| Résumé : | Carbonaceous chondrites, a sub-class of meteorites contain organic matter. This organic matter is a very complex mixture of various kinds of organic molecules together with a highly unsaturated polymer called kerogen. The origins of this organic matter remain a subject of active research. In the work described here, we focused our attention on volatile hydrocarbons. Ratios of heavy to light stable isotopes of carbon and hydrogen are known for this class of molecules. Comparisons between these values and the corresponding values obtained for samples resulting from Fischer-Tropsch-Type synthesis provide information about the origin of volatile hydrocarbons. The presolar origin is certainly a plausible scenario but the FTT synthesis remains a possibility. © 1993 IUPAC |
