自然资源部第三海洋研究所-中国科学院南海海洋研究所-南海西北部陆架沉积物元素地球化学组成与分布-大面观测-C11样品主量数据-201201-201512

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， 133718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 marine domain, and compiles marine sedimentary chemical survey data from multiple comprehensive investigation projects conducted in this area from 1972 to 2016. The surveyed parameters cover Ti/Nb ratio, Zr/Hf ratio, rare metal elements (Zr, Sn, Ti, Y, Nb, Ta, Ce, La, Nd, Th), major elements including Na₂O, trace elements including Li, and rare earth elements (REE). The dataset contains 133,718 valid data points from 21 projects, and was primarily constructed via standardized organization, analysis and integration of the collected historical survey data.
