| Abstract: | Summary. Three problems of seismic anisotropy in thinly layered media (TPM) are discussed: (1) A dependence is established for the character of the ray velocity of longitudinal low-frequency waves on the ratio of P - and S -wave velocities in thin layers. (2) Conditions are specified for cusps on SV -wave surfaces. Nomograms are suggested for quick estimation of these conditions. (3) A comparison is made between TPM anisotropy and other types of transversely isotropic media. |
