Geomechanical (Engineering) Properties...

Seismic velocities can be related to standard geotechnical properties. For example, Poisson's ratio n can be found from:

Figures 1 and 2 show the S and P wave velocities of seismic waves for a number of different rock types.

Figure 1.  S-wave velocity ranges for common materials.

Figure 2.  P wave velocity ranges for common materials.
