Figure F33. A. Plot showing relationship between predicted depths to key horizons and sequence boundaries (dashed) and corrected depths (arrowed) for Site 1130. Corrected depths are based on the check-shot survey data (heavy solid line), shown plotted immediately below the envelope of stacking velocity curves (derived from six common depth points from site-survey seismic data immediately adjacent to this site). The integrated sonic log, based on interval transit time data, is plotted as a heavy dashed line. B. Interval velocities derived from the eight check-shot stations are shown overlying the velocity log (derived from the compressional sonic trace).
