  • The ratio of the refractory lithophile elements niobium and tantalum in the silicate Earth is anomalously low. Partitioning experiments suggest that the ratio of these elements is controlled by oxygen fugacity, and thus can be used to constrain the redox conditions of planetary accretion and core formation.

Here, the authors show that differences between Earth and EC are due to impact erosion of >15% of the early Earth’s mass.
