This study was funded at Nancy by the Centre National de la Recherche Scientifique (CNRS), the Région Lorraine, and the Centre National d'Etudes Spatiales (CNES), at Minnesota by grant NAG5-11732 from the NASA Cosmochemistry Program, and at Berkeley by NASA grant NNG05GR30G. Part of this work was performed under the auspices of the U.S. Department of Energy by Lawrence Livermore National Laboratory under contract DE-AC52-07NA27344. We thank M. C. Martin [Advanced Light Source, Lawrence Berkeley National Laboratory (ALS, LBNL)] for helpful discussions. Z. Gainsforth (UC Berkeley, Space Science Laboratory), and M. Marcus and S. Fakra (ALS, LBNL), provided crucial support for the x-ray absorption near-edge structure analyses. Suggestions from three reviewers greatly improved the presentation. Encouragement from the Stardust Preliminary Examination Team, in particular from K. McKeegan and D. E. Brownlee, is gratefully acknowledged. This is CRPG contribution 1870.
