... the seismic anisotropy using a foliated and a non-foliated granite rock. We measure both velocities and attenuations with increasing confining pressures from 5 to 50 MPa in ultrasonic frequency bands. As the confining pressure increases, the results demonstrate significant increases in P-wave velocity and S...

However, wet till sequences generally exhibit the highest losses with meta-volcanic bedrock also exhibiting higher attenuation rates than granites. Relative permittivity contrasts...
