| Abstract: | Based on the heterogeneity in the contents and isotopic compositions of carbon, nitrogen, and rare gases found in different (in grain size) interstellar diamond fractions of the meteorite Efremovka, we discuss issues associated with the nature of the diamond, the distribution of the isotopic components of impurity chemical elements in it, and the kinetics of their release. |
