Figure F12. Photomicrographs of clinopyroxene (Sample 209-1274A-8R-1, 15-18 cm). A. Clinopyroxene-spinel symplectite at the contact between protogranular orthopyroxene and olivine. The symplectite extends into the olivine (cross-polarized light; field of view = 2.75 mm; image 1274A_049). B. Close-up showing that the clinopyroxene is a single crystal with undulatory extinction (cross-polarized light; field of view = 1.4 mm; image 1274A
