Figure F17. Photomicrographs showing clinopyroxene and orthopyroxene relationships. A. Clinopyroxene-filled triple junction between orthopyroxene crystals (Sample 209-1272A-27R-1, 123–126 cm) (cross-polarized light [XPL]: blue filter; field of view [FOV] = 1.4 mm; image 1272A_020). B. Smoothly curved contact between two orthopyroxenes with intergranular clinopyroxene (pointed by an arrow); a clinopyroxene lamellae (outlined in white) grew in the left orthopyroxene (Sample 209-1272A-18R-1, 46–48 cm) (XPL: blue filter; FOV = 0.7 mm; image 1272A_017). C, D. Sample 209-1272A-17R-1, 127–129 cm; (C) clinopyroxene at an orthopyroxene grain boundary (XPL; FOV = 0.7 mm; image 1272A_018); (D) clinopyroxene at an orthopyroxene grain boundary (XPL: blue filter; FOV = 1.4 mm; image 1272A
