  "term": "Gamma (γ)",
  "field": "Oil and gas",
  "definition": "The Thomsen parameter for shear-wave anisotropy in a transversely isotropic medium with a vertical symmetry axis. It is approximately the fractional difference between the velocity of horizontally traveling SH waves, which move along the layering, and that of vertically traveling shear waves, and a value of zero means shear velocity does not depend on direction. With epsilon and delta it makes up the three Thomsen parameters.",
