Thermal versus elastic heterogeneity in high‐resolution mantle circulation models with pyrolite composition: High plume excess temperatures in the lowermost mantle (2009, background): “The high plume excess temperatures in the deeper mantle agree with tomographic studies showing a depthwise increase in heterogeneity strength of low seismic velocity anomalies [Boschi andDziewonski, 1999; Romanowicz and Gung, 2002;Montelli et al., 2004], and are probably related to independent evide”
Geodynamics of the Yellowstone hotspot and mantle plume: Seismic and GPS imaging, kinematics, and mantle flow (2009, methodology): “Moreover, this model also matches the global tomography model by Montelli et al. (2004) and explains our observations of “blobs” of melt in the transition zone.”
Constraining P-wave velocity variations in the upper mantle beneath Southeast Asia (2006, background): “Other studies have argued for a lower mantle origin of the Hainan structure (e.g., Montelli et al., 2004), but the observations presented here suggest that the most prominent part is confined to the upper mantle and transition zone.”
Seismic imaging: From classical to adjoint tomography (2012, methodology): “2007), hotspots (Montelli et al., 2004) and continental collision zones (M.”
Finite-Frequency Kernels Based on Adjoint Methods (2006, background): “Such kernels were recently implemented for compressional-wave tomography by Montelli et al. (2004).”
Misfit functions for full waveform inversion based on instantaneous phase and envelope measurements (2011, background): “Taking into account finite-frequency effects of wave propagation is the way to potentially improve resolution of tomographic images (e.g. Montelli et al. 2004; Sigloch et al. 2008), but this has to go beyond the use of identifiable phases (Boschi et al. 2007).”
Imaging seismic velocity structure beneath the Iceland hot spot: A finite frequency approach (2004, background): “[3] Tomographic studies have revealed low compressional (P )a nd shear (S) wave speeds beneath Iceland at both regional and global scales [Tryggvason et al., 1983; Wolfe et al., 1997; Bijwaard and Spakman, 1999; Ritsema et al., 1999; Foulger et al., 2000; Zhao, 2001; Allen et al., 2002b; Montelli e”
Anisotropic shear‐wave velocity structure of the Earth's mantle: A global model (2008, neutral): “More complex approximations have been developed and implemented for certain types of data [e.g., Montelli et al., 2004a, 2004b].”
Beyond the thermal plume paradigm (2005, background): “most likely derived from a relatively undegassed mantle source [Farley et al., 1992], and a deep origin is supported by seismic tomography [ Montelli et al., 2004 ].”
Core–mantle boundary heat flow (2008, background): “Some debated seismic tomography models indicate ∼500–1,000 km scale upwellings in the lower mantle beneath some surface hotspot”
Archean Geodynamics and the Thermal Evolution of Earth (2013, background): “It is thus quite surprising that a recent finite-frequency tomography has resolved quite a few deep mantle plumes with very large radii, typically ranging from 200 to 400 km [Montelli et al., 2004].”
Organized melt, seismic anisotropy, and plate boundary lubrication (2010, background): “[20] In the vicinity of the Iceland hot spot and the Reykjanes Ridge (RR), there is strong evidence for both the presence of a deep mantle plume [e.g., Wolfe et al., 1997; Shen et al., 1998;Montelli et al., 2004] and the flow of plume material along the ridge axis [e.”
