Xenoliths and other mantle-derived rocks show that the upper mantle is dominated by peridotite and Al-bearing phases that varies in compositional characteristics with increasing depth. The solar Mg/Si ratio is closely resemble to the chondritic values. The magnesium-to-silicon elemental ratio of the mantle-derived rocks is not only higher than solar, but they are thought to have a similar bulk Mg/Si ratios to that of the Solar System inner rocky planets depending on their formation location in the Solar nebula and their post-accretion processes.
