Figure F344. Velocity-depth plot of Hole 1256D showing wireline sonic and check-shot interval velocities from Expedition 312 and Leg 206. Bulk density data from Hole 1256D are also shown. The increase in velocity in the sheeted to granoblastic dike boundary to values around 7.0 km/s is apparent. HLDS = Hostile Environment Litho-Density Sonde.
