We are grateful to the French and Italian polar institutes, IPEV and PNRA, for their financial and logistic support. The NanoSIMS facility was established with funding from the CNRS, Région île de France, MESR, and MNHN. The electron microscopy work in Lille is a national facility instrument INSU-CNRS. We are grateful to M. Maurette for stimulating exchanges and pioneering the micrometeorite research in Orsay; S. Derenne, E. Jacquet, E. Quirico, and G. Slodzian for enlightening discussions; and M. Horlok for careful reading of the manuscript.
