Integrated geophysical‐petrological modeling of the lithosphere and sublithospheric upper mantle: Methodology and applications (2008, methodology): “The thermodynamic database we use here [Stixrude and Lithgow-Bertelloni, 2005a] does not account for Cr2O3, but it predicts plagioclase-spinel-garnet phase transitions that are consistent to a first order with experimental data on natural peridotites with a wide range of compositions [e.g., Green…”
Tomographic filtering of high‐resolution mantle circulation models: Can seismic heterogeneity be explained by temperature alone? (2009, methodology): “…by postprocessing the present day temperature field obtained from mantle circulation models with one of the aforementioned thermodynamic mineralogical models, which includes all the effects of phase changes in a 5-oxide (CFMAS) pyrolitic composition [Stixrude and Lithgow-Bertelloni, 2005, 2007].”
Thermal versus elastic heterogeneity in high‐resolution mantle circulation models with pyrolite composition: High plume excess temperatures in the lowermost mantle (2009, methodology): “…the corresponding reduction in shear wave velocity of up to 4%, which we infer using published models of mantle mineralogy [Piazzoni et al., 2007; Stixrude and Lithgow-Bertelloni, 2005, 2007], agrees remarkably well with shear wave anomalies mapped in low seismic velocity regions of the deeper…”
The influence of MORB and harzburgite composition on thermo-chemical mantle convection in a 3-D spherical shell with self-consistently calculated mineral physics (2010, methodology): “…properties, including elastic moduli, are computed as a function of pressure and temperature with the Perple_X free energyminimization program (Connolly, 2005) using the data of Xu et al. (2008), which is based on the thermodynamic formulation of Stixrude and Lithgow-Bertelloni (2005).”
The composition of Mars (2019, result): “d FeO (Lee and Gaskell, 1974; Komabayashi, 2014) and solid FeH (Umemoto and Hirose, 2015) at core pressures and temperatures and a third-order ﬁnite strain Birch-Murnaghan or Vinet equation of state (Stixrude and Lithgow-Bertelloni, 2005), following previous studies (Longhi et al., 1992; Sohl and Sp”
Thermodynamics of silicate liquids in the deep Earth (Invited) (2009, background): “This approximation was motivated, at least in part, by the behavior of mantle crystalline phases, which show values of q that in many cases are indistinguishable from unity, and that in all cases are positive (Stixrude and Lithgow-Bertelloni, 2005).”
Thermodynamics, structure, dynamics, and freezing of Mg2SiO4 liquid at high pressure (2008, methodology): “of periclase + MgSiO3 liquid (Stixrude and Karki, 2005), and solid phase assemblages perovskite + periclase (Pv + Pe), post-perovskite + periclase (PPv + Pe) and stishovite + periclase (St + Pe) ( Stixrude and Lithgow-Bertelloni, 2005 ), to the published high-pressure shock data for forsterite and w”
The MgSiO3 system at high pressure: Thermodynamic properties of perovskite, postperovskite, and melt from global inversion of shock and static compression data (2009, methodology): “This distinguishes our modeling from previous global inversion efforts in which more parameters were fixed [Bina, 1995; Jackson and Rigden, 1996; Shim and Duffy, 2000; Stixrude and Lithgow-Bertelloni, 2005 ].”

The geodynamic equation of state: What and how (2009, methodology): “In principle, this inconsistency can be resolved by formulating an equation of state in terms of the elastic deviatoric strain tensor in addition to the specific volume, which is used to characterize mechanical state in the hydrostatic case [Callen, 1960; Stixrude and Lithgow-Bertelloni, 2005 ].”
Reconciling dynamic and seismic models of Earth's lower mantle: The dominant role of thermal heterogeneity (2012, methodology): “…parameters using lookup tables (pers. comm. Stixrude and Lithgow-Bertelloni, 2011), generated via a thermodynamic approach for a simplified model of mantle composition with six components: CaO, FeO, Na2O, Al2O3, MgO and SiO2 (for further details see Stixrude and Lithgow-Bertelloni, 2005, 2011).”
