TLDR
In this paper, the major constituents of chondritic matter are fractionated among the several chondrite classes in the solar nebula, starting from material of carbonaceous chondrites composition.About:

Presolar components in the ordinary chondrites
TL;DR: In this paper, the presence of presolar components in ordinary chondrites may have important implications for the degree of reprocessing their precursor materials can have experienced in the nebula.

Distribution of Ni, Ga, Ge and Ir between metal and silicate portions of H-group chondrites
TL;DR: In this article, the concentration ratios of Ni, Ga, Ge, Ge and Ir have been determined in the metal and silicate portions of 21 chondrites, including 15 H groups.

Compositions of droplet chondrules in the Manych (L-3) chondrite and the origin of chondrules
TL;DR: In this paper, expanded beam microprobe analyses of 18 drop-formed chondrules and 5 irregular masses of devitrified glass in the Manych chondrite show trends and ranges of chemical variation similar to those reported previously for large microporphyritic chond rules in this meteorite.

Thermal metamorphism of primitive meteorites—XL The enstatite meteorites: origin and evolution of a parent body
TL;DR: In this article, the authors reported trace element losses above 1000 C by diffusion-controlled processes with apparent activation energies of 8 to 55 kcal/mol; these data together with abundances of aubrites, Mt. Egerton, and E4-6 chondrites, and isotopic results link all enstatite meteorites to a common parent body.

Are C1 chondrites chemically fractionated? a trace element study
TL;DR: In this paper, the results of consistency checks on a number of elements are discussed, including rare earths and other refractories, compositional uniformity of C1's, and interelement correlations.

A chemical-petrologic classification for the chondritic meteorites.
W. R. Van Schmus,John A. Wood +1 more
TL;DR: In this article, a two-dimensional classification grid based on chemical and petrologic subdivisions of chondritic meteorites is proposed, which extends the current chemical subdivisions to account for varying petrolic (implied metamorphic) properties within the primary chemical groups.
