Investigation of Ultracarbonaceous Antarctic Micrometeorites by Analytical Transmission Electron Microscopy

International audience Ultracarbonaceous micrometeorites were studied by TEM in order to understand the mineralogy and petrology of probable cometary grains. GEMS, and spherical objects with an igneous signature similar to chondrules were observed in these samples.
