Hugoniot compression curve for the mixture of Fe/FeO/FeS (58.96%/35.83%/5.21%, mass fraction) has been measured from 50 to 210 GPa, using two-stage light-gas gun and electric pin technique. The measured Hugoniot parameters are: C0=(3.97±0.07) km/s, λ=1.58±0.03 and initial density ρ0=(6.69±0.06) g/cm3. Based on additive volume law, the compressional curves of this mixture along Hugoniot and along 0 K isothermal were also calculated respectively according to the Hugoniot curve and 0 K isothermal relevant to the ingredients, which showed both are consistent well with the experimental Hugoniot and the 0 K isothermal deduced from the experimental Hugoniot using the Wu's method. Thus it demonstrated the rationality of this experimental Hugoniot and the applicability of the additive volume law hold for this mixture. For the letter, it also implies that no detectable chemical reactions happen between Fe, FeO, FeS ingredients while they were subjected to shock compression in this work. The above mentioned results provide a basis for investigating the candidate concentrations of Earth's outer core if it is a Fe-O-S assembly, for the further details.
