Abstract

Organic matter in extraterrestrial materials has isotopic anomalies in hydrogen and nitrogen that suggest an origin in the presolar molecular cloud or perhaps in the protoplanetary disk. Interplanetary dust particles are generally regarded as the most primitive solar system matter available, in part because until recently they exhibited the most extreme isotope anomalies. However, we show that hydrogen and nitrogen isotopic compositions in carbonaceous chondrite organic matter reach and even exceed those found in interplanetary dust particles. Hence, both meteorites (originating from the asteroid belt) and interplanetary dust particles (possibly from comets) preserve primitive organics that were a component of the original building blocks of the solar system.

  19. Large 15 N enrichments (up to δ 15 N ∼2500‰) have been found in CB and CH chondrites [e.g. ( 29 )]. However the origin of these anomalies is unknown and their carriers may be secondary phases.

  23. One 5-μm 2 region in EET 92042 IOM is isotopically anomalous in both N and C (δ 15 N = 1150 ± 40‰ δ 13 C = –113 ± 14‰) a composition closely similar to a putative interstellar C grain reported in an IDP ( 9 ). All other observed C anomalies originate from presolar SiC grains ( 15 ) embedded in the samples.
