摘　　要：The paper by Liu et al.[1]is aimed to discuss the role of oldhamite(CaS)in the understanding of the C-O-S-Ca cycles of the Earth.The results of this manuscript also demonstrate the meaning of the presence of oldhamite on the surface and interior of a planet by taking a view of its stability on Earth as well as on other bodies in the Solar System.Oldhamite(Fm-3 m,a=5.69Awith V/10^(6) pm^(3)=184.88)is stable in highly reducing conditions with an oxygen fugacity below IW+3.3(IW=iron-wüstite redox buffer,in lofo2)[1].
