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

摘要

This report presents the primary results of experiments at 5.5 GPa and 1600A degrees 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.
