Abstract

The metal phases of iron meteorites contain excess ^(107) Ag most plausibly derived from the in situ decay of ^(107)Pd (T_(1/2) = 6.5 x 10^6y) (Kaiser and Wasserburg, 1983; Chen and Wasserburg, 1983). The Ag isotopic data suggest that diverse types of iron meteorites, including the Type IIIABs, usually associated with fractional crystallization and core formation in planetesimals, formed and cooled to - 600°C within - 10^7y of ^(107)Pd production.
