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:

Mesozoic felsic arc magmatism and continental olivine tholeiites in Zhejiang Province and their relationship with the tectonic activity in southeastern China
TL;DR: The Mesozoic geology of Zhejiang Province in southeastern China is characterized by two distinct geodynamic settings separated by a major tectonic event as discussed by the authors, which is likely related to the collision of the China-Indochina margin with the West Philippine Block.

TL;DR: In this article, a geochemical and geochronological analysis of zircon cores from the Aghbar trachytic sill and from the Bou Madine rhyolitic dome has been shown to be of Statherian age (ca. 1600-1800 Ma).

Archean and Paleoproterozoic crust of the São Francisco Craton, Bahia, Brazil: geodynamic features
TL;DR: In this paper, the authors identify four important crustal segments in the basement of the Sao Francisco Craton in Bahia, Brazil, which are associated with Archean greenstone belts.

Geochemistry of peridotite xenoliths in basalt from Hannuoba, Eastern China: Implications for subcontinental mantle heterogeneity
Yan Song,Frederick A. Frey +1 more
TL;DR: Based on geochemical studies of six spinel peridotite xenoliths in basanite, the upper mantle beneath Hannuoba, eastern China is compositionally heterogeneous as mentioned in this paper.

The Gabal Gerf complex: A precambrian N-MORB ophiolite in the Nubian Shield, NE Africa
TL;DR: The Cabal Gerf mafic-ultramafic complex, the largest Neoproterozoic ophiolite in the Arabian-Nubian Shield and located near the Red Sea in the border region between Egypt and the Sudan, was reported in this paper.

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.
