Abstract

Abstract

Measurement of major elements, trace elements and rare earth elements (REY) for sediment Core GC11 collected in the central Indian Ocean Basin were performed. Based on the analysis of interelemental correlation, REY enrichment and post-Archean Australian Shale (PAAS) normalization style, the factors impacting the REY enrichment are discussed. The study suggests that: the total amount of REY varies from 400.64×10⁻⁶ to 742.74×10⁻⁶, with an average of 658.41×10⁻⁶, which is slightly lower than that of Core GC02, however, is equivalent to that of the zeolite-bearing rich deep-sea deposit in the Core DSDP213 . The sediment exhibits distinct negative abnormal δCe and lower (La/Yb)_N为0.42, with obvious positive correlation between REY and P₂O₅. The average value of CaO/P₂O₅ ratio is 2.3, demonstrating that the bio-apatite may be the main host mineral of REY. Although there is positive correlation between REY and Fe and Mn, hydroxyl hydrate of Fe and Mn have low impact to the enrichment of REY for the distinct negative abnormal δCe. The mixture with the terregeneous materials maybe the main cause inducing the differences of REY enrichment degree, δCe and PAAS normalization style.
