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:

ORIGIN AND DISTRIBUTION OF SOME TRACE ELEMENTS IN METAMORPHOSED Fe–Mn DEPOSITS, VAL FERRERA, EASTERN SWISS ALPS
Joël Brugger,Reto Gieré +1 more
TL;DR: In this article, the authors investigated the role of the hydrothermal fluid within the granite-bearing basement underlying the sedimentary rocks and inferred the most likely mechanism for the derivation of the Be and W concentrated in the ores.

Importance of melt fraction and source rock composition in crustal genesis — the example of two granitic suites of northern Portugal
TL;DR: In this paper, two varieties of syn- to late-tectonic Hercynian aluminous granitoids are distinguished: (1) muscovite-rich, two-mica granites, forming many successively emplaced bodies with little chemical variation.

The marine geochemistry of the rare earth elements
TL;DR: In this article, the gamma spectra of rare earth elements (REE) in seawater were used for the determination of 12 of the 14 most commonly used elements in the literature, including Pr, Tb, Ho, Tm and Lu.

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.
