G.J. Orris and R.I. Grauch compiled the data on world Rare earth mines, deposits, and occurrences from previously published compilations, new published sources, "gray" literature, company internet sites, USGS databases, and other sources. Locations were commonly taken from published sources, no effort was made to determine the correctness of these data. Other locations were found using the GEOnet Names server on the National Imagery and Mapping Agency's website, www.nima.mil, and other on-line gazeteers. Still other locations were determined using available maps of varying scales. Most of the latitudes- longitudes are believed to be within 5 minutes of their true locations, but some locations from published sources may be even less accurate.
This dataset was compiled for the University of Arizona's Center for Mineral Resources Rare Earth monograph, a summary document intended to reflect our current knowledge of the geology and mineral economics of the rare earths, including yttrium.
