Deep mantle krypton reveals Earth’s early accretion of outer solar system planetesimals

Our new paper,  led by postdoctoral scholar Dr. Sandrine Péron on the krypton isotopic composition of mantle plumes is out. The research provides evidence for very early accretion of carbonaceous materials by Earth along with a nucleosynthetic anomaly in a neutron-rich krypton isotope.  You can read a short synopsis here.
