Variations of Stable Isotope Ratios in Nature

  • Jochen Hoefs


Isotope variations found in extraterrestrial materials have been classified according to different processes — such as chemical mass fractionation, nuclear reactions, nucleosynthesis — and/or to different sources — such as interplanetary dust, solar materials, and comet material. Various geochemical fingerprints point to the reservoir from which the planetary sample was derived and the environment in which the sample has formed. They can be attributed to a variety of processes, ranging from heterogeneities in the early solar nebula to the evolution of a planetary body. For more details, the reader is referred to reviews of Thiemens (1988), Clayton (1993), and McKeegan and Leshin (2001).
