Figure F2. Lithostratigraphic variations in Hole 735B including the core recovered during Legs 118 and 176. A. Relative abundances of rock types averaged over 20 intervals. Lithologic boundaries of Units VII through XII of Leg 176 are shown together with those of Units I through VI of Leg 118 (in italics). Cross-hatched area indicates the extent of a large crystal-plastic shear zone. Troctolitic gabbro encompasses both troctolites and troctolitic gabbro. Oxide gabbro combines oxide gabbro, oxide olivine gabbro, and oxide troctolitic gabbro. Gabbronorite includes orthopyroxene-bearing gabbro and gabbronorite, and orthopyroxene-bearing oxide gabbro and gabbronorite. B. Occurrence of intervals of pegmatitic gabbro. C. Occurrence of microgabbro. D. Occurrence of igneous layering.
