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:

Caractérisation par analyse élémentaire (PIXE et ICP-MS/-AES) d'un verre naturel : l'obsidienne. Application à l'étude de provenance d'objets archéologiques
TL;DR: In this paper, the authors propose a double caracterisation -composition chimique/datation par traces de fission- for the Cappadoce, a source of the obsidienne.

Silurian turbidite provenance and the closure of Iapetus
TL;DR: In this paper, the authors present petrological and chemical data which support a coeval arc origin for detritus in the Lettergesh Formation (Silurian), western Ireland.

Chemical identification of portland cements in New Zealand concretes: I. Characteristics differences among New Zealand cements in minor and trace element chemistry
R. L. Goguel,D. A. Saint John +1 more
TL;DR: A minor and trace element survey of New Zealand cements, which included all the rare earth elements, using ICPMS, ICP-AE, AA, and AE spectroscopy showed that chemical fingerprints for all sources can be defined.

3.65–2.10 Ga history of crust formation from zircon geochronology and isotope geochemistry of the Quijingue and Euclides plutons, Serrinha nucleus, Brazil
Débora Correia Rios,Donald W. Davis,Herbet Conceição,Maria de Lourdes da Silva Rosa,William J. Davis,Alan P. Dickin,Moacyr Moura Marinho,Robert J. Stern +7 more
TL;DR: The Serrinha nucleus is one of the Archaean granite-gneiss terrains of the Sao Francisco craton, Brazil as discussed by the authors, which contains granitic rocks formed during the Trans-Amazonian orogeny, and intruded during and following a greenschist metamorphic event.

Trace element analysis of Geological Survey of Japan silicate reference materials: Comparison of SSMS with ICP-MS data and a critical discussion of compiled values
K. P. Jochum,George A. Jenner +1 more
TL;DR: The concentrations of 29 trace elements have precisely been determined in 15 international silicate reference materials of the Geological Survey of Japan by spark source mass spectrometry (SSMS) and inductively coupled plasma-mass spectrometers (ICP-MS) as discussed by the authors.

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.
