Migration of molten iron through an olivine matrix in the presence of carbon at high P–T parameters (experimental data)

This report presents the primary results of experiments at 5.5 GPa and 1600°C on the migration of molten iron through a solid silicate matrix consisting of olivine crystals with graphite-filled interstices. It was shown that the migration rate was quite high at the given P and T values (up to 2.5 mm/h). It was shown that carbon in its elemental forms might affect the migration capability of molten iron. This effect must be included in creating a correct model of the formation of the inner parts of the Earth, the terrestrial planets, and planetoids.
