Figure F53. Summary of logs from Pass 2 of the Formation MicroScanner (FMS)-sonic tool string and logging units, Hole U1417E. Hole size is measured by the two orthogonal calipers of the FMS (C1 and C2). Waveform coherence in the velocity tracks is a measure of the reliability of the slowness/time coherence algorithm used to derive compressional (VP) and shear (VS) velocities from monopole and lower dipole sonic waveforms, respectively. Particularly below ~305 m WMSF, VP shows similar trends to resistivity.
