Seismic anisotropy and mantle creep in young orogens
R. Meissner, Thomas C. Mooney, I. Artemieva
2002, Geophysical Journal International (149) 1-14
Seismic anisotropy provides evidence for the physical state and tectonic evolution of the lithosphere. We discuss the origin of anisotropy at various depths, and relate it to tectonic stress, geotherms and rheology. The anisotropy of the uppermost mantle is controlled by the orthorhombic mineral olivine, and may result from ductile...
