Figure F15. A. Plot of modal percent clinopyroxene vs. modal percent olivine in Leg 176 samples measured in thin section. B. Plot of modal percent clinopyroxene vs. modal percent plagioclase in Leg 176 samples measured in thin section. Gabbronorite and oxide gabbronorite include orthopyroxene-bearing gabbro and gabbronorite. Orthopyroxene-bearing gabbros and oxide orthopyroxene-bearing gabbros are grouped with gabbronorite and oxide gabbronorite, respectively.
