A cross-plot of average compressional- versus average shear-wave velocities with isolines for Vp/Vs ratio of different common minerals. The compressional and shear wave velocities for such minerals were after (1) Carmichael (1990), (2) Humbert and Plicque (1972), (3) Chen et al. (2001). (B) Clusters of rock-types based on the plotting of the seismic velocity ratio vs. the compressional-wave velocity. Similar clustering pattern was found for shear-wave velocity. Error bars are within symbols
