Abstract
The radiogenic nature of Pb in average crust and mantle probably requires some interaction between mantle and core during core formation and is thus incompatible with heterogeneous accretion models for the Earth. Pb isotope evolution models for hot and cool accretion indicate that core formation was not quasi-simultaneous with accretion although the core was probably 95% completed within the first 700 Myr of the Earth's history.
