Micrometeorites from Central Antarctica (CONCORDIA Collection): Noble Gases - Indication for a Single Population?

We present our first noble gas results (He, Ne, Ar, Kr and Xe) for 2 crystalline and 3 fine-grained micrometeorites (MMs)from Central Antarctica (CONCORDIA collection). The MMs display similar Ne and Xe ratios, which may indicate a single population.
