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:

Quantitative analysis of original and powdered rocks and mineral inclusions by laser ablation inductively coupled plasma mass spectrometry
TL;DR: In this paper, a direct analysis of rocks by laser ablation inductively coupled plasma mass spectrometry is described, both powdered standard rocks and the original rocks were analysed and the results agreed with each other in spite of the difference in the surface states.

Mantle and crustal sources in the genesis of late-hercynian granitoids (NW Portugal) : geochemical and Sr-Nd isotopic constraints
TL;DR: In this article, a large volume of granitoids were emplaced in the Hercynian Central Iberian Zone during the last ductile deformation phase (D3, 300-320 Ma) and the biotite-rich granitoid are associated with coeval gabbro-norite to granodiorite bodies and/or mafic microgranular enclaves.

New SW Pacific tectonic model: Cyclical intraoceanic magmatic arc construction and near‐coeval emplacement along the Australia‐Pacific margin in the Cenozoic
TL;DR: In this paper, a new model is presented whereby the Papuan Ultramafic Belt (PUB) ophiolites formed and were emplaced in a cyclical fashion above an extensive NE dipping Cenozoic intraoceanic arc system which diachronously propagated (N-S) along the entire eastern margin of the Australian Plate.

The relationship between adakitic, calc-alkaline volcanic rocks and TTGs: implications for the tectonic setting of the Karelian greenstone belts, Baltic Shield
TL;DR: In this article, two types of coeval acid-intermediate rocks with different petrological, geochemical and isotopic features have been discovered among volcanic rocks and surrounding synkinematic tonalite-trondhjemite-granodiorite (TTG) plutons of Late Archaean greenstone belts in the Karelian granite-greenstone terrane.

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.
