A review of the current understanding of seismic shear-wave splitting in the Earth’s crust and common fallacies in interpretation (2008, background): “Such media include propagation in finely-layered sedimentary sequences in hydrocarbon exploration surveys [59-61]; shales, clays, mudstones, where pore-space is typically constrained between horizontal platelets frequently of mica aligned during deposition [62,63]; and horizontal”
Nonlinear rock physics model for estimation of 3D subsurface stress in anisotropic formations: Theory and laboratory verification (2004, background): “…seismic signatures are more conveniently described in terms of the Thomsen anisotropic coefficients rather than stiffness tensors (Thomsen, 1986; Tsvankin, 2001), we develop the weak-anisotropy approximation that expresses the Thomsen parameters as function of stress magnitudes and the…”
On anelliptic approximations for qP velocities in VTI media (2004, background): “In this type of medium, the phase velocities of qSH-waves and the corresponding wavefronts are elliptic, while the phase and group velocities of qP- and qSV-waves may exhibit strong anellipticity (Tsvankin 2001).”
