QUOTE {}The Earth therefore formed exclusively from inner Solar System material whose composition did not vary over the course of accretion and was, on average, unlike that of any chondrite.
QUOTE {}The isotopic compositions of ε100Ru and ε48Ca ... constrain fCI to below 0.3 ± 0.1% or <0.1−0.03+0.05%, respectively ... ε48Ca constrains fCI to below 2 ± 0.2% in the BSE and, as a refractory lithophile element, in the bulk Earth.
