“From seismic wave reflections on the boundary between the core and mantle of Mars, the team was able to determine that Mars has a large core. A large core implies a mantle mineralogically similar to the terrestrial upper mantle and transition zone but differing from Earth by not having a bridgmanite-dominated lower mantle. However, Mars differs from Earth in its core. The Martian core is much less dense, implying that a number of light elements such as oxygen and sulfur are dissolved in the iron and nickel core. This observation is hardly compatible with classical models of planet formation.”
