The group separation of the rare-earth elements and yttrium from geologic materials by cation-exchange chromatography
TLDR
In this article, two separate gradient strong-acid cation exchange chromatography procedures were characterized and the major elements as well as those elements thought to provide the greatest interference for the determination of the rare-earth elements (REE) and yttrium in geologic materials were tested for separation from the REE.About:

Rare earth elements in river waters
TL;DR: In this article, the authors measured the input to the oceans of rare earth elements (REE) in the dissolved and the suspended loads of rivers, and found that the dissolved loads in the five major rivers had relatively heavy-REE enrichments relative to the NASC and the suspension material, with the (La/Yb)N ratio of about 0.4.

Origin of anomalous rare-earth element and yttrium enrichments in subaerially exposed basalts: Evidence from French Polynesia
J. Cotten,A. Le Dez,Michael Bau,Martial Caroff,René C. Maury,Peter Dulski,Serge Fourcade,Marcel Bohn,R. Brousse +8 more
TL;DR: In this article, rare-earth elements (REE) and yttrium (Y) were enriched in French Polynesian basaltic sequences, indicating a close relationship to supergene processes.

Rare earth, major, and trace elements in chert from the Franciscan Complex and Monterey Group, California: Assessing REE sources to fine-grained marine sediments
TL;DR: This article showed that the relative importance of metalliferous and terrigenous influences and the role of scavenging from seawater may be estimated from a sample's inferred depositional distance (km) from the spreading ridge, the major element chemistry, and the stratigraphie context.
Journal ArticleDOI
Evaluation of the coprecipitation of incompatible trace elements with fluoride during silicate rock dissolution by acid digestion
TL;DR: In this article, the coprecipitation of trace elements into insoluble fluoride precipitates in mafic and ultramafic silicate rocks was estimated quantitatively, and suggested an effective method of digestion that can suppress completely fluoride precipitation.

Ian Jarvis,Kym E. Jarvis +1 more
TL;DR: The rare earth elements (REE) and Y were determined in 15 international standard sediments from France, German Democratic Republic, Canada and the U.S.A. as discussed by the authors.

An accurate procedure for the determination of the rare earths by neutron activation
TL;DR: In this paper, the average precision for duplicate analyses by different analysts was found to be better than ± 4 percent mean deviation for a shale with a total rare earth content of 200 ppm.

Determination of rare earth elements in geological materials by inductively coupled argon plasma/atomic emission spectrometry
J. G. Crock,F. E. Lichte +1 more
TL;DR: In this paper, a method for the determination of trace-level rare earth elements (REE) in geological materials using an ICAP 63-channel emission spectrometer is described, where separation and preconcentration of the REE and yttrium from a sample digest are achieved by a nitric acid gradient cation exchange and hydrochloric acid anion exchange.
