Oxygen Isotopes in Co3 Chondrites
نویسندگان
چکیده
Introduction: The results of a number of studies seem to indicate that CO3 chondrites can be subdivided into a metamorphic series analogous to that seen in ordinary chondrites [1,2,3]. It has been suggested that this sequence is the result of hydrothermal alteration on the CO parent body [4]. One particularly intriguing feature of CO3 chondrites is the reported general correlation between whole rock oxygen isotope values and petrographic subtype, such that values appear to become increasingly O-rich with increasing metamorphic grade [4,5]. In view of the importance of trying to disentangle nebular from later parent body processes we have undertaken a further investigation of the oxygen isotope systematics of CO3 chondrites.

Introduction: Presolar grains have been identified in primitive members of all chondrite classes [1,2]. The isotopic compositions of presolar grains provide probes of galactic evolution and nucleosynthesis in stars [3,4], while the abundances and characteristics of presolar grains contain a record of thermal processing in the solar system [2,5]. Most of the detailed isotopic work has been done ...

متن کاملPhotochemical Speciation of Oxygen Isotopes in the Solar Nebula
We have performed time-dependent photochemical calculations of CO selfshielding in the surface region of a turbulent nebula, and demonstrated that substantial mass-independent fractionation in bulk oxygen isotopes in the nebula was possible on timescales of 10 years. CO photodissociation in the presence of abundant H2 yields δvalues for nebular H2O with δO/δO near 1.0, consistent with measureme...
