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第四纪沉积地球化学与矿产资源-大面观测-黄铁矿和石膏共生组合沉积特征表-1984-1991

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 focuses on the South China Sea, collecting marine sedimentary chemical survey data from 21 comprehensive investigation projects conducted in the South China Sea between 1972 and 2016. The surveyed 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 a total of 133,699 data records, which were primarily developed through standardized sorting, analysis and integration of the collected historical survey materials.
