Abstract
An important question currently vi-gorously discussed is if all nakhlites and possibly Chassigny were ejected by the same impact event from a common Martian location. However, the uncertainties of cosmic-ray exposure (CRE) ages are usually high and thus the crucial point in this discussion. Here we present CRE ages for Nakhla (Nak), Lafayette (Laf) and Chassigny (Chas) studied by 40Ar-39Ar dating of irradiated mineral separates and whole rocks. We also report CRE ages for these meteorites and Governador Valadares (GV) using the cosmogenic nuclides 3He, 21Ne, and 38Ar in unirradiated whole rock samples.
