The Bencubbin chondrite breccia and its relationship to CR chondrites and the ALH85085 chondrite

Meteoritics, 1990
Abstract— Bencubbin is an unclassified meteorite breccia which consists mainly of host silicate (∼40 vol.%) and host metal (∼60%) components. Rare (< 1%) ordinary chondrite clasts and a dark xenolith (formerly called a carbonaceous chondrite clast) are also found.

Oxygen isotopes in R-chondrite magnetite and olivine: links between R chondrites and ordinary chondrites

Geochimica et Cosmochimica Acta, 2000
Ion-microprobe studies yield Δ17O (=δ17O − 0.52 · δ18O) values in magnetite from the Rumurti chondrite (RC) PCA91241 (which is paired with PCA91002) of +3.1 to +3.9‰, slightly higher than that in O from whole-rock R samples. Despite Δ17O values in whole-rock RCs that are much (by ca.

Feldspar in Chondrites

Science, 1965
Whereas most chondrites contain sodic plagioclase (or occasionally maskelynite, its glassy equivalent), a few are free of feldspar. Absence of plagioclase is correlated with the presence of calcium-poor clinopyroxene (pigeonite sensu lato ) instead of orthopyroxene.

Chainpur-like Chondrites: Primitive Precursors of Ordinary Chondrites?

Science, 1966
Chainpur and similar, apparently primitive, chondritic meteorites may be precursors of ordinary chondrites; a variety of evidence supports this working hypothesis. In general, carbonaceous chondrites seem to be related collaterally to this genetic sequence rather than being direct ancestors of ordinary chondrites.
