Chemical and Isotopic Diversity of Organic Particles in Chondrites : Parent Body Vs . Nebular Processes


Introduction: Insoluble organic matter (IOM), the main organic constituent in chondrites, has been extensively studied after HF/HCl isolation techniques. Bulk isotopic compositions and elemental ratios show variations between chondrite groups, whereas they are quite homogeneous within each class [1]. Recent isotopic measurements by ion probes have revealed… (More)
