Zinc isotope anomalies in primitive meteorites identify the outer solar system as an important source of Earth's volatile inventory by Savage, Paul S., Moynier, Frédéric, Boyet, Maud

“…The source of and timing of delivery of the volatile elements to Earth is a question that is fundamental to understanding how our planet evolved. Here, we show…”
