The behaviour of parabolic lines and caustics in anisotropic solids can be very complicated, but in considerably simplifies under weak anisotropy. Supposing sufficiently weak anisotropy, no parabolic lines appear on the S1 slowness sheet. Consequently, the S1 wave sheet displays no caustics and triplications. Parabolic lines and caustics can appear for the S2 wave.
