摘要: Summary. The theory, causes, observations, and possible applications of seismic anisotropy in the Earth have developed considerably since previous state art paper was published 1977. behaviour waves layered anisotropic media is now much better understood evidence for indicates that likely to be present throughout crust upper mantle. top few hundred kilometres mantle appears with orientations aligned by or palaeo stress-field. part frequently anisotropic, probably due cracks differentially non-lithostatic stresses. possibility being able monitor crack geometry techniques opens a wide range currently important activities.
