The composition of the core is determined by difference,without resorting to assumptions about core formation processes.It is found that the core contains about 7.3 wt% silicon and 2.3 wt% sulphur.To account for the seismologically determined density deficit of the core,about 4 wt% oxygen must be added.The present results are compatible with the idea that the core material equilibrated at low(PDF) The Chemical-Composition of the EarthSep 01,1995·Earth's core consists of 80-90% Fe-Ni alloys and 2.3wt% sulfur [24].Fe-Ni sulfides Nickel and cobalt as members of the iron group are often found together with iron and are also of Cited by 11978Publish Year 1995Author W.F.McDonough,S.-s.SunComposition of the Earth (Structure + Layers + Facts Feb 14,2017·The crust is mostly composed of silica,alumina,lime,magnesia,and iron oxide (rust).
