Can galactic chemical evolution explain the oxygen isotopic variations in the solar system?
A number of objects in primitive meteorites have oxygen isotopic compositions that place them on a distinct, mass-independent fractionation line with a slope of one on a three-isotope plot. The most popular model for describing how this fractionation arose assumes that CO self-shielding produced16O-rich CO and16O-poor H2O, where the H2O subsequently combined with interstellar dust to form relatively16O-poor solids within the solar nebula. Another model for creating the different reservoirs...[Show more]
