53 Seismic anisotropy

2002
This chapter focuses on seismological aspects of seismic anisotropy. It presents results that link the observations of seismic anisotropy to dynamic processes acting in the Earth. Evidence for seismic anisotropy come either from local variation of seismic velocities with respect to the direction of propagation, or from anomalies linked with their ...

A case of anisotropy of seismic velocity

Geoexploration, 1964
Abstract The anisotropy of the seismic velocity at a metamorphic shale was determined by measurements underground in the Langsele mine in the Skelleftea ore district (Sweden). In this paper the results are discussed and compared with a model consisting of a stratified medium with two alternating layers.

Seismic anisotropy and mantle flow

Journal of Geophysical Research: Solid Earth, 1989
Seismic anisotropy in the mantle is primarily due to deformation‐induced lattice preferred orientation (LPO) of olivine crystals. The aim of this paper is to better understand how such LPO is produced by flow, and to learn whether observations of seismic anisotropy can be used to infer the local direction of flow within the mantle.

Stochastic representation of seismic anisotropy

2018
Jordan?s (2015) self-consistent, second-order Born theory is applied to compute the effective stiffness tensor for spatially stationary stochastic models of 3-D elastic heterogeneity. The effects of local anisotropy can be separated from spatially extended geometric anisotropy by factoring the covariance of the moduli into a one-point variance tensor ...
