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.
