Scientific paper

Experimental studies and model calculations have demonstrated that liquid iron can react chemically with silicates at pressures prevailing at the Earth's core-mantle boundary (140 GPa). The reactions are believed to be responsible for the development of chemical heterogeneites at the core-mantle boundary and for the incorporation of light elements into the Earth's core. It has also been suggested that similar reactions may occur during the early accretion history of the Earth. In this work we studied metal-silicate relations in two samples of the Saratov (L4 fall) chondrite loaded by a converging shock wave up to a pressure and a temperature prevailing in the Earth's inner core. The experiments show a progressive oxidation of Fe,Ni metal with increasing pressure. Above a certain pressure only a Fe-rich silicate melt and metal-sulfide liquids coexist. Such sulfide liquids probably govern the distribution of siderophile elements in the core-mantle system.
