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:

A metamorphic mineral source for tungsten in the turbidite-hosted orogenic gold deposits of the Otago Schist, New Zealand
TL;DR: In this article, the authors combine laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) traverses and images to show that detrital rutile is the most important host mineral for W in the subgreenschist facies rocks.

Derivation of a heterogeneous lithic fragment in the Bovedy L-group chondrite from impact-melted porphyritic chondrules
TL;DR: In this paper, petrographic, compositional and dating analyses of a light-colored lithic fragment in the L-group Bovedy meteorite that has a composition different from that of the host chondrite are presented.

Late Neoproterozoic volcano-sedimentary successions of Wadi Rufaiyil, southern Sinai, Egypt: A case of transition from late- to post-collisional magmatism
Mokhles K. Azer,E.S. Farahat +1 more
TL;DR: The Wadi Rufaiyil volcano-sedimentary successions are exposed in southern Sinai (Egypt), at the northernmost segment of the Arabian-Nubian Shield (ANS) as discussed by the authors.

Petrogenesis of the Canindé de São Francisco complex: A major Late Proterozoic gabbroic body in the Sergipe Foldbelt, northeastern Brazil
Elson P. Oliveira,John Tarney +1 more
TL;DR: In this paper, the Caninde de Sao Francisco gabbroic complex and the associated Gentileza and Novo Gosto volcanics have been analyzed and compared with the island-arc sequences.

Geochemistry of the Chagai-Raskoh arc, Pakistan: Complex arc dynamics spanning the Cretaceous to the Quaternary
TL;DR: In this article, the authors suggest that the initial phases of volcanism in the Chagai-Raskoh arc are entirely formed in an oceanic arc and that the generation of these lavas may mark the increasing proximity of the Afghan continental block.

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.
