自然资源部第三海洋研究所-中国科学院南海海洋研究所-南沙群岛及其邻近海区综合科学考察（八五）-大面观测-表层沉积物中Pb含量范围及平均值-1992-1995

本数据集针对南海海域，收集了1972-2016年多个南海海域综合调查项目工作，包括Ti/Nb比值、Zr/Hf比值、稀有金属元素（Zr、Sn、Ti、Y、Nb、Ta、Ce、La、Nd、Th）、主量元素Na2O等、微量元素Li等、稀土元素（REE）等海洋沉积化学要素调查数据。数据集包含21个项目， 133699个数据，主要通过对收集、调查的历史资料规范化整理、分析综合而成。

This dataset targets the South China Sea, and compiles marine sedimentary chemical survey data from multiple comprehensive marine investigation projects conducted in this sea area between 1972 and 2016. The collected parameters include Ti/Nb ratio, Zr/Hf ratio, rare metal elements (Zr, Sn, Ti, Y, Nb, Ta, Ce, La, Nd, Th), major elements such as Na₂O, trace elements such as Li, and rare earth elements (REE), among others. The dataset contains 133,699 data points from 21 projects, and was primarily compiled through standardized processing, analysis and integration of the collected historical survey data.
