Stable Isotopic Compositions of Hydrogen, Carbon, Nitrogen, Oxygen and Sulfur in Meteoritic Low Temperature Condensates

摘要: The study of light element stable isotopes (D/H, 13C/12C, 15N/14N, 18O/17O/16O/ 36S/34S/33S/32S) in meteorites gives an insight into processes which occurred during, and indeed before, the formation solar system. more refractory element-containing components preserve isotopic signatures recorded pre-solar events or imparted high temperature regions nebula. characteristics low condensates (organic matter etc.) are result cooler origin these materials is obviously relevant to other system bodies such as outer planets comets.
