Early Volatile Depletion and Rapid Core Formation in the Earth: Evidence from the ^5^3Mn-^5^3Cr System
Abstract
The ^5^3Mn-^5^3Cr system of Earth compared to meteorites indicates volatile depletion in Earth within the first million years. Core formation began at the same time. The Cr-isotopic composition of the core is different from the mantle.
