Cosmic-ray production of tungsten isotopes in lunar samples and meteorites and its implications for Hf-W cosmochemistry
Excesses and deficiencies in 182W in meteorites and lunar samples relative to the terrestrial 182W atomic abundance have been assigned to the decay of 182Hf (t(1/2)=9 Ma) and have been used to date metal-silicate fractionation events in the early solar system. Because the effects are very small, pro...
