Lead in Martian Meteorites-- Observations and Inconsistencies: I. Chassigny [PDF]

The history of Pb isotope analyses of the martian meteorites (SNC) and their interpretations is laden with difficulties. Two different analytical groups have interpreted their ancient ( 4 Ga) shergottite Pb ages as primary [1-5].
