Rare earth database for Peru

The dataset integrates over 30,000 rare earth elements' records from national agencies and university repositories and is classified by sample source, including stream sediments, rocks and minerals, deep and surface soils, tailings, and industrial materials. Each record (element concentration in ppm) contains geographic coordinates, year osf sampling, administrative region, province, and district, and link to source. This structure enhances comparability and interpretation across geological and environmental contexts.该数据集整合了来自国家机构与高校馆藏的超3万条稀土元素记录，并按样本来源进行分类，涵盖河流沉积物、岩石矿物、深层与表层土壤、尾矿以及工业材料。每条以ppm（百万分比浓度）标注元素浓度的记录均包含地理坐标、采样年份、行政区、省份与区县信息，以及来源链接。该结构提升了地质与环境场景下的可比性与可解释性。
