The bulk of meteorites consist of material that condensed out of the primitive solar nebula, and their isotopic composition is therefore similar to that of the sun. Unfractionated meteorites (carbonaceous chondrites), nevertheless, contain a small fraction of inclusions that have a distinctly different isotopie composition of carbon, xenon, krypton and other elements (Zinner et al., 1987). These inclusions are therefore believed to be of pre-solar origin, and their composition and mineralogical structure carries information about the place where they were born.
