This data release contains whole-rock major, minor, and trace element geochemical data for carbonatite samples from the Mountain Pass rare earth element (REE) deposit located in southeastern California. The Mountain Pass deposit is the largest REE deposit in the United States and in 2021, produced 43,000 metric tons (expressed as rare-earth-oxide equivalent; U.S. Geological Survey, 2022). Samples include a suite of outcrop samples (2018) and a suite of composite samples (2019). Data are reported in comma-separated values (CSV) files. All column headings and abbreviations are explained in the metadata.
