Correlated helium-3 and tungsten isotopes in iron meteorites: quantitative cosmogenic corrections and planetesimal formation times
Core formation in planetesimals can, in principle, be dated using the short-lived 182Hf–
182W chronometer. However, it has been predicted that burnout and production of W …
