The chemical composition of the Earth: Enstatite chondrite models
We propose a new model of Earth's bulk composition based on enstatite chondrites (E-
chondrites), the only chondrite group isotopically identical to the Earth. This model allows a …

The nature of Earth's building blocks as revealed by calcium isotopes
Calcium is the fifth most abundant element in the Earth and in chondrites and is a pure
lithophile element which does not partition into planetary cores. Therefore, the calcium …
