Carbon, Nitrogen, and Silicon Isotopic Ratios in Kjg Presolar Sic Grains from Murchison


Introduction: SiC is the best-studied type of presolar grains [1]. Thousands of individual grains have been measured for their C and Si isotopic compositions [2-4] and many of these have been measured for additional isotopic systems, as well. Despite this wealth of data and the fact that Ti is one of the most abundant trace elements in SiC, only… (More)
