Rare-earth abundances in chondritic meteorites
TLDR
In this article, 15 chondrites, including eight carbonaceous chondites, were analyzed for rare earth element abundances by isotope dilution, and the persistence of anomalies in chondritic materials relatively removed from direct condensational processes implies that anomalous components were introduced at a late stage of chondrite formation.About:

Synthesis of the Elements in Stars
TL;DR: In this article, a count of the stable and radioactive elements and isotopes is given, and Table I,1 shows that only promethium has not been found in nature, whereas 99 elements are found terrestrially and technetium is found in stars.

Determination of REE, Ba, Fe, Mg, Na and K in carbonaceous and ordinary chondrites
TL;DR: In this paper, the exact determination of REE and Ba abundances in three carbonaceous (Orgueil Cl, Murchison C2 and Allende C3) and seven olivine-bronzite chondrites were carried out by mass spectrometric isotope dilution technique.

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.
