Abstract
H042 The Low and High Frequency Limits for Anisotropic Parameters in a Layered Medium M.B.C. Silva* (Norwegian University of Science & Technology) & A. Stovas (Norwegian University of Science & Technology) SUMMARY The aim of this work is to investigate the relationship between the layer-induced anisotropic parameters from a two layer isotropic medium when calculated in the low frequency limit (by Backus averaging) and in the high frequency limit (from the PP ans SS traveltime parameters). It shown that the effective medium from both PP and SS traveltime parameters computed from a two layer isotropic medium is not exactly a
