Timescales for the evolution of seismic anisotropy in mantle flow
E Kaminski, NM Ribe - Geochemistry, Geophysics, Geosystems, 2002 - Wiley Online Library
We study systematically the relationship between olivine lattice preferred orientation and the
mantle flow field that produces it, using the plastic flow/recrystallization model of Kaminski
and Ribe [2001]. In this model, a polycrystal responds to an imposed deformation rate tensor
by simultaneous intracrystalline slip and dynamic recrystallization, by nucleation and grain
boundary migration. Numerical solutions for the mean orientation of the a axes of an initially
isotropic aggregate deformed uniformly with a characteristic strain rate show that the lattice …

Time Scales for the Evolution of Seismic Anisotropy in Mantle Flow
N Ribe, E Kaminski - AGU Fall Meeting Abstracts, 2001 - ui.adsabs.harvard.edu
We study systematically the relationship between olivine lattice preferred orientation (LPO)
and the mantle flow field that produces it, using the plastic flow/recrystallization model of
Kaminski & Ribe,[2001]. In this model, a polycrystal responds to an imposed deformation
rate tensor by simultaneous intracrystalline slip and dynamic recrystallization, by nucleation
and grain boundary migration (GBM). Numerical solutions for the mean orientation Φ of the
fast (a) axes of an initially isotropic aggregate deformed uniformly with a characteristic strain …
