oxide gabbronorite. Shown are large crystals of clinopyroxene (brightly colored on the left), interstitial oxide, orthopyroxene with blue exsolution lamellae of clinopyroxene, and plagioclase (colorless in plane-polarized light). Note the development of neoblasts at the margins of the pyroxene and plagioclase grains (Sample 209-1272A-19R-1, 33–35 cm) (field of view = 5.5 mm). A. Cross-polarized light: blue filter; image 1272A_004. B. Plane-polarized light: blue filter; field of view = 1.4 mm; image 1272A
