Figure F8. A. Boundary between olivine (Ol) gabbro (Interval 59) and troctolite (Interval 58), Unit II (Sample 345-U1415J-10R-1, 39–55 cm [Piece 6B]). B, C. Large poikilitic clinopyroxene (Cpx) that is larger than the width of the thin section and optically continuous throughout, forming the interstitial clinopyroxene in the troctolite of Interval 58 (dashed pink line marks the boundary of this oikocryst). Dashed red line in C marks the boundary between lithologies (Thin Section 58). B is under plane-polarized light and C is under crossed polars. (Ol) = altered olivine, Pl = plagioclase. See also Figure F10.
