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:

Yuri Amelin,William J. Davis +1 more
TL;DR: In this article, the authors measured Yb isotopic composition in 2.7 Ga zircons with Lu/YbN (chondrite-normalized) ratios of 1.40 and 1.45, respectively, in 1.0 Ga xenotime, and 0.4022124 ± 0.0000019 for the 1.4 Ma Fish Canyon Tuff (FCT) zircon and titanite as the modern reference value.

The Tatahouine diogenite: Mineralogical and chemical effects of sixty-three years of terrestrial residence
TL;DR: In this paper, a comparison between clasts of the Tatahouine diogenite, collected the day of the fall in 1931 and 63 years later in 1994, allows the evaluation of mineralogical and chemical effects of terrestrial residence on meteorites.

Differentiation of peraluminous leucogranites “en route” to the surface
Romain Tartèse,Philippe Boulvais +1 more
TL;DR: The Lizio and Questembert massifs are derived from a similar metasedimentary source (eNd(T) between −4 and −6) and have similar magmatic volumes as mentioned in this paper.

Nd and Sr isotope chronostratigraphy of Colorado Plateau lithosphere: implications for magmatic and tectonic underplating of the continental crust
TL;DR: In this article, the authors measured Nd-Sr isotopes and major and trace element abundances in lower and upper crustal xenoliths carried in Tertiary minettes and kimberlitic diatremes of the Colorado Plateau.

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.
