Figure F2. Simplified core logs for Sites 1268, 1270, 1271, 1272, 1274, and 1275 (detailed lithologic sections are available in Shipboard Scientific Party, 2004a: figs. F7, F21, F31, F37, F42, F50). Based on these data, we infer that the entire area may be underlain by mantle peridotite with ~20%–40% gabbroic intrusions and impregnations, consistent with results of previous dredging and submersible studies.
