Oxygen Isotope Ratios of Large Cosmic Spherules: Carbonaceous and Ordinary
Introduction: Based on petrographic and ion probe investigation of small micrometeorites (150–250 μm), previous studies (e.g. [1]) have concluded that 99% of them should come from carbonaceous, possibly cometary parent bodies (CM/CR related). Our oxygen isotope measurements of 33 large (>500 μm) silicate type cosmic spherules (CS), using IR-laser fluorination/mass spectrometry, indicate that 30...
متن کاملIntermineral oxygen three-isotope systematics of silicate minerals in equilibrated ordinary chondrites.
High precision oxygen three-isotope ratios were measured for four mineral phases (olivine, low-Ca and high-Ca pyroxene, and plagioclase) in equilibrated ordinary chondrites (EOC) using a secondary ion mass spectrometer. Eleven EOCs were studied that cover all groups (H, L, LL) and petrologic types (4, 5, 6), including S1-S4 shock stages, as well as unbrecciated and brecciated meteorites. SIMS a...
متن کاملThe hydrology of carbonaceous chondrite parent bodies and the evolution of planet progenitors
Oxygen isotope ratio data from carbonaceous chondrites are explained if aqueous fluids flowed from high to low temperatures within the parent objects of these primitive meteorites. Recognition of ancient hydrological activity on primitive asteroid precursors affords a new class of constraints on the heat sources (ages?) and sizes of planet precursors in the early Solar System based on the geolo...
متن کاملOxygen Isotope Ratios in the Crust of Iron Meteorites
The separation factor, aM-0= ( 1 8 0 / 1 6 0 ) magnetite/' ( 1 8 0 / 1 6 0 ) atmospheric oxygen, between the magnetite crust of iron meteorites and atmospheric oxygen has been determined to be 0.9946 ± 0.0005. It is concluded that this fractionation of the oxygen isotopes is the consequence of an equilibrium isotope effect at high temperatures. It can be assumed that this is also valid for cosm...
متن کاملHigh precision oxygen three-isotope analyses of anhydrous chondritic interplanetary dust particles
Oxygen three-isotope ratios of three anhydrous chondritic interplanetary dust particles (IDPs) were analyzed using an ion microprobe with a 2 lm small beam. The three anhydrous IDPs show DO values ranging from )5& to +1&, which overlap with those of ferromagnesian silicate particles from comet Wild 2 and anhydrous porous IDPs. For the first time, internal oxygen isotope heterogeneity was resolv...
