Geodynamics of the Yellowstone hotspot and mantle plume: Seismic and GPS imaging, kinematics, and mantle flow (2009, result): “Our observations and models agree well with the "spout" plumes derived by Farnetani and Samuel (2005), who predicted widespread magma ponding beneath the transition zone and only a narrow tail with 120-180 km diameter and 100-150 K excess temperatures.”
Thermal versus elastic heterogeneity in high‐resolution mantle circulation models with pyrolite composition: High plume excess temperatures in the lowermost mantle (2009, background): “…illuminate the dynamic consequences of a dense component in the deep mantle [Hansen and Yuen, 1989, 1994, 2000; Montague and Kellogg, 2000; Davaille et al., 2002; Stegman et al., 2002; Jellinek and Manga, 2004; Nakagawa and Tackley, 2004; McNamara and Zhong, 2004, 2005; Farnetani and Samuel, 2005].”
Dynamics and evolution of the deep mantle resulting from thermal, chemical, phase and melting effects (2012, background): “Farnetani and Samuel (2005) showed that in thermo-chemical convection a great variety of plume shapes and sizes can form simultaneously.”
Tomographic filtering of high‐resolution mantle circulation models: Can seismic heterogeneity be explained by temperature alone? (2009, background): “The large amplitudes of lateral variations in shearwave velocity of up to 3 to 4%, in particular, have been taken to argue for compositional heterogeneity [e.g., Farnetani and Samuel, 2005; Samuel et al., 2005].”
