Investigation of Antarctic Micrometeorites and Selected Carbonaceous Chondrites by Raman Spectroscopy, Electron Microscopy and Mass Spectrometry

Résumé

Concordia Antarctic micrometeorites (MMs) are micrometer-sized particles collected in Antarctic snow that are likely originating from asteroids and comets [1,2]. These samples, coming from primitive bodies (i.e. that have suffered low secondary processes), may have preserved information of the early stages of the Solar system. We analyzed three MMs from the Concordia collection (DC06-07-54, DC06-07-162 and DC06-09-249) and com- pare their mineralogical and elemental composition as well as the nature of their organic material with five selected carbonaceous chondrites with the goal of classifying them among meteorites families.
