AbstractWe report on the detection of primordial organic matter within the carbonaceous chondrite Maribo that is distinct from the majority of organics found in extraterrestrial samples. We have applied high-spatial resolution techniques to obtain C-N isotopic compositions, chemical, and structural information of this material. The organic matter is depleted in 15N relative to the terrestrial value at around δ15N ~ -200‰, close to compositions in the local interstellar medium. Morphological investigations by electron microscopy revealed that the material consists of µm- to sub-µm-sized diffuse particles dispersed within the meteorite matrix. Electron energy loss and synchrotron X-ray absorption near-edge structure spectroscopies show that the carbon functional chemistry is dominated by aromatic and C=O bonding environments similar to primordial organics from other carbonaceous chondrites. The nitrogen functional chemistry is characterized by C-N double and triple bonding environments distinct from what is usually found in 15N-enriched organics from aqueously altered carbonaceous chondrites. Our investigations demonstrate that Maribo represents one of the least altered CM chondrite breccias found to date and contains primordial organic matter, probably originating in the interstellar medium.

The Impact

Meteorites are extraterrestrial objects that survive the impact on the Earth's surface. A particular class of meteorites, carbonaceous chondrites, are very old, having remained nearly unaltered since the formation of the solar system approximately 4.6 billion years ago. They contain a rich organic inventory of abiotic molecules with important roles in present day biochemistry. The present article describes the organic compounds present in meteorites, their sources and how to distinguish extraterrestrial organic matter from their terrestrial counterparts.
