Stable-isotopic anomalies and the accretionary assemblage of the Earth and Mars: A subordinate role for carbonaceous chondrites
PH Warren - Earth and Planetary Science Letters, 2011 - Elsevier
Plots such as ε54Cr vs. ε50Ti and ε54Cr vs. Δ17O reveal a fundamental dichotomy among
planetary materials. The “carbonaceous” chondrites, by virtue of high ε50Ti and high ε62Ni …
