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 of the Archean leucogranodiorite–granite suites: Evidence from the Rio Maria terrane and implications for granite magmatism in the Archean
José de Arimatéia Costa Almeida,Roberto Dall'Agnol,Samantha Barriga Dias,Fernando Jacques Althoff,Fernando Jacques Althoff +4 more
TL;DR: In this paper, the leucogranodiorite-granite (LGdG) suites are represented by the 2.87-Ga Guaranta suite which includes the Trairao and Azulona granodiorites and the Guaranta granite plutons.

Lower Brioverian formations (Upper Proterozoic) of the Armorican Massif (France): geodynamic evolution of source areas revealed by sandstone petrography and geochemistry
TL;DR: In this article, the formation with interbedded cherts is interpreted as having been deposited during an early stage of magmatic arc activity (around 640-630 Ma ago) in an immature marginal basin.

Tectonic record, magmatic history and hydrothermal alteration in the Hercynian Guérande leucogranite, Armorican Massif, France
Christophe Ballouard,Philippe Boulvais,Marc Poujol,Denis Gapais,Philippe Yamato,Romain Tartèse,Michel Cuney +6 more
TL;DR: The Guerande peraluminous leucogranite was emplaced at the end of the Carboniferous in the southern part of the Armorican Massif as discussed by the authors, and its country rocks demonstrate both E-W and N-S stretching.

Characterization and correlation of Upper Jurassic (Oxfordian) bentonite deposits in the Paris Basin and the Subalpine Basin, France
Pierre Pellenard,Jean-François Deconinck,Warren D. Huff,Jacques Thierry,Didier Marchand,Dominique Fortwengler,Alain Trouiller +6 more
TL;DR: Explosive volcanic activity is recorded in the Upper Jurassic of the Paris Basin and the Subalpine Basin of France by the identification of five bentonite horizons as discussed by the authors, which indicate that significant explosive volcanic events occurred during the Middle Oxfordian and provide potential long-distance isochronous marker beds.

Evolution of the Ligurian Tethys in the Western Alps: Sm/Nd and U/Pb geochronology and rare-earth element geochemistry of the Montgenèvre ophiolite (France)
Sylvie M Costa,Renaud Caby +1 more
TL;DR: In this article, geochemical and geochronological data for gabbro, diorite and albitite samples from the Montgenevre ophiolite in the Western Alps were provided.

Advanced Inorganic Chemistry
TL;DR: Cotton and Wilkinson's Advanced Inorganic Chemistry (AIC) as discussed by the authors is one of the most widely used inorganic chemistry books and has been used for more than a quarter century.

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.
