Figure F14. Compressional wave velocities vs. depth in Holes 1224D, 1224E, and 1224F. Seven depth zones are introduced, as seen on the far right. Compressional wave velocities in the three holes have similar depth dependence between 27 and 53 mbsf. Zones 1 and 2 correspond to logging Unit I (Fig. F15), Zone 3 corresponds to logging Unit II, Zone 4 corresponds to logging Unit III, Zones 5 and 6 correspond to logging Unit IV, and Zone 7 corresponds to logging Unit V.
