Figure F79. Downhole modal variation in Hole U1309D. A. Olivine. B. Oxide. C. Pyroxenes, including both clinopyroxene and orthopyroxene. D. Orthopyroxene. Data from visual core description except for orthopyroxene, for which modes were estimated from thin section (TS) observation. Olivine and oxide modal amounts correspond to lithologic variation in the stratigraphic column. Pyroxene mode is relatively constant, except for the olivine-rich troctolite interval. Orthopyroxene is distributed in almost the entire hole and modal amount varies related to total pyroxene mode variation.
