Figure F7. Downhole lithologic distributions in Hole 1268A are shown as percentages for each section (left panel) and as volume percent recovery. The lithologies are grouped as dunites (rocks with 90% olivine), harzburgites (includes all ultramafic rocks exclusive of dunites, but the bulk are harzburgites in the strict sense), gabbros (includes gabbronorites, microgabbros, and gabbroic rocks of undeterminable mineralogy), and breccias (mixtures of highly altered, probably originally gabbroic material and ultramafic host). TD = total depth.
