Lead isotope planetary profiling (LIPP): Summation-depiction of Earth's many reservoirs

An approach aiming at a summation-depiction of the isotopic characteristics of a planet is attempted. The approach, Lead Isotope Planetary Profiling (LIPP), is a thematic derivation from the general field of planetary geochemistry. Specifically, the recently developed methodology of Pb isotope synchronism, which often allows the accurate dating of disturbed geologic systems, has been applied to a large body of terrestrial Pb isotopic data in the literature. The exercise resulted in 26 Pb/Pb lines most of which appear to be highly precise isochrons.
