a chondritic IDP

ABSTRACT
Interplanetary dust particles (IDPs) and primitive
meteorites exhibit enrichments of deuterium and 15N, but the
carrier phases of these anomalies are poorly characterized.
Furthermore, it is not clear if the carriers are the same in
both types of materials. We have used the new NanoSIMS at
Washington University to compare the microdistributions of C
and N isotopic compositions in various IDPs and fragments of
Renazzo matrix material.
