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:

U–Pb zircon dating of post-obduction volcanic-arc granitoids and a granulite-facies xenolith from New Caledonia. Inference on Southwest Pacific geodynamic models
TL;DR: In New Caledonia, the occurrence of one of the World's largest and best-exposed subduction/obduction complex is a key point for the understanding of the geodynamic evolution of the whole Southwest Pacific region as mentioned in this paper.

Geochemistry and tectonic significance of the Tangihua Ophiolite Complex, New Zealand
TL;DR: The ophiolitic igneous complexes of the Tangihua Complex of Northland, New Zealand consist of massive and pillowed basaltic lava sequences with intercalated sediments and lesser gabbro, microgabbro and basaltitic intrusions as discussed by the authors.

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.
