Compressional and shear velocities, density, and porosity were measured for 22 serpentinized peridotites recovered during ODP Leg 125. The densities of the samples vary from 2.40 to 2.86 g/cm**3, whereas the compressional velocities at 200 MPa are between 4.60 and 6.47 km/s. A positive linear trend exists between both compressional and shear velocities and density. The high porosity in serpentinized peridotites decreases the density and seismic velocity.
