    Fractionation of rare earth elements in tropical soils from marine mudstone along a toposequence by Marvin D. Cascante, Cho-Yin Wu, Zeng-Yei Hseu

    Published 2025-01-01
    “…Increasing ∑LREEs/∑HREEs ratios (ranged from 1.5 to 3.9), δCe (ranged from 0.3 to 1.0), and δEu (ranged from 1.1 to 1.4) values were observed relative to the decreasing elevation, which was dictated by the solubility and mobility of the elements during the transportation processes, provoking the fractionation of REEs. δCe positively and significantly (p < 0.001) correlated with dithionite-citrate-carbonate extractable iron, indicating the close interactions of iron oxides and the redox chemistry of Ce. …”
