Summary
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.

Purpose
This data release presents a compilation of results of geochemical analyses of rock samples collected by the U.S. Geological Survey of carbonatite samples at the Mountain Pass rare earth element deposit, southeast California. The purpose of this work was to gather information on this deposit and allow comparison with other carbonatite-hosted deposits. These data are made available for use in geologic and exploration studies.
