What Hf isotopes in zircon tell us about crust–mantle evolution
Abstract The 176 Lu–176 Hf radioactive decay system has been widely used to study
planetary crust–mantle differentiation. Of considerable utility in this regard is zircon, a …

Near-equilibrium isotope fractionation during planetesimal evaporation
Silicon and Mg in differentiated rocky bodies exhibit heavy isotope enrichments that have
been attributed to evaporation of partially or entirely molten planetesimals. We evaluate the …

Early accretion of water in the inner solar system from a carbonaceous chondrite–like source
Determining the origin of water and the timing of its accretion within the inner solar system is
important for understanding the dynamics of planet formation. The timing of water accretion …
