GENETICS, AGES, AND CHEMICAL COMPOSITIONS OF IRON METEORITES
Comparison of genetic isotopic compositions of iron meteorites with metal-silicate segregation ages suggests that the isotopic composition of the NC reservoir changed with time. By contrast, no such age-linked changes in the genetic isotopic compositions of iron meteorites from the CC reservoir are …
