The role of Bells in the continuous accretion between the CM and CR chondrite reservoirs
Meteoritics and Planetary Science, 2020 CM meteorites are dominant members of carbonaceous chondrites (CCs), which evidently accreted in a region separated from the terrestrial planets. These chondrites are key in determining the accretion regions of solar system materials, since in Mg and Cr ...

High Abundances of Presolar Grains and 15N-rich Organic Matter in CO3.0 Chondrite Dominion Range 08006. [PDF]
Geochimica et Cosmochimica Acta, 2018 NanoSIMS C-, N-, and O-isotopic mapping of matrix in CO3.0 chondrite Dominion Range (DOM) 08006 revealed it to have in its matrix the highest abundance of presolar O-rich grains (257 +76/-96 ppm, 2σ) of any meteorite.

Origin of Isotopic Diversity among Carbonaceous Chondrites
The Astrophysical Journal Letters, 2023 Carbonaceous chondrites are some of the most primitive meteorites and derive from planetesimals that formed a few million years after the beginning of the solar system.

Properties of chondrules in EL3 chondrites, comparison with EH3 chondrites, and the implications for the formation of enstatite chondrites [PDF]
Meteoritics & Planetary Science, 2002 Abstract— The study of chondrules provides information about processes occurring in the early solar system. In order to ascertain to what extent these processes played a role in determining the properties of the enstatite chondrites, the physical and chemical properties of chondrules from three EL3 chondrites and three EH3 chondrites have been examined

Rare earth elements in Proterozoic metabasalts and associated volcanogenic sulphide ore from Haveri, southwestern Finland [PDF]
Bulletin of the Geological Society of Finland, 1981 REE data on two tholeiitic metabasalts and a metalava breccia from the Haveri formation display a coherent distribution pattern from La 28 to Lu 7 times that of chondrite.

Extended chronologies of aqueous alteration in the CM2 carbonaceous chondrites: evidence from carbonates in Queen Alexandra Range 93005 [PDF]
, 2012 The Antarctic CM2 carbonaceous chondrite QUE 93005 contains four compositionally distinct carbonates, namely breunnerite, calcite, dolomite and a Ca-poor dolomite. These carbonates can form monomineralic grains, or may be intergrown as bimineralic grains

Kivesvaara C2 chondrite: silicate petrography and chemical composition [PDF]
Bulletin of the Geological Society of Finland, 1983 Fragments of the Kivesvaara meteorite were said to have been found in Paltamo, northern Finland in 1968. The chemical and mineral composition and the textural features show that this meteorite is a rare C2 carbonaceous chondrite.
