  ERC - High precision isotopic measurements of heavy elements in extra-terrestrial materials: origin and age of the solar system volatile element depletion

PRISTINE

The objectives of this proposal, PRISTINE, are to develop new cutting edge high precision isotopic measurements to understand the origin of the Earth, Moon and solar system volatile elements and link their relative depletion in the different planets to their formation mechanism.

In addition, the understanding of the origin of the volatile elements will have direct consequences for the understanding of the origin of the Earth’s water. The stable isotope composition will give us new constraints on the mechanisms that have shaped the abundances of the volatile elements in terrestrial planets, while the timing will be used to differentiate between nebular events (early) from planetary events (late).

These new results will have major implications on our understanding of the origin of the Earth and of the Moon, and they will be used to test the giant impact hypothesis of the Moon and the origin of the Earth’s water.
