Figure F19. Boundary between gabbronorite and clinopyroxene (Cpx) oikocryst-bearing troctolite (red dashed lines) (Thin Section 40; Sample 345-U1415J-7G-1, 26–34 cm [Piece 5]). Boundary type = grain size and modal; boundary definition = sutured. A. Core close-up. B. Plane-polarized light. Ol = olivine, Opx = orthopyroxene, Pl = plagioclase. C. Under crossed polars.
