Factors influencing the precision and accuracy of Nd isotope measurements by thermal ionization mass spectrometry
TL;DR: In this paper, a 4-step acquisition scheme was proposed to measure all isotope ratios dynamically by thermal ionization mass spectrometry (TIMS); the aim being to minimize the dependency of all mass fractionation-corrected ratios on collector efficiencies and amplifier gains.

The influence of igneous processes on the chromium isotopic compositions of Ocean Island basalts
P. Bonnand,Régis Doucelance,Maud Boyet,Patrick Bachèlery,Chantal Bosq,Delphine Auclair,Pierre Schiano +6 more
TL;DR: In this article, the first stable chromium isotopic data for a suite of ocean island basalts (OIB) was presented, in order to investigate the Cr isotope fractionation during major igneous processes such as partial melting and fractional crystallisation.

Ce isotope systematics of island arc lavas from the Lesser Antilles
Nina Bellot,Maud Boyet,Régis Doucelance,Christian Pin,Catherine Chauvel,Catherine Chauvel,Delphine Auclair +6 more
TL;DR: In this paper, a chemical purification technique for Ce, and mass spectrometric technique to perform accurate and reproducible analyses of Ce isotopes of natural samples are presented. But the results are limited to the use of Ce as isotopic tracer.

Radiogenic and stable Ce isotope measurements by thermal ionisation mass spectrometry
TL;DR: In this article, the authors developed a static acquisition method associated with 1013 Ω amplifiers that allows the precise determination of the 140Ce peak tailing effect on the lighter Ce isotopes and the reduction of the counting time necessary to obtain a high precision isotopic composition.
Formation of the Ce-Nd mantle array: crustal extraction vs. recycling by subduction
Claudine Israel,Maud Boyet,Régis Doucelance,P. Bonnand,P. Frossard,Delphine Auclair,Audrey Bouvier +6 more
TL;DR: In this article, the authors presented new measurements of 138Ce/142Ce and 143Nd/144Nd isotopic ratios in terrestrial and extra-terrestrial samples, and proposed a recycling model to reconstruct the mantle array with the participation of both oceanic crust and sediments in the mantle through time.
