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:

Evolution of Mg/Fe Ratios in Late Variscan Plutonic Rocks from the External Crystalline Massifs of the Alps (France, Italy, Switzerland)
Debon François,Marie Lemmet +1 more
TL;DR: In this article, a comprehensive review is presented of ultramafic rocks, which display in most areas a polymetamorphic presented of all the External Crystalline Massifs and their history and underwent a highly complex pre-Variscan Late Variscan intrusions.

Isotopic and REE characteristics of the intrusive charnoenderbite and enderbite geographically associated with the Matok Pluton, Limpopo Belt, southern Africa
TL;DR: In the Limpopo Orogeny, the authors of as discussed by the authors found that the charnoenderbite and enderbite were derived from a crustal precursor and the granodiorite and granite of the Matok Pluton were intruded at approximately the same time, between ∼ 2667 Ma and ∼ 2664 Ma ago.

Bulk chemistry of Saharan shergottite Dar al Gani 476
TL;DR: In this paper, major and trace element analyses obtained by inductively coupled plasma-atomic emission spectrometry (ICP-AES) and inductively coupling plasma-mass spectrometers (ICP-MS) of three different aliquots of the new Saharan shergottite Dar al Gani (DaG) 476 were presented.

Response of zircon U−Pb isotopes and whole-rock geochemistry to CO2 fluid-induced granulite-facies metamorphism, Kabbaldurga, Karnataka, South India
C. R. L. Friend,Allen P. Nutman +1 more
TL;DR: In this article, the effect of this type of prograde transition on zircon U−Pb isotopic systematics and whole-rock geochemistry has been studied using ∼1 kg amphibolite-facies, transitional and granulite facies domains from a single block of gneiss.

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.
