Core-mantle partitioning and the bulk Earth abundances of hydrogen and carbon: Implications for their origins
Yutaro Tsutsumi, Naoya Sakamoto, Kei Hirose +4
We determined the metal/silicate partition coefficients of hydrogen and carbon, DH and DC, simultaneously under typical conditions of Earth's core formation. Experiments demonstrat…
