METADATA Identification_Information: Citation: Citation_Information: Originator: Dr. Greta J. Orris Originator: Dr. Richard I. Grauch Publication_Date: 2002 Title: Rare Earth Element Mines, Deposits, and Occurrences Edition: First Geospatial_Data_Presentation_Form: Microsoft Excel 98 spreadsheet Series_Information: Series_Name: USGS Open-File Report Issue_Identification: 02-189 Publication_Information: Publication_Place: Tucson, AZ Publisher: U.S. Geological Survey Description: Abstract: This dataset contains location, geologic and mineral economic data for world rare earth mines, deposits, and occurrences. The data in this compilation were derived from published and non-published sources. Purpose: 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. Supplemental_Information: This dataset consists of one Excel 98 workbook file, OF02189. OF02189.xls fields include deposit type, deposit or district name,country,state or province, latitude, longitude, source of location information, tonnage-grade, source and date of estimate(s), production status, REE mineralogy, other ore or significant minerals, gangue and rock-forming minerals, age, age-dating method, host rock(s), company, comments, and references. Time_Period_of_Content: Currentness_Reference: The currentness of the data varies from site to site depending on the recentness of the source materials. Time_Period_Information: Single_Date/Time: Calendar_Date: 2001 Status: Progress: Complete Maintenance_and_Update_Frequency: No updates are planned.

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. Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: The accuracy of file data attributes is highly variable, especially for some parts of Africa and Asia. Most locations are believed to be within 2-5 minutes of the exact location; some locations are for the nearest town, and other locations are of undetermined accuracy. Location errors are a result of inadequate or incorrect original data, error caused by multiple locations with the same name, and error introduced by data entry or location format conversion. The data tables were spot-checked against the original data. Logical_Consistency_Report: Point data are given in degrees and minutes. Completeness_Report: This report is the most complete compilation of rare earth mines, deposits, and occurrences known. However, it is highly likely that there are additional occurrences of rare earths that are not included. In addition, data for many of the sites are incomplete. Determination of latitudes and longitudes for some sites were impossible given the available data. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The latitudes and longitudes were largely taken from Published data or determined from descriptions of the location using the maps available to us or internet-based gazeteers such as the GEOnet Names server on the National Imagery and Mapping Agency's database. The accuracy of these locations varies with the detail of the original information.
