Radial seismic anisotropy as a constraint for upper mantle rheology (2007, methodology): “However, our LVV flow model may serve as a first guess for “realistic” mantle flow fields, and leads to a better plate-tectonic fit than models without LVVs (Becker, 2006).”
Global plate motion frames: Toward a unified model (2008, background): “…large-scale mantle flow models are becoming more realistic because of inclusion of temperature-dependent and strain rate–dependent viscosities [e.g., Becker, 2006; Čadek and Fleitout, 2003] and further constraints, in particular related to seismic anisotropy [e.g., Becker et al., 2006; Behn et…”
Constraints on lithosphere net rotation and asthenospheric viscosity from global mantle flow models and seismic anisotropy (2010, methodology): “e Net rotation Euler pole reported by Becker [2006] .”
On the relationship between azimuthal anisotropy from shear wave splitting and surface wave tomography (2012, background): “…mapped azimuthal or radial anisotropy resides in the asthenospheric regions above 300 km, where formation of LPO anisotropy for olivine in the dislocation-creep regime can be quantitatively linked to anisotropy [Podolefsky et al., 2004; Becker, 2006; Becker et al., 2008; Behn et al., 2009].”
A benchmark study on mantle convection in a 3‐D spherical shell using CitcomS (2008, methodology): “In particular, the net rotation of lithosphere has implications for the reference frame of plate motion [e.g., O’Connell et al., 1991; Forte and Peltier, 1994; Zhong, 2001; Becker, 2006 ] and seismic anisotropy [Becker, 2008].”
Tectonic speed limits from plate kinematic reconstructions (2015, background): “…viscosity beneath oceanic lithosphere at least one order of magnitude lower than the viscosity of the asthenosphere beneath continents (Ricard et al., 1991), suggesting that purely oceanic plates are more decoupled from the underlying mantle than plates with deep continental keels (Becker, 2006).”
Global mantle flow and the development of seismic anisotropy: Differences between the oceanic and continental upper mantle (2007, background): “[6] Although lateral viscosity variations have been employed in studies that predict lithospheric stresses [Conrad and Lithgow-Bertelloni, 2006], the geoid and dynamic topography [Zhang and Christensen, 1993; C¸adek and Fleitout, 2003], net lithosphere rotation [Zhong, 2001; Becker, 2006 ], and pla”
