The temperatures of shock-compressed FeS and FeS_2 in the pressure ranges 125–170 GPa and 100–244 GPa, respectively, are reported and used to constrain the melting curves and thermodynamic properties to core pressures. A fit of the Lindemann law parameters corresponding to the usual functional form for the lattice Grüneisen parameter gives γ_L = 1.17 ± 0.13 and n_L = 0.5 ± 0.5 for the high-pressure phase of FeS at ρ = 5340 kg/m^3 and γ_L = 2.18 ± 0.32 and n_L = 1.6 ± 0.7 for FeS_2 at ρ = 5011 kg/m^3. The entropies of fusion are ∼203 J kg−1 K−1 for FeS at 120 GPa and ∼180 J kg^−1 K^−1 for FeS_2 at 220 GPa. We find that the melting temperature of FeS is 3240±200 K, 4210 ± 700 K, and 4310 ± 750 K at 136 GPa, 330 GPa, and 360 GPa, respectively....
