P- and S-wave velocity measurement of lunar orthopyroxene up to 5.5 GPa and 1273 K: Implication for the iron content of the lunar upper mantle

Source data Fig.1: Experimental pressure, temperature, P- and S-wave velocities (VP and VS) and volume of orthopyroxene. Pressure, VP, VS and volume of the 300 K, 473 K, 673 K, 873 K, 1073 K and 1273 K isotherms derived from fitting experimental data by a eulerian finite strain equation of state to the 3rd order.Source data Fig.2: Fe# =Fe/(Mg+Fe), KS0, G0 and volume of orthopyroxene reported in this and previous studies.Source data Fig.3: VP, VS and density of the En84Fs13Wo3 orthopyroxene (64 vol.%) + Fo87 olivine (36 vol.%) model and En80Fs20 orthopyroxene (64 vol.%) + Fo80 olivine (36 vol.%) model along the lunar geotherm. VP, VS and density of lunar seismic models reported in previous studies.
