supporting infomation for "High-pressure and high-temperature single-crystal elasticity of Cr-pyrope: implications for the density and seismic velocity of subcontinental lithospheric mantle"

This is the supplementary file for the article "High-pressure and high-temperature single-crystal elasticity of Cr-pyrope: implications for the density and seismic velocity of subcontinental lithospheric mantle". it includes 2 supplementary text, 5 figures, and 6 Tables.

Supplementary text 1 and text 2 describe the used thermal-pressure equation of state and finite-strain equations, respectively.

Figures S1-S3 show the calculated phase diagrams, minerals proportions, and Cr-pyrope end-member proportions of different SCLMs, respectively. Figure S4 shows the density ρ, bulk modulus KS and shear modulus G of Prp-Cr#12 along isotherms at 1000 K and 1600 K over 3-8 GPa. Figure S5 shows the calculated mineral proportions of three SCLMs, Archon, Proton, and Tecton at 3-8 GPa along isotherms at 1300 K and 1500 K.

Table S1 describes the average compositions of the Archon, Proton, and Tecton SCLM adopted from Griffin et al. (2009). Table S2 shows the mineral proportions and compositions of the Archon, Proton and Tecton as a function of pressure and temperature. Table S3 shows the chemical composition of the Cr-pyrope in this study. Table S4 shows the elastic properties of Cr-pyrope and end-member pyrope. Table S5 shows the elastic parameters of minerals used for density and velocity calculations. Table S6 shows the mineral proportions and compositions of the Archon, Proton and Tecton as a function of pressure and temperature.
