Nitrogen Isotopic Imaging of Tagish Lake Carbon GlobulesChondritic meteorites and interplanetary dust particles commonly exhibit significant enrichments in deuterium (D) and N-15 relative to terrestrial materials. These anomalies are usually ascribed to low temperature chemical processes occurring in a presolar cold molecular cloud and/or physically similar regions of the outer solar nebula. The sizes of these anomalies vary considerably among different classes of meteorites, in some cases on a microscopic scale, reflecting differing degrees of alteration and dilution of the presolar components owing to parent body processing.
