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:

Geologic, Geochemical, and Geochronological Constraints on the Genesis of Gold Mineralization at Poplar Mountain, Western New Brunswick, Canada
TL;DR: The Poplar Mountain gold occurrence in western New Brunswick is hosted in the Poplar mountain volcanic complex (PMVC), which is located along the southern segment of the regional Woodstock fault zone as discussed by the authors.

The Lundy granite: a geochemical and petrogenetic comparison with Hercynian and Tertiary granites
TL;DR: In this paper, the authors show that the two main granite types (G1 and G2) cannot be discriminated, but that microgranite sheets/dykes (G3) are significantly different and more evolved, largely as a result of biotite, accessory mineral, and plagioclase fractionation.
Journal ArticleDOI
Geochemistry and Petrogenesis of Late Ediacaran Rare-metal Albite Granites of the Arabian-Nubian Shield
TL;DR: The Abu Dabbab albite granite (ADAG) as discussed by the authors is an isolated stock-like granitic body with sharp intrusive contacts against metamorphic country rocks, probably emplaced at about 600 Ma.

The emplacement, geochemistry and petrogenesis of two central Morocco Hercynian granites. Geotectonic implications
TL;DR: In this article, the emplacement and petrogenesis of two calc-alkaline Moroccan Hercynian granites: the Zaer pluton and the Djebel Aouam stocks are discussed.

Trace-element and isotope constraints on the origin of ultramafic lamprophyres from Los Alisos (Sierra Subandinas, northern Argentina)
Mario Barbieri,M.Rasaria Ghiara,Damiano Stanzione,Luisa María Villar,Norma E. Pezzutti,Susana J. Segal +5 more
TL;DR: Petrologic and geochemical analyses of an ultrabasic intrusive rock that outcrops as a 10 Km long vertical sheet near Los Alisos (Sierras Subandinas, northern Argentina), are consistent with the classification of this body as an alnoite as mentioned 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.
