Figure F3. Downhole data obtained prior to Expedition 340T, Hole U1309D. A. Lithology is dominantly gabbroic with intervals of olivine-rich troctolite. B. Alteration of core pieces documented during Expedition 304/305 shipboard visual description. C. Density: red = logged, black dots = shipboard core sample. D. Logs of wall rock resistivity. E. P-wave velocity: red = log, black dots = core sample at room temperature/pressure. F. Expanded lithology in upper 800 m where seismic data existed prior to Expedition 340T.
