Seismic observations of large-scale deformation at the bottom of fast-moving plates (2012, background): “The anisotropy predicted by the geodynamic model of Kaminski et al. (2004) seems also to be rapidly uniform in the asthenosphere and the lithosphere.”
Joint seismic-geodynamic-mineral physical modelling of African geodynamics: A reconciliation of deep-mantle convection with surface geophysical constraints (2010, methodology): “D flow patterns, Kaminski and Ribe (2002) considered the necessary conditions for the alignment of LPO with the flow direction and they derived a local dimensionless ‘grain orientation lag’ parameter, Π, that can be used to quantify the degree to which this alignment obtains.”
D-Rex, a program for calculation of seismic anisotropy due to crystal lattice preferred orientation in the convective upper mantle (2004, methodology): “Kaminski & Ribe (2002) showed that olivine LPO in the mantle will follow the convective flow direction only if the time required for the crystals to reach a steady-state LPO is smaller than the timescale over which the deformation varies along a pathline.”
Global mantle flow and the development of seismic anisotropy: Differences between the oceanic and continental upper mantle (2007, methodology): “: SEISMIC ANISOTROPY AND MANTLE FLOW 12 of 17 B07317 approximation for LPO in most locations [Kaminski and Ribe, 2002].”
Shear Wave Splitting and Mantle Anisotropy: Measurements, Interpretations, and New Directions (2009, background): “This approach, however, ignores possible complexities such as olivine fabric transitions and does not realistically model the development of LPO or take into account the timescale over which LPO develops (Kaminski and Ribe 2002).”
Statistical properties of seismic anisotropy predicted by upper mantle geodynamic models (2006, unknown): “The KR method addresses a range of laboratory findings for LPO development [Kaminski and Ribe, 2002].”
Effect of water and stress on the lattice-preferred orientation of olivine (2006, background): “Obviously non-steady-state fabric could occur in nature, and the time scale to modify the pre-existing fabrics is an important issue particularly in regions where dominant fabric types are expected to change spatially (e.g., subduction zones; Kaminski and Ribe, 2002).”
