稀土元素和钇在深海沉积物中富集，是一种很有前景的稀土新资源。为了了解热液作用对南太平洋东部深海沉积物中稀土元素富集的影响，对南太平洋东部Yupanqui盆地S 021 GC 17重力岩心样品进行了详细的岩性、沉积物地球化学和原位矿物地球化学分析。S 021 GC 17的富含REY的泥浆是深棕色至黑色沸石粘土，REY含量（σ REY）范围为1057至1882 ppm（平均1329 ppm）。富稀土泥体表现出重稀土元素富集模式，Ce明显亏损，Eu在后太古代澳大利亚页岩（PAAS）标准化稀土图解中呈现正异常。相比之下，S 021 GC 17的泥质岩在海水标准化稀土元素图上表现出轻稀土元素富集模式和Ce、Eu的正异常。岩芯中REY总丰度与CaO、P2 O 5、Fe 2 O3和MnO浓度呈正相关。利用激光烧蚀-电感耦合等离子体质谱（LA-ICP-MS）对生物磷灰石中微量元素含量的原位分析表明，生物磷灰石化石中含有较高的REY含量（998 ~ 22497 ppm，平均9123 ppm），表明它们是REY的主要载体。生物磷灰石的原位Nd同位素值高于太平洋海水的平均值。铁锰微结节分为水成型和成岩型，平均REY浓度分别为1586和567 ppm。富稀土泥体中高含量的Fe-Mn-Ba-Co-Mo、σ REY与Fe-Mn的正相关性、Fe/Ti和Al/（Al + Fe + Mn）比值以及LREE富集模式，结合生物磷灰石化石显示的高Nd同位素值，强烈表明热液流体在南太平洋东部富稀土沉积物的形成中起了重要作用。
Rare earth elements (REEs) and yttrium (Y), together known as REY, are extremely enriched in deep-sea pelagic sediments, attracting much attention as a promising new REY resource. To understand the influence of hydrothermal processes on the enrichment of REY in deep-sea sediments from the eastern South Pacific Ocean, we conducted detailed lithological, bulk sediment geochemical, and in situ mineral geochemical analyses on gravity core sample S021GC17 from the Yupanqui Basin of eastern South Pacific. The REY-rich muds of S021GC17 are dark-brown to black zeolitic clays with REY contents (sigma REY) ranging from 1057 to 1882 ppm (average 1329 ppm). The REY-rich muds display heavy rare earth elements (HREE) enriched patterns, with obvious depletions in Ce, and positive anomalies of Eu in Post-Archean Australian Shale (PAAS)-normalized REE diagrams. In contrast, the muds of S021GC17 show light rare earth elements (LREE) enriched patterns and positive anomalies of Ce and Eu in the seawater-normalized REE diagrams. Total REY abundances in the core show positive correlations with CaO, P2O5, Fe2O3, and MnO concentrations. In situ analyses of trace element contents by laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) demonstrate that bioapatite fossils contain high REY concentrations (998 to 22,497 ppm, average 9123 ppm), indicating that they are the primary carriers of REY. The in situ Nd isotope values of bioapatites are higher than the average values of seawater in Pacific Ocean. Fe-Mn micronodules are divided into hydrogenetic and diagenetic types, which have average REY concentrations of 1586 and 567 ppm, respectively. The high contents of Fe-Mn-Ba-Co-Mo, the positive correlations between sigma REY and Fe-Mn, the ratios of Fe/Ti and Al/(Al + Fe + Mn), and the LREE-enriched patterns in the REY-rich muds, combined with high Nd isotope values shown by bioapatite fossils, strongly indicate that the hydrothermal fluids have played an important role in the formation of the REY-rich sediments in the eastern South Pacific Ocean.
