A benchmark study on mantle convection in a 3‐D spherical shell using CitcomS (2008, methodology): “[74] An earlier study using CitcomS for thermochemical convection focused on the accuracy of tracer advection algorithm and conservation of total composition [McNamara and Zhong, 2004].”
The primitive nature of large low shear-wave velocity provinces (2012, background): “Meanwhile, experimental (Davaille, 1999; Le Bars and Davaille, 2004) and numerical (Tackley, 2002; McNamara and Zhong, 2004; Tan and Gurnis, 2007; Deschamps and Tackley, 2008, 2009) models of thermo-chemical convection including an initial layer of dense material showed that reservoirs of dense…”
Thermal versus elastic heterogeneity in high‐resolution mantle circulation models with pyrolite composition: High plume excess temperatures in the lowermost mantle (2009, background): “[49] An important argument in support of chemical heterogeneity is the morphology, or shape, of deep mantle upwellings, taken either from direct observations of seismic data [Ni et al., 2002], or from laboratory [Jellinek and Manga, 2004] and numerical studies [McNamara and Zhong, 2004].”
LINKS BETWEEN LONG‐LIVED HOT SPOTS, MANTLE PLUMES, D″, AND PLATE TECTONICS (2004, methodology): “…mantle convection are typically limited to two dimensions [e.g., Christensen, 1984b; Montague and Kellogg, 2000; Farnetani, 1997; McNamara and Zhong, 2004a], though three-dimensional simulations are currently being performed [e.g., Tackley, 2002; Tackley and Xie, 2002; McNamara and Zhong, 2004b].”
On the statistical distribution of seismic velocities in Earth's deep mantle (2008, background): “Dynamic models of thermochemical convection (Tackley, 1998; Davaille et al., 2003; McNamara and Zhong, 2004) have all shown how a laterally discontinuous and compositionally dense layer can increase heterogeneity at the base of the mantle when the underlying CMB is isothermal.”
Convective patterns under the Indo-Atlantic « box » (2005, background): “Numerical calculations are shown in grey [87], light blue [66], brown [88,89], purple [90], green [91] and pink [ 92 ].”
Dynamics and evolution of the deep mantle resulting from thermal, chemical, phase and melting effects (2012, background): “Numerical results, however, found little difference in the fixity of thermo-chemical plumes and purely thermal plumes (McNamara and Zhong, 2004a).”
Constraints on thermochemical convection of the mantle from plume heat flux, plume excess temperature, and upper mantle temperature (2006, methodology): “…significant effects on the dynamics of the mantle, as demonstrated by studies on heat transfer and mantle structure for a compositionally heterogeneous or layered mantle [Davaille, 1999a, 1999b; Tackley, 1998, 2002; Kellogg et al., 1999; Jellinek and Manga, 2002; McNamara and Zhong, 2004, 2005].”
