The cerium isotope fingerprints of redox fluctuation in bauxites

Wenshuai Li et al.

Summary: We measured the Ce concentration, oxidation state, and isotope composition of bauxites developed on the Columbia River Basalts to evaluate the impacts of redox and non-redox processes on the Ce isotopic variability on Earth's surface. The Ce anomalies and isotope shifts in the bauxites reflect the redox cycle of Ce and Mn in the regolith, indicating the potential of using Ce species isotopes and anomalies to record terrestrial redox status and fluctuation.

Ce and Nd stable isotope purification and determination of geological samples by MC-ICP-MS

Jiang-Hao Bai et al.

Summary: The combined study of Ce and Nd stable isotopes is promising, and a novel two-stage ion-exchange chromatography method is introduced to purify Ce and Nd efficiently. This method has advantages in high-precision analysis and can contribute to the study of Ce and Nd isotope geochemistry.

Heating events in the nascent solar system recorded by rare earth element isotopic fractionation in refractory inclusions

J. Y. Hu et al.

Summary: Research found that group II calcium-aluminum-rich inclusions are formed through a two-stage process involving fast evaporation and near-equilibrium recondensation, contrary to the expected scenario of equilibrium condensation. Calculated time scales are consistent with heating events similar to FU Orionis or EX Lupi-type outbursts of eruptive pre-main-sequence stars.

Cerium stable isotope analysis of synthetic and terrestrial rock reference materials by MC-ICPMS

Hamed Pourkhorsandi et al.

Summary: Cerium is the most abundant rare earth element in the solar photosphere, CI chondrites, and the Earth. A modified ion chromatography procedure for Ce separation was developed, and Ce stable isotopes were analyzed in various igneous and sedimentary geochemical reference materials. The majority of samples showed heavier Ce isotopic composition than the standard, with a homogenous delta Ce-142 in most rocks.
