Distribution of the pre-solar component in allende and other carbonaceous chondrites
TLDR
In this article, a detailed analysis of separated phases of several Allende Ca-Al-rich inclusions is reported, which reveal a consistent pattern of large O-16 enrichments in spinel, pyroxene, and sometimes olivine, and small O- 16 enrichment in melilite, feldspathoids, and grossular.About:

Oxygen isotope studies of achondrites
TL;DR: In this article, the isotopic compositions of aubrites coincide with the Earth and Moon, and also with the enstatite chondrites, and they also support the following genetic associations: (1) winonaites and IAB-IIICD irons, (2) acapulcoites and lodranites, and (3) ureilites and dark inclusions of C3 chondites.

Oxygen isotope studies of carbonaceous chondrites
TL;DR: In this paper, a comprehensive set of whole-rock analyses of CV, CO, CK, CM, CR, CH, and CI chondrites is presented, as well as selected components of some of these meteorites.

TL;DR: Petrographic analyses of CM matrices characterized four phyllosilicates in Murray and Murchison meteorites and Fe- and Mg-serpentines in Nogoya as discussed by the authors.

The use of bromine pentafluoride in the extraction of oxygen from oxides and silicates for isotopic analysis
TL;DR: In this paper, a technique was developed in which bromine pentafluoride was used as a reagent for quantitative liberation of oxygen from oxides and silicates, and the results of isotopic analyses were compared with measurements made in other laboratories by other procedures.

Condensation in the primitive solar nebula
TL;DR: In this article, the distribution of the major elements between vapor and solid has been calculated for a cooling gas of cosmic composition, assuming that high temperature condensates remain in equilibrium with the vapor, affecting the temperatures of appearance of successively less refractory phases.

A component of primitive nuclear composition in carbonaceous meteorites.
TL;DR: The oxygen of anhydrous, high-temperature minerals in carbonaceous meteorites is strongly depleted in the heavy stable isotopes 17O and 18O and probably results from the admixture of a component of almost pure 16O.

A classification of meteorites based on oxygen isotopes
TL;DR: On the basis of 18O/16O and 17O/ 16O ratios, meteorites and planets can be grouped into at least six categories, as follows: (1) the terrestrial group, consisting of the earth, moon, differentiated meteorites, and enstatite chondrites; (2) types L and LL ordinary chondrite; (3) type H ordinary chonderes; (4) anhydrous minerals of C2, C3, C4 carbonaceous chondites; (5) hydrous matrix minerals of c2 carbonaceous

Mineralogy, mineral-chemistry, and composition of the Murchison (C2) meteorite
TL;DR: Fuchs et al. as discussed by the authors identified the Murchison meteorite as a type II carbonaceous chondrite (C2) and reported that the chondrules are not texturally typical of the ordinary chondrites, but resemble more closely those chond rules seen in C3 and C4 chondites.
