Correlated analyses of D- and 15N-rich carbon grains from CR2 chondrite EET 92042 [PDF]

, 2006
Extract from introduction: Insoluble organic matter (IOM) and matrix from primitive carbonaceous chondrites carry isotope enrichments (?D?20000', ?15N?3200�) that are comparable to those in interplanetary dust particles [1, this work]. Hence, primitive

Large Carbonaceous Chondrite Parent Bodies Favored by Abundance–Volatility Modeling: A Possible Chemical Signature of Pebble Accretion

The Planetary Science Journal
Primitive meteorite groups such as the Vigarano, Mighei, and Karoonda carbonaceous chondrites have enigmatic patterns of elemental abundances, with moderately volatile elements—those that transition from vapor to condensate between ∼400 and ∼900 K ...

Pułtusk H5 Chondrite—A Compilation of Chemical, Physical, and Thermophysical Data

Geosciences
The Pułtusk meteorite, classified as an H5 ordinary chondrite, is one of the best documented Polish falls, yet some important data on its physical and thermophysical properties remain limited.

Evaluating the Effects of Thermal Processing on Nucleosynthetic Zinc Isotope Variations: Insights from Carbonaceous Chondrites Leachates

The Astrophysical Journal
Variations in the nucleosynthetic isotope compositions of meteorites have been suggested to result from variable destruction of some presolar grains through thermal processing.
