Sonic velocities are consequently lower (for propagation directions normal to mylonite foliation) than in surrounding unmylonitized rocks. Synthetic seismograms computed for low-velocity, near-horizontal, thick mylonite zones of complex, laminated geometry show multicyclic reflections with amplitudes up to twice those generated by a single interface. Seismic characteristics of mylonite zones are sufficient to produce reflections in crystalline rocks, provided noise levels are relatively low. This content is PDF only.
