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.

Are the remains of Theia, the impactor that created the Moon, buried deep within the Earth?

The continental sized provinces at the base of the mantle were recently proposed to the remnants of Theia, the protoplanet that struck the Earth to form the Moon 4.5 billion years ago. But are other explanations for these provinces possible? See the discussion in Science.
