Abstract

In all rocks investigated (peridotite, amphibolite, serpentinite, marble) the observed seismic anisotropy is primarily a consequence of preferred orientation of minerals and of the elastic anisotropy of the constituent minerals of the rocks. Generally the compressional-wave velocity decreases with temperature. The amount of velocity decrease, however, is different in the various rock types and even for different directions in the same anisotropic media. Fabric-induced seismic anisotropy is not drastically reduced with temperature. In the amphibolite, and especially in the serpentinite seismic anisotropy even increases with temperature. It is expected that the preferred orientation of minerals may have an effect on wave propagation even at great depths in the earth's crust and in the upper mantle.
