Eutectic melting in the system Fe–S to 44 GPa

2007-5-15 · Thus, if sulfur is the main light component in the Earth''s core, the sulfur content would have to be below 10 wt.%, because the density contrast between the inner and outer cores implies that the core composition is on the iron-rich side of the eutectic. At 44 GPa, we find eutectic melting temperatures that are about 1000 K below that of pure iron.
